1. Bell Ringer: Science/ Density
On Page 1 of your notes:
1. If you were trying to dig a hole to China, do
you think you would be able to? Why or why
not?
2. Compare this apple slice to the interior of the
Earth. How does each layer of the apple
correspond to each layer of the Earth?

2. 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.

3. What do we call this?

4. What do we call this?

5. The Earth has 4 Separate Layers…
WHY????

6. 1. Testable Question:
• Why does Earth’s inside separate into
layers? Why aren’t they all mixed up?

7. 2. Background Information
• What do you think the inside of the
earth looks like?

8. 2. Background Information
• Density = mass / volume
• Density is the science word for heavy.
• More dense materials sink
• Less dense materials float
• Gravity pulls ____________________.

9. Daily Vocabulary:
Use your book to define the word and
Make a Word Web for each word:
Density
Inner Core
Outer Core
Mantle
Crust

10. Density

11. Inner Core

12. Outer core

13. Mantle

14. Crust

15. Experiment- Page 3 in your
notes
• Density Lab
• Explore how density affects the
layers of the Earth
– Time management
– Follow procedures
– Clean up

16. Research/Background
Information
Layer Temperature Density Features
Inner
Core
Outer
Core
Mantle
Crust

17. Synthesize this Information…
Turn to your partner and complete:
• Density is _____
• ______ dense materials sink
• ______ dense materials float

18. Hypothesis
• Page 2 in your notes- label it Density
experiment
• I predict that Earth’s inside separates
into layers because:
________________________________

19. Gather Data
• Draw and label what your graduated
cylinder looks like. (Make sure you
label each liquid)

20. Analyze Data
• Why did the syrup sink to the bottom?
• Why did the oil float on top?
• Make an analogy comparing your
density column to the layers of the
earth.
– Ex: The syrup is like the inner core
because it is the most dense layer.

21. Write Time! What did we learn?
• Draw a cross section of the inside of the
earth and label each layer.
• If you were trying to dig a hole to
China, do you think you would be able
to? Why or why not?
• Why does Earth’s inside separate into
layers? Why aren’t they all mixed up?

22. Apply what you’ve learned!

Iron 5.3 Layer B
Lead 12.1 Layer C
Layer D
Marble 2.4
Phosphor 8.7
