Lesson Synopsis

In this lesson, students will use a variety of models and information resources to demonstrate and investigate how geologic forces of nature cause rapid changes in the

Earth’s surface.

TEKS

The Texas Essential Knowledge and Skills (TEKS) listed below are the standards adopted by the State Board of Education, which are required by Texas law. Any

standard that has a strike-through (e.g. sample phrase) indicates that portion of the standard is taught in a previous or subsequent unit. The TEKS are available on the

Texas Education Agency website at http://www.tea.state.tx.us/index2.aspx?id=6148.

3.6 Force, motion, and energy. The student knows that forces cause change and that energy exists in many forms. The student is expected

to:

3.6C Observe forces such as magnetism and gravity acting on objects.

3.7 Earth and space. The student knows that Earth consists of natural resources and its surface is constantly changing. The student is

expected to:

3.7B Investigate rapid changes in Earth's surface such as volcanic eruptions, earthquakes, and landslides.

Supporting Standard

Scientific Process TEKS

3.1 Scientific investigation and reasoning. The student conducts classroom and outdoor investigations following school and home safety

procedures and environmentally appropriate practices. The student is expected to:

3.1A Demonstrate safe practices as described in the Texas Safety Standards during classroom and outdoor investigations, including observing a schoolyard habitat.

3.2 Scientific investigation and reasoning. The student uses scientific inquiry methods during laboratory and outdoor investigations. The

Advance Preparation

1. Obtain the MSDS for vinegar, baking soda, detergent, and food color.

2. Gather or prepare information resources (age-appropriate books, magazines, Internet sites, videos, etc.) that students can use as they investigate earthquakes,

volcanoes, tsunamis, and landslides and the scientists who study them.

3. Prepare a shoebox lid or plastic container lid by drawing a 3” diameter circle in the center of the lid. This will be the area where students place the marbles in theEngage activity.

4. Preview the earthquake video clip(s) you will be using in the Engage. Refer to the Resources section.

5. Download or bookmark FEMA’s “Earthquake Legends”.6. Prepare the Teacher Resource: Rapid Changes to the Earth’s Surface Concept Map.

11. Bookmark or download hazard and activity maps for earthquakes, volcanoes, and landslides. Refer to the Resources section for links.

12. Prepare attachment(s) as necessary.

Background Information

This lesson addresses TEKS related to changes in the surface of the Earth.

During this lesson, students build upon previous experiences with forces and properties of matter and apply those understandings to the study of the Earth as a system. Students learn about forces

of nature that shape the physical features of the Earth. They examine changes due to rapid processes, such as earthquakes, volcanic eruptions, and landslides as well as changes due to slow

processes. They will investigate the slow and rapid changes to the Earth and be expected to recognize the types of changes that occurred to the Earth to create a variety of landforms.

After this lesson students will learn about the characteristics of natural resources that make them useful in products.

ENGAGE – Forces of Nature

Notes for Teacher

NOTE: 1 Day = 50 minutes

Suggested Day 1

1. Divide the class into groups of 3–4 students.

2. Distribute a shoe box lid, plastic tub lid, or tray and about five marbles per group of students.

Explain to students that they are going to place the container in the middle of their table and then

place their marbles in the center of the circle that is drawn in the lid. Upon teacher directions, two

or three students will hold the edge of the desk and produce a gentle shaking for 15 seconds.

Students should observe what happens to the marbles.

Ask:

What were some observations from this activity? Answers will vary.

3. Collect the materials.

4. Say:

Most of the time, the Earth feels solid and firm underneath our feet. But, thousands

of times a day, somewhere on the Earth, the ground will shake and tremble – that’sabout once every 11 seconds.

5. Inform students that the rock beneath the Earth’s surface is under great pressure. The force ofthe pressure may cause sudden jolts and movements. Those sudden jolts and movements

produce vibrations that shake the surface of the Earth.

Ask:

Who knows what we call this rapid vibration or shaking of the Earth? (Earthquake)

6. Say:

“Quake” means to shake.Many earthquakes are too small for us to feel, but scientists have very sensitive

instruments that can record this movement.

