Unit: FOSS Chemical Interactions Lesson Number/s: Inv. 3, 4, and 5

Concepts: Kinetic energy is energy of motion, the particles in substances gain kinetic lose kinetic energy as they cool, substances “heat up” and “cool down” as a result of energy transfer, energy transfers between particles when they collide, energy transfer by contact is conduction, energy always transfers from particles with more kinetic energy to particles with less kinetic energy.

Rationale for this lesson study: Students will be able to explain how energy transfers between different types of matter, and that energy transfer is the transfer of KE between particles of matter.

STEM Professional: Matt Richards - ISB Chemical Engineer

Lesson refinements to observe selected student learning traits:1. All students engage intellectually in important science and engineering content.2. All students participate in science discourse with peers (equitable, accountable talk).3. All students use evidence to demonstrate conceptual understanding.

Standards:Performance Expectations -Apply scientific principles to design, construct, and test a device that either minimizes or maximizes thermal energy transfer. MS-PS3-3

Science and Engineering Practices

Disciplinary Core Ideas Crosscutting Concepts

Apply scientific ideas or principles to design, construct, and test a design of an object, tool, process or system.

Energy is spontaneously transferred out of hotter regions or objects and into colder ones.

A solution needs to be tested, and then modified on the basis of the test results in order to improve it. There are systematic processes for evaluating solutions with respect to how well they meet criteria and constraints of a

The transfer of energy can be tracked as energy flows through a designed or natural system.

Teaching for Conceptual Change

Investi-gations 1-

2-3-4

1 Elicit each student’s initial ideas. Conceptual StoryLesson 1 to launch whole unit:

● Chapter challenge● Essential question about water bottle insulation

design challenge.● Video, Narrative bubbles, or Prezi of summer

engineering design cycle example from UW.Lessons 1-2-3-4 teach science as designed.Lesson 5 is the application of concepts built in the first set of investigations 1-2-3-4.

Monday: Launch the Engineering Design Cycle ● Define the problem for students● given criteria● given constraints● Individuals do first design

Tuesday: Team design● Each student pitches own design● Group reaches consensus on design choice to

pursue

Wednesday : Build and test● Groups build and test● Collect data, display data, make Energy Diagram

Thursday: Rank the designs and materials.● Groups pitch designs to whole class● Class builds a ranking of material effectiveness

2 Prompt possible dissatisfaction with old ideas, and surface the range of students’ new ideas that make sense with their new observations.

3 Narrow the range down to the one new idea that is most plausible in this situation.

4 Reflect back to initial ideas and how each student’s understanding has changed.

Engineering Enhancement

Engineering Problem: How could we limit the transfer of thermal energy between different substances?

Learning Target: I will apply scientific principles to design, construct, and test a device that either minimizes or maximizes thermal energy transfer. MS-PS3-3

Success Criteria:1. I will test materials to determine the ability of that substance to insulate against thermal

energy transfer.2. I will design a container that will minimize or maximize thermal energy transfer.3. I will build and test the device.4. I will reflect and redesign to improve thermal insulation.

Concepts:What concepts will the students need to know before the activity:

● Heat and Kinetic Energy and thermal energy are the same concept.● Matter (solids, liquids & gases) are made of particles.● The Kinetic Energy of a particle is lower or higher depending on the substances’

state/phase of matter.What concepts are the students expected to learn through the activity:

● Energy transfers through contact between particles, the speed and density of particles will affect the transfer of kinetic energy.

Day 1 week prior: Particles are in motion when adding or removing heat from the systemReading: Particles in Motion

Observe: the FOSS-Web simulations and/or demo

Demo: Take a volume of hot water and cold water record starting temperature and keep recording temperature change each minute over a set amount of time. Ask: What caused the hot water to lose heat? Where did that heat go? What caused the cold water to gain heat (temperature)? Where did that heat come from?

NGSS Lab Lesson Enhancement - Chem. Int. Lesson 5Day 2 MONDAY: Launch the Engineering Design Cycle -- individual designs

Handout: Engineering Design Cycle Graphic Organizer (with fillable question prompts)

Define problem for students● Design an insulated bottle to keep the liquid in the bottle from losing heat

energy.● You notice that if you fill a cup with hot chocolate or tea that it will cool down

too quickly.● Create a bottle that minimizes the transfer of kinetic energy/thermal energy in

the water bottle system.Criteria for success

● Keep the bottle of water from changing in temperature by more than 10 degrees Celsius over ten minutes, when sitting in an ice bath.

Constraints● Designs must have the materials attached to the outside of the plastic bottle.● Final bottle designs must fit through a tape roll and be tested in a clear

plastic container.● Mark the bottle with sharpie level with the top of tall plastic cup, bottle must

be seated all the way in cup (not simply sitting on top of material)● Mass of the design must be _______grams or less● 20 minute build time.● Design must consider ease of use by consumer● Materials provided.

1’s Design ● Preview the materials (1 student per group at a time)● Create your own, individual, design plan that includes:

a) A labeled diagram of the insulated water bottle design.b) Your explanation of why you think the design will hold its temperature the longest. That will mean that your design has the least amount energy transferred outside of the bottle system.

