Think about the structure of the Earth Get started:

With a partner, you will be assigned one of the geologic events pictured on pages 61 & 62 and answer the following questions on a separate sheet of paper to turn in.

What changes occurred in the area you selected? Changes might be large or small. You might notice the size, shape or position of parts of the area may have changed. Describe each of these changes

What evidence do you see in the photographs that might indicate earth’s surface is not one continuous piece?

** You and your partner will be graded on your answers so you must be VERY DETAILED!

Conference

Now meet with other people who observed the same picture as you do. Share what you observed.

Take notes on your group discussion on the sheet of paper to be turned in.

2.2 Vocabulary

Crust: the outermost layer of earth, composed of rock. Plates: sheets of rock that include part of Earth’s crust Plate tectonics: the theory that Earth’s crust is divided

into a number of plates, and the study of how the plates move and interact with one another

Mantle: the zone of earth beneath the crust and above the core. It is divided into the upper mantle and the lower mantle

Core: the central part of Earth made of iron and nickel. It consists of a liquid outer core and solid inner core.

Answer in complete sentences Finish with reading ‘What’s the point?’

Brainstorm

Think of a better way to represent the Earth’s structure than Benny’s Egg model. Be descriptive and explain what each layer would be.

Write a letter back to Benny describing the earth layers in your model.

Quiz

You have five minutes to study for your quiz on Earth Layers. Sit quietly and study your earth diagram and Reading guide you did last class.

Density Lab You will be placed in groups of 4-6 students. Follow all

directions for the lab and wear safety goggles while working on the activity. Fill out your density lab worksheet and answer questions 1-6 on the back to be turned in for a class grade. Each member of the group will have one job title. If anyone does not follow these guidelines, they will be asked not to participate. Group Manager Reader Supplies gatherer Safety coordinator Cleanup

Warm Up 3.17 & 3.18

Explain why you think the Earth’s plates move and cause geologic activity? Answer in 2-3 COMPLETE sentences.

Lab Questions

Finish answering questions 1-6 on pages 81 & 82 on your density lab. We will go over these in class. You will be turning in your lab worksheet for class grade so make sure they are complete sentences!

Earth Systems

Atmosphere: the part of Earth’s system made of the mixture of gases that surround Earth.

Biosphere: The part of Earth’s system that includes all living organisms (animals and plants) and also dead and decaying plant matter. Includes parts of the lithosphere, hydrosphere and

atmosphere.

Hydrosphere: the part of Earth’s system that includes all of the plant’s water, including oceans, lakes, rivers, ground water, ice and water vapor.

Geosphere: The part of earth’s system that includes the crust, mantle, and inner and outer core.

Cracking Up

Read the article ‘Cracking Up’ and answer the questions on the worksheet for a grade.

Reminder

All late work and retakes must be done by March 26th in order to be considered for a grade for 3rd quarter. Notebook checks will be next week! Make sure everything is glued or taped in!

Cracking Up

If you have not finished the ‘Cracking up’ reading and worksheet you have fifteen minutes to do so now. It must be turned in by the end of the class. It counts as a classwork grade.

Lab Activity

You will work in partners with the person sitting next to you at your desk. You MUST follow the Procedure for this lab on page 93. You will be given a worksheet to fill out while doing this lab. When you have finished cleaning up after the lab answer REFLECT questions 1-3 on page 95. You can answer those questions on the back of the worksheet.