Most earthquakes last less than one minute.

7. Say/Ask:

The duration of a small earthquake is less than a second; a moderate-sized

earthquake lasts a few seconds.

Materials:

container (such as a shoe box lid, plastic tub lid, or tray,

see Advance Preparation, 1 per group)

marbles (5 per group)

timing device (such as a stopwatch or a clock with a second

hand, 1 per group)

video clip(s) – earthquake

Instructional Notes:

Social studies TEKS refer to these events/processes as “natural disasters,”

and rightly so. Their focus is on the human condition. Science recognizes

the impact of these processes on life, as well. Without these processes,

Earth would not have evolved into the “living” planet as we know it. These

processes are both destructive and constructive.

Grade 3

Science

Unit: 05

Lesson: 02



In 2004, a deadly earthquake in the Indian Ocean lasted between 500 and 600

seconds (8 to 10 minutes), and the recent earthquake in Japan was 360 seconds, or

6 minutes.

Have any of you ever experienced an earthquake? Answers will vary; however, allow

students to share experiences they may have had with an earthquake.

8. Inform students that you are going to show them what a real earthquake might look like or feel

like. Play video clip(s). (See the Instructional Notes.)

9. At the end of the clip(s), allow students the opportunity to Think-Pair-Share one way the

earthquakes changed the Earth or the things on it.

Ask:

Did these changes happen quickly or slowly? (Quickly)

Why might an earthquake be called a “force of nature”? Answers may vary, but

students should remember that a force (push or pull) is needed to make anything move or

shake. In this case it is a natural force, not man-made (e.g., explosion, heavy drilling

equipment, building demolition, etc.) and it is powerful.

Remind students of the first activity they did with the marbles earlier in the lesson.

10. Say:

People long ago didn’t understand earthquakes and the forces that caused them.They developed myths and legends to explain this unusual and frightening event.

Share one or two of these legends with the students. (See the Instructional Notes.)

11. Explain that scientists who study the Earth have made observations and used tools/instruments

to learn more about earthquakes.

Ask:

Why might scientists want to study earthquakes and other forces of nature? Answers

will vary.

12. On the board, a chart, or overhead, set up a Tchart labeled “Forces of Nature”. Label onecolumn Geological (land/Earth) and the other Meteorological (air/atmosphere/weather). Facilitate

a discussion.

We have just learned that earthquakes are forces that rapidly change the Earth’ssurface.

What other forces of nature rapidly change the Earth’s surface? Responses may or

may not include tsunami, volcanic eruption, landslide, tornado, hurricane, flood, etc. This is

really a ‘preassessment’ of what they currently know or think they know.Why do scientists study processes or events that rapidly change the Earth’ssurface? Answers may vary, but could include that the more scientists understand about

processes or events that change the Earth, the more information they can supply to the public

about how to prepare for or survive such an event.

13. As students share their answers, record the forces on the T-chart according to whether they are

geological or meteorological. Attach the appropriate clip art picture (from the Teacher Resource:

Clip Art: Forces of Nature) next to the word to assist in understanding. Inform students that, for

now, the focus will be on geological (land/Earth) events or processes that begin deep inside the

Earth.

14. Use the Teacher Resource: Rapid Changes to the Earth’s Surface Concept Map to

formatively assess students’ initial understandings and explanations of the lesson concepts(What events/processes cause rapid changes to the Earth’s surface and are they related?). Seethe Teacher Resource: Rapid Changes to the Earth’s Surface Concept Map for directions.

15. The concept map will be used in the next activity.

Be sensitive to students who may have experienced trauma during a natural

disaster.

Earthquake Legends (FEMA for Kids)

http://www.fema.gov/kids/eqlegnd.htm

Teacher Resource: Clip Art: Forces of Nature is provided for most of the

“forces of nature” that students might mention. Adding a sketch or illustration

to the T-chart and/or pre-investigation concept map can aid comprehension.

Set-Up: (Possible sort shown)

Misconception:

Students may think that the Earth has always been the

same as it is today.

