(Reminder: Complete Sentences!!)1. What is the science class big goal?2. Why will achieving our big goal help you to live the life you choose for yourself?3. What is one thing you are going to do to make a 3 or 4 on the science EOG this year?4. Make a list (bullets are fine) of everything you know about the word “Density.” If you don’t know anything, take a guess at what you think it might be.

Today’s LEQ: Why is the inside of the Earth divided into layers?

By the end of today, you should be able to…

1. Define Density.2. Explain the difference between objects that are

more dense and objects that are the least dense.3. Identify objects that are more dense and less dense

in comparison to each other.

HOW CAN WE REMEMBER THIS?

• Hotter, Denser, Most Pressure CORE

• Cooler, less dense, less pressure CRUST

• The crust is always LESS of everything!

GROUP PRACTICE Name That Layer!

• With your partner: write down which layer you think the clue is talking about– Yes, you may use your notes!

• When I count to 3, hold up your answer• We are shooting for 100% mastery

Who Am I?

• I am the outermost layer where life exists.

Who Am I?

• I am the layer above the mantle.

Who Am I?

• I am at the center of the Earth

Who Am I?

• I am the coolest layer

Who Am I?

• I am the layer with higher pressure than the outer core

Who Am I?

• I am the LEAST dense layer

Who Am I?

• I am the hottest layer of the earth

Who Am I?

• I am directly below the mantle

Who Am I?

• I am the layer directly above the inner core

Who Am I?

• I am the layer with the highest amount of pressure

Who Am I?

• I am the layer with lower pressure than the mantle

NAME THAT LAYER!

Summarizer: Complete sentences!!1. What is the difference between objects with

HIGH density and objects with LOW density?2. Which layer of the earth is the most dense?

How do you know?3. Which layer of the earth is the least dense?

How do you know?4. Why is the earth separated into layers? Why

do they not all just mix up together?*REMINDER—DO BEHAVIOR AND MASTERY!*