Day 3 TUESDAY: Engineering Design of an insulated bottle -- team designs Learning Target:

I will design a water bottle that limits loss of heat energy by using one insulating material, so I can explain energy transfer as a change to the kinetic energy of particles.

Success Criteria:Predict/rate materials from Most to Least insulatingDiagram with labels the design for the insulated water bottleDescribe energy transfer in n words and pictures

NGSS Lab Lesson Enhancement - Chem. Int. Lesson 5

● The team together determines a design solution to our challenge, that must have:a) Pass your own paper to the right. Now look at your neighbor’s diagram of their design. Get some ideas for the group to use. REPEAT 2x. Choose best diagram to use on your final proposal--or your group could even combine some ideas from a few papers.Sketch the diagram for the final proposal. Label the energy flow in this bottle system.

Label the arrows.What is the water in the bottle touching--where will the hot water thermal energy transfer to?

b) Explanation of the design: Why is the material chosen the best choice for an insulator? What is it about your design that makes you think it will cause your bottle to keep a constant temperature?

c) An energy transfer diagram: Show and explain how energy moves in or out of your bottle system.S how...How does energy transfer from the hot water to the air inside the bottle?

Day 4 THURSDAY: Build and test group design solutions Testing the materials to gain evidence to go with final design decisions -- amount of thermal energy loss, amount of thermal energy gain

Build the agreed upon designTest by recording the temperature every 1 min for 10 minutesDiscuss results as compared to control temperature change and other groups total changeModify design if neededRetest if needed

Day 5 FRIDAY: Scientific Explanation of the design 9

NGSS Lab Lesson Enhancement - Chem. Int. Lesson 5preparing to write a scientistific explanation

class Qualitative and quantitative ranking of materials ● Is it the design or the material that caused it to reduce in temp. the least?

● Which properties of the material made it a better insulator?

● Which aspects of the design made it a better insulator against energy transfer out of the system?

class Philosophical Chairs strategy Cotton Club, Bubble Wrap Camp, etc.

● Prepare to present your claim and give your data ‘For example: Cotton only lost 2 degrees C over 10 minutes compared to aluminum foil that lost 5 degrees in 10 minutes.’

● Give presentation of claim and evidence. Listen to the other groups. Ask questions of the other groups.

● Think...Do you want to change your mind and go to another corner?

1’s Writing prompt: ● Rank the materials 1-9 on their ability to retain heat.

-or--Develop R-value scale after testing materials. The R-value is the difference of the change of temperature over time.

Optional Extension - Not fully developedEvaluate all 4 designs on how they met the criteria, how they fit within the constraints, and how strong was the scientific reasoning about the function of insulators.

NGSS Lab Lesson Enhancement - Chem. Int. Lesson 5

● You (student group) want to start a company that manufactures the best insulating water bottle, you need a grant in order to get the materials for your product.

● Describe and draw your design proposal in order to get the materials to build your product.

○ Include in your proposal a labeled diagram, a description of how it works because of the sleeve material, and an energy transfer diagram to show where energy is moving in your system.

● Why did you choose the materials you chose?● How are you going to build your design?● How/why does your design retain heat the best?

● Why did the hot water lose heat over time?● Why did the container with the lid lose heat energy differently than the container without

the lid?

*Teaching Session:Online simulations - FOSS WebStudents act out molecular motionReading on energy transfer: “Energy on the Move”

Assessment:See supporting documents -

1) Lesson 1 Initial ideas pg 22) Lesson 1 Predictions: ISN insert

Reflection notes - things to consider when teaching the lesson:

Misconceptions:More dense material = more insulatingStudents were looking for materials they know get hot (Ex. sand gets hot)

How did your students engage in the lesson?Structured discussion format, discussion guidelines/norms and sentence stems provided to each group and each student was assigned a # for each students’ turn in the conversation, supported equitable speaking time between group members.

11

NGSS Lab Lesson Enhancement - Chem. Int. Lesson 5

What did the student work and performance in the assessment show about student learning?There was confusion about the design criteria, many groups thought since the water bottle will be tested in an ice water bath that materials would get soaked.

We need a structured method to aid student groups to objectively evaluate individual models to decide which design will be the one the group will pursue. (Ex. each design is rated 0-4 for meeting: 1. design size requirement, 2. ease of construction, 3. waste generated, 4. consumer usability, 5. mass of final product).

They struggled to understand questions about “density” and “particle arrangement,” and how that relates to whether a material is an effective insulator.

What tips would you offer to other teachers?Assign value/cost to materials to force groups to consider a budget in their design of materials used.

Have students predict/rate the order of materials from most to least insulating to allow for reflections once data has been collected.

Considerations

● Supporting all learners – modifications for English Learners, Special Education, Advanced Learners:

● Suggested Unit Adjustments – “Ripple Effects”o Consider: How does the timeline and content of the rest of the unit need to

be adjusted to fit this enhancement? What other lessons need to be dropped or enhanced? Are there specific adjustments to other lessons?

● Integration (optional)o Consider: How does this lesson connect with other content areas,

including CCSS, Math, ELA and 21st Century Skills.o Real World Connections (How does it connect with social, family, and

community happenings?)