Check For Understanding:

Student responses for the Forces of Nature chart provide teachers with an

opportunity to formatively assess students’ prior knowledge of this concept.

EXPLORE – Earth Changes Suggested Day 2

1. Direct students’ attention to the concept map they constructed in the previous lesson and brieflysummarize their current ideas and understandings.

2. Prior to the discussion of student questions, discuss and model “thick” and “thin” questions if timepermits. See the Optional Teacher Resource: Asking Questions SAMPLE.

3. Introduce the Teacher Resource: PowerPoint: Earth Changes. Instruct students to watch and

see if the information in the presentation provides evidence to support any of their ideas on the

class concept map. Teacher notes are included in the PowerPoint. At the conclusion of the

slideshow:

Say:

I will distribute sticky notes to each of you to record two questions about volcanoes,

two questions about landslides, and two questions about earthquakes.

4. Say:

You will have a few minutes to sort your questions on earthquakes, landslides, and

volcanoes to determine if any of the questions are similar to the other members of

your table group. Then, as a class, we will sort our questions about forces of nature

(earthquakes, volcanoes, and landslides) on a question board (or chart).

5. Collect the sticky notes from each group.

6. When questions have been collected,

Ask:

Where might we search for answers to our questions about these forces of nature?

Responses will vary, but may include books, the Internet, magazines, newspaper, videos, a

scientist, etc.

Is it possible for us to bring in and experiment with a large section of the Earth to

see how it moves and changes? No, this would be impossible.

What would be another way we could experiment with the way forces of nature

affect/change the surface of the Earth? Use a model.

What is a model? A model is a representation of something in the real world that helps us

understand how the real thing looks or works.

What are some models that we have used so far this year to represent the real

world? We have used models for the water cycle, for the Earth (a globe), landforms (shaving

cream), etc.

How can models help us better understand how the Earth works? Answers may vary.

7. Discuss each of the three forces students learned about during the PowerPoint, and add the

information to the concept map.

8. Prior to tomorrow’s lesson, sort through the questions in order to reduce the number ofduplicates.

Current events related to natural disasters can provide that “teachable

moment”. Students want to know and understand what has happened. Keep

in mind that young students can be easily overwhelmed and frightened by

real-time videos and raw images of destruction.


The student responses on the sticky notes provide a formative assessment

for the teacher about students’ understanding of forces of nature.

EXPLORE/EXPLAIN – Independent Exploration Suggested Day 3

1. Say:

In our previous lesson, you generated several questions. Today, you will begin to

research an answer to the questions.

2. Independent Exploration. Depending on the available resources and student needs, you may

want to have students work in pairs or groups to look for answers to questions on the question

board.

3. Say:

There are several resources available for you (and partner or group) to use.

Some strategies to remember as the research is conducted include: skim and scan

(ELAR 3.26B) and taking simple notes (ELAR 3.26C).

4. Students should now have the opportunity to choose a question to research from the question

board. They will spend the rest of the science class session working on their question. They

should have the opportunity to research a question about volcanoes, one about earthquakes,

and one about landslides. This will assist students in understanding the content more fully in

order to be successful on the Performance Indicator.

5. Toward the end of the instructional period, bring the exploration to a close by having students

share what they have discovered so far and how it helps them better understand processes that

rapidly change the Earth.

6. Any relevant learning can be added to the concept map. And, there may be additional questions

that arise during exploration and modeling which can be added to the question board.

Materials:

print and electronic resources (children’s books,magazines, articles, Internet sites, videos, etc.)

index cards (for recording answers)

sticky notes (for recording answers)

slips of paper (for recording answers)

question board or chart(s)

concept map


Students should have the opportunity to share their learning with the rest of

the class. This supports ELPS skills of reading, writing, listening, and

speaking.


The independent exploration is in alignment with the ELAR standards

(3.25A, 3.25B, 3.26Aii, 3.26Aiii, 3.26B and 3.26C).

These standards are in the 3rd 6 weeks ELAR.

The independent exploration is also one way for students to practice the

process skills 3.2D, 3.2F, 3.3A, and 3.3D.

Science Notebooks:

Student research work should be done in the science notebook

EXPLORE/EXPLAIN – Earthquake Models Suggested Day 4

1. The following three questions are to “think about it” and are not being answered at this time.Ask:

How can a model help us better understand the way our Earth works?

How is the model like the real thing?

How is it different?

2. Introduce the earthquake model(s). See the Teacher Resource: Earthquake Model for pictures

and directions.

Display or distribute the plastic storage box(es) that will represent a slab of the Earth’s crust.The box(es) must be weighted down with soup cans or rocks, covered with the lid, and then

turned upside down. Cover the flat portion on the bottom of the box with a colored paper cut-

out.

Explain to students that most earthquakes occur when large sections of the Earth’s surface(plates) suddenly jerk or shift. This jolt or sudden movement produces vibrations in the

Earth’s crust. The ruler will be used to create these vibrations or earthquake. Demonstrate bytapping the end of the box (in the middle of the box end) with the ruler (wrist action, like in

tennis or fly-fishing, works well).

Place the two cube “buildings” at opposite ends of the colored paper cutout. Mark theirpositions by tracing around their bases.

Pour a thin strip of rice (Earth materials) between the two “buildings”. Use the craft stick toshape it into a compact path. Trace around its perimeter.

3. Explain that some earthquakes are barely noticeable, whereas other earthquakes can cause

tremendous changes to the Earth’s surface.Ask:

How might we use this model to show the difference? Answers may vary, but students

may suggest changing the amount of force or changing the location of the force.

4. Lead students to an investigable question for each force (gentle, more vigorous), and discuss

how to ensure a fair test. (Example: How does the size of an earthquake affect the amount of

change or damage to the Earth’s surface? The location?)

5. Students should have the opportunity to draw before and after pictures for each of the

magnitudes of force tested. Students should predict the outcome prior to each test.

6. Either demonstrate the simulated earthquake, or instruct students to gently tap one end of their

box with the ruler continuously for ___ seconds. (The teacher will choose the length, generally

anything from 10-30 seconds.) Observe and describe changes to the surface (rice and

buildings).

7. Reposition the rice and buildings. Use greater force to tap the same end of the box continuously

for the same number of seconds. Discuss and compare the results.

8. Repeat the procedure, but tap the other end of the box. Discuss the changes to the surface.

Ask:

Based on this model, what claims can you make about changes to the Earth’ssurface caused by earthquakes? Students should suggest that the amount of change or

damage depends on the size of the earthquake or its location. They should be able to

support their claims with evidence.

9. Students should record their claims and evidence in their science notebooks.

10. Explain that scientists use tools and instruments to measure the size and location of

earthquakes. Ask if anyone has read about any of these instruments or tools. If not, consider

adding that question to the board.

11. Discuss the limitations of the model (size, properties, materials, etc.).

12. If the question has not yet been raised, ask students if they think we have earthquakes in Texas.

Consider adding the information to the concept map.

13. Say:

We are going to view a PowerPoint about earthquakes.

As you view each slide, make observations to identify the changes caused by

earthquakes.

You may wish to write your thoughts down in your science notebook.

14. Project the Teacher Resource: PowerPoint: Earthquakes Cause Change. It illustrates real-

world examples of changes caused by powerful earthquakes. Pause at each slide to give

students the opportunity to carefully observe and then identify changes caused by earthquakes.

Allow students to share their thinking.

Movies depict the ground opening up and swallowing buildings, cities, etc.

Shallow crevasses can form during earthquakes. Faults, however, do not

gape open during an earthquake.

In a climate of trust, “going public” with one’s claims and evidence can be as

fun as the classic show-and-tell session with its exchange of questions and

answers. “Students have to be made aware that one of the jobs of scientists

is to put something “out there” for other scientists to question.” (Norton

Meier, et. al., 2008).

Misconception:

Students may think that the ground opens up during an

earthquake.


Students should have the opportunity to share what they have learned. This

provides the teacher with a formative assessment of the students’

understanding of the concepts.

Science Notebooks:

Students should have the opportunity to draw and label the model and

predict each outcome. They can record their observations after each test.

Students should record claims and evidence.

EXPLORE/EXPLAIN – Tsunamis Suggested Day 5

What is a tsunami and what do you already know about tsunamis? As needed, explain

Attachments:

Handout: Lesson Saves Lives (1 per student or 1 for

that a tsunami is a series of huge waves often caused by an earthquake (or other

disturbance) under the ocean. The waves can travel at speeds as fast as 500 miles per hour

(speed of a jet plane) and may reach a height of 100 feet/30 meters (10 story building) by the

time they hit the coast or shore.

2. Ask: (This is a Think-About-It question.)

Why would it be important to know about processes/events that rapidly change the

Earth?

3. Distribute or project a copy of the Handout: Lesson Saves Lives. Have students read the news

story to learn about a 10-year old hero.

Ask:

How did the girl’s understanding of tsunamis save lives? (She was able to warn people

of the danger, which caused them to clear the shore.)

What changes may signal a tsunami? (Noticeable changes may include an earthquake

along the coast; unusual bubbles in the ocean water; receding waterline; sudden period of

quiet in a normally surf-pounded area; or a roaring sound coming from the ocean.)

4. Explain to students that a tsunami can also rapidly change the land when the waves hit the coast.

Share visuals that illustrate the changes caused by this force of nature.

Ask:

What other changes might a tsunami cause when it hits the shore? (Destroy or

change the shape of the coastline; cause inland flooding; uproot plants; sweep away

buildings, vehicles, etc.; fires)

5. Independent Exploration: Students can continue to work in pairs or groups on their

independent exploration.




7. Any relevant learning can be added to the concept map. There may be additional questions that

arise during exploration and modeling which can be added to the question board.

Refer to the Resources section for links to 1) NOVA tsunami animation and

2) bird’s eye views of the coastal areas before and after the March 11, 2011

Japan tsunami. Students should be able to describe changes to the Earth’s

surface from these photos.

Misconceptions:

Students may not realize that a tsunami is a series of

waves.

Students may think weathering and erosion are often

thought of as being slow earth processes. In reality,

weathering and erosion can be rapid processes. Hurricanes

and tornadoes are just two events that increase the rate of

weathering and erosion.


Students should have the opportunity to share what they have learned. This

provides the teacher with a formative assessment of the students’

understanding of the concepts.

EXPLORE/EXPLAIN – Volcanoes Suggested Day 6

1. Display the “mountain” model. (The Teacher Resource: 3D Volcano sows step-by-step

instructions how to construct the volcano with a mountain top.)

Ask:

What is this landform? Explain. (Mountain; elicit characteristics)

2. Remove the top or peak of the mountain to expose the hole in the top.

Ask:

Now what do you think this is a model of? Volcano

3. Explain that a volcano is a special kind of mountain.

4. Say:

In your science notebooks, draw a picture of the mountain model and the volcano

model before the eruption.

5. Say:

Carefully observe what happens when the model volcano “erupts”. Pay closeattention as you will be drawing and labeling the “eruption” in your notebook.

6. Demonstrate a volcanic eruption. Allow a few minutes for students to draw and label the eruption

in their science notebooks. Using the terms magma, core, and lava would be appropriate but

formal definitions are not necessary.

7. Ask:

How is this model like the real thing? How is it different? (A model of a volcano will show

an opening where the magma will move up through the mountain. It demonstrates the forces at

work that cause pressure. In real life, chemicals are not mixing inside. Molten rock is found

deep inside the Earth. Size, material of composition, and mechanics of the eruption are all

different.)

8. Ask:

What do you think happens if a volcano erupts under the water? Accept all answers.

9. Explain that the Hawaiian Islands were formed by underwater volcanoes. Each time the volcano

erupts under water another layer is added to the rock and builds continually until it is tall enough

to rise above the water’s surface.

10. Ask:

How can rapid changes to the Earth’s surface be helpful and/or harmful? Earthquakes

and volcanoes create new land, but can also destroy life and property. Earthquakes and

volcanoes can release the pressure (forces) that have built up within the Earth.

Where do most earthquakes and volcanoes occur? Earthquakes occur mostly at fault

Scientists have not gathered enough data to suggest that earthquakes

cause volcanic eruptions. But, earthquakes often precede a volcanic

eruption. Conversely, volcanic activity is known to cause earthquakes.

Earthquake information: http://earthquake.usgs.gov/earthquakes/map/

Misconceptions:

Students may think that volcanoes are found only on land.

Students may think that all volcanic eruptions are violent.

Students may think earthquakes and volcanic activity occur

in random locations across the Earth.

Students may think earthquakes cause volcanoes to erupt.

Science Notebooks:

Students should sketch a picture of the mountain model and the volcano

model before the eruption.

lines. In the U.S., most earthquakes occur in Alaska.Active volcanoes are usually located on

the edge of contintents; specifically along the Pacific Ring of Fire. Kilauea Volcano in Hawai’i isthe most active volcano in the United States.

Do you think we have any earthquakes or volcanoes in Texas? Accept all answers.

11. Project one or more real-time earthquake maps. Explain to students what the symbols and lines

represent on each map.

12. Ask:

Based on the map(s), where do most earthquakes occur? Most occur along the west

coast of the U.S. or around the rim of the Pacific Ocean.

13. Have we had any earthquakes in Texas in the last 7 days? Inform students that

earthquakes can happen anywhere, but most earthquakes happen along faults.

14. Distribute or project the volcano hazard map of the U.S. Once again, explain the symbols and

discuss the patterns. Explain to students that Texas does not have any active volcanoes, but it

has a volcanic past. The Davis Mountains were formed by volcanic activity millions of years ago.

In addition, Pilot Knob is an ancient volcano near Austin, Texas.

15. Add any relevant learning to the concept map and any additional questions to the question

board.

EXPLORE/EXPLAIN – Landslides Suggested Day 7

1. Say/Ask:

This lesson is entitled Forces of Nature: Inside and Out. We have investigated

forces that begin deep inside the Earth.

What other forces can rapidly change the surface of the Earth? Answers may include

the atmospheric forces not studied in this lesson.

2. Inform students there is one event that may be set off by both forces inside the Earth and/or

changes in the atmosphere that surrounds the Earth. Share a video clip or excerpt from a book

about landslides.

3. Discuss the main points in the video or excerpt. Include:

1) Where landslides happen (steep slopes)

2) Causes (excess water in the soil)

3) Changes in the surface (strips the surface of the Earth, exposing the soil)

4) The energy, forces, and motion involved (Energy of motion, force is gravity, and the motion is

down a slope)

4. Use the context of the video to define the word erosion (movement of rock, soil, or other earth

materials from one place to another by gravity, water, wind).

Ask:

What type of landforms would be most affected by a landslide? (Landforms with steep,

sloping slides and the low areas beneath.) A tsunami? (Coastal areas)

What parts of the United States are most affected by earthquakes? Volcanoes?

(West coast states, Alaska, and Hawaii)

Why would it be important for people near these landforms or in these locations to

know about how these processes/events change the Earth’s surface? (They will be

better prepared in case of emergency. They may build homes and bridges in safer areas or

build them to withstand the force.)

Why do scientists study processes or events that rapidly change the Earth’ssurface? (To learn more about how the Earth works; to better predict future events to save

lives and minimize damage; to find safer ways and places to build structures in areas at risk,

etc.)

In Texas, we don’t have earthquake drills and we don’t evacuate our cities becauseof volcanic activity. What forces of nature do we deal with in Texas? Answers may

include tornadoes, hurricanes, floods, blizzards, lightening, hail, dust storms, and wildfires.

ELABORATE-A Review of the Processes that Cause Rapid Changes Suggested Day 7 (continued)

1. Revisit the class concept map to flesh out any remaining ideas related to the Key

Understandings.

Ask:

What events/processes cause rapid changes to the Earth’s surface and are theyrelated? Answers may vary.

2. Ask students to complete a 3-2-1 summary in their science notebooks by responding to these

prompts.

3 important things I learned during this lesson

2 ways my ideas have changed

1 thing I enjoyed most as a learner

Science Notebooks:

Students respond to 3-2-1 prompts to summarize their learning.

Rapid Changes to the Earth’s Surface Concept Map Instructions and KEY

1. This may be the students’ first experience with concept maps. Adjust the following suggestions to provide modeling and support as needed. There is no right or wrong way to construct concept maps. However, the concepts should be arranged and connected in some logical way and address the Key Understandings and Guiding Questions. See the link in the Resources section for elaboration on this strategy.

2. Display and introduce the Rapid Changes to the Earth’s Surface Concept Map. See one example below (page 2 of 3).

3. In one box (or circle), record the word earthquake as one (geological) force of nature that rapidly changes the surface of the Earth. The connector words, “caused by,” show how the two ideas are related.

4. Using responses from the geological column of the T-chart, record any remaining ideas in separate boxes or circles around the main idea. Note: “Volcano” can be used to describe the vent in the surface of the Earth through which magma, ash, and gases erupt. It also describes the landform or structure that is produced by the ejected material.

5. Distribute a pile of sticky notes (same color) to each group of 2–4 students. With their partner(s), students brainstorm everything they know or think they know about how each of these forces changes the Earth. Model how you want the students to record their ideas by jotting each word, idea, or tidbit of information on a separate sticky note. For example, one way that earthquakes change the earth surface is “ground shaking.”

6. In round robin fashion, have the groups share their ideas with the class and post them in an appropriate area on the chart. If students have a word or idea that has already been posted, let them place their note on top of the others.

7. After all the ideas have been presented, arrange the ideas to form an interactive concept map. Note: You can either arrange the ideas with student input (if time permits) or assemble and label the map yourself prior to the upcoming Explore: “Earth Changes.”

8. As the lesson and investigation continues, any new knowledge or learning can be added using a different color of sticky note. Students will be able to see how their understanding has changed.

9. A complete concept map sample (page 3 of 3) lists some of the concepts and relationships that may surface during the lesson. This concept map will vary based on the information gained from the resources and models you chose to use. The final concept map may need to be redrawn so that it reflects only the information and evidence that students have gathered from resources and models.

Asking Questions SAMPLE

Asking questions is at the heart of inquiry. Questions should be authentic and relevant to students,

but they should also relate to the Key Understandings. The important thing is not to squelch students’

curiosity and wonder.

When investigations involve research, “thick” and “thin” questions provide different information and

lead to different results. Thin questions can help us clarify key vocabulary, facts, or data; thick

questions can expand our thinking, personalize our learning, and deeper our conceptual

understanding (McLaughlin and Allen, 2002).

Modeling and instruction: Define “thin” and “thick” questions through illustrations and examples.

Propose a thin question related to the current topic, and turn it into a “thick” one.

Thin Questions – Right There

Recall Short answer - yes/no, definition, number,

list Require very little thought How many? What are? Who is?

Thick Questions – Think and Investigate

Are involved, complex, open-ended May have multiple answers Often lead to more questions What if? How come? Why is it? I wonder. .

Do we have earthquakes in Texas? (yes/no)

*Where do most earthquakes and volcanoes

occur?

What if an earthquake happened near our

school?

How many people lost their lives in the 1906 San

Francisco earthquake? (asks for a number)

What makes earthquakes dangerous or harmful?

*How can rapid changes to the Earth’s

surface be helpful and/or harmful?

*Why would it be important to know about

processes/events that rapidly change the

Earth?

What materials are needed to build a model of a

volcano? (implies a list)

*How can a model help us better understand

the way our Earth works?

*How is the model like the real thing? How is

it different?

*Teacher-generated focus questions: These reflect the Key Understandings, but will vary based

on the models and information resources that you use in class.

Earthquake Model

Materials for Each Set-Up: plastic storage box, cans, paper cut-out, craft stick, sturdy ruler, rice, and two cube

buildings stuck together with a very small amount of peanut butter (Let this dry overnight.). (Buildings can be

made from wood cubes, plastic cubes [not interlocking], or sugar cubes.)

1. Weigh down the storage box with soup cans; invert box.

2. Use the craft stick to arrange “earth materials” on the

paper cut-out (needs to be a flat, level surface).

3. Outline the starting position for “buildings” and rice.

4. The model is ready.

5. Use the ruler to model a moderate earthquake; survey

changes to “buildings” and the “Earth’s” surface; and reposition the buildings and earth materials.

6. Simulate a major earthquake, and compare the

results. (Not pictured: Tap the other end of the box to see how distance from an earthquake affects the amount of damage or change.)

Lesson Saves Lives

In 2004, a ten year old British girl was learning about forces of nature just as

you are today. Several weeks later, she saved her family and 100 other

tourists from a huge tsunami in Thailand.

She knew about changes that often happen before a tsunami hits the shore.

She saw strange things happening in the ocean. There were lots of bubbles

in the water. Then, the water pulled away from the shore, leaving fish and

boats stranded on the sand.

Other people were fascinated by the ocean’s strange behavior. But, the

girl’s warnings caused people to quickly leave the beach before the huge

waves crashed on the shore. No one on the beach was killed. Her

understanding of earthquakes and tsunamis saved hundreds of lives.

There are other changes that may signal a tsunami. For example, there may

be a strange quietness or sucking sound when the water pulls away from

the shore. As the tsunami comes closer, the sound may change to a loud

roar. If you feel an earthquake while visiting the ocean, quickly leave the

beach and move to higher ground. The tsunami danger is not over after the

first wave. Larger walls of water will soon follow.

3D Volcano

This is the classic chemical reaction volcano model. Refer to Resources section for other models.

Note: Regardless of the model you choose, begin with a model that resembles a mountain, not a volcano.

1. Small water bottle with 30 ml baking soda,

secured with modeling clay to foil pan

2. Optional: One or two vents added with straws

3. Wadded newspaper and tape make a mountain.

4. Foil, glued sand, removable mountain top piece

5. Mountain top replaced with clay summit crater

(trim straw vents if too long like this one)

6. In measuring cup, mix 60 mL vinegar with a few

drops of dish soap and red food coloring. Pour and enjoy! (can be reloaded for additional eruptions)

Performance Indicator Instructions KEY

Draw three windowpanes to illustrate what the Earth might look like before, during, and after an extreme (rapidly occurring) event. Describe the changes made to the Earth's surface and to any living organisms or nonliving objects affected by the event. (3.2F, 3.7B)

1C, 3H, 5G

Materials: paper (plain, folded or layered into 3 sections or windowpanes, 1 sheet per student)

Instructional Procedures: 1. Have students silently reflect on the main idea for this lesson: How do forces of nature rapidly

change the surface of the Earth? Explain that they will now have an opportunity to showcase what they have learned about these extreme events. Read or project a copy of the Performance Indicator.

2. Tell students they can choose to illustrate and describe any event they have learned about during this lesson. They should keep in mind that some events are related to certain locations or landforms.

3. Use guided imagery to prepare students for the task. You may want students to close their eyes as they visualize the experience. Some suggestions follow: Picture yourself somewhere on Earth, in a safe shelter, looking out at your surroundings from a

window or door. What does the landscape look like? Is the view one of a city or the countryside? What sounds do you hear? Do you notice anything else of interest such as trees, plants animals, train tracks, towers, etc.?

4. Say: For Windowpane #1, you will draw and then describe your surroundings before the

extreme event. Suddenly, your extreme event begins to take place. Are there any warning signs (natural or

man-made, sirens)? What do you see . . . hear . . . feel . . . ? What is happening to the land, water, buildings, trees, ground, plants, etc.? You are not part of this event. But if you were, what would you do? What would you tell your friends to do?

For Windowpane #2, you will draw and then describe all of the changes that are taking place during your extreme event.

Afterwards, what changes have been made to the land or the things on it? How is the view different from Windowpane #1?

For Windowpane #3, you will draw and then describe the effects of your extreme event on the Earth’s surface.

5. Share the Performance Indicator rubric or expectations with students prior to students beginning the assessment.

6. Answer any questions students may have regarding the assessment.
