Making a scale model drawing of
Earth’s layers (“Cheese” or “pie”
Slice!)
• WHY?: The purpose of this is to further
understand the characteristics of Earth layers
(specifically depth) by making a ‘to scale’
model of the Earth.
• This will show the relationships of the layers.
Make a Prediction about Earth’s Layers
•
•
Key:
The slice you have on the handout
represents
Crust =
Brown
a slice of Earth… think pie! Upper Mantle = Red
Lower Mantle = Orange
You will be sketching 4 boundaries
Outer and
Core 5= Yellow
layers.
Inner Core = Grey
• You will be coloring the 5 layers using a key.
• Use a piece of string with a loop to sketch the
ark of the layer, your teacher will demonstrate
in a moment.
Making a Scale Depth model of the Earth: Side 1
1. Complete “Table for
Determining Scaled
Depth of Each Layer”
–
–
–
You and your partner
should calculate each
one separately and then
check your answers
with each other.
You may use a
calculator.
See next slide on how
to complete it!
2. Check answer key 1 to
ensure you calculated
correctly.

Making a Scale Depth model of the Earth: Side 2
1.
Carefully sketch and label the layers on
your “Modeling Earth Layers: A Scaled
Depth…” Handout.

USE A RULER to measure! It’s in cm!
Use pencil so you can erase incase you
made an error.
Check answer key 2 to ensure you drew
and labeled the layers correctly.
Color them the appropriate colors as
indicated on the key and previous table
you completed.
Add information about the lithosphere
and asthenosphere in pencil.
Check answer key 3 to ensure you
included the lithosphere and
Asthenosphere correctly.
Finished? Answer the questions on the
blue handout. You can find it on the front
table.
Key:
Crust = Brown
Upper Mantle = Red
Lower Mantle = Orange
Outer Core = Yellow
Inner Core = Grey

Making a Scale Depth model of the Earth Questions
Read the characteristics of data analysis (flip over). Answer in your lab
notebook. Give your lab notebook an appropriate title and put it in your
table of contents.
1. What characteristic(s) of data analysis does making a to-scale model of
Earth fall under?
2. Explain your reasoning for your answers in questions 1.
3. How might making a to-scale model of inside Earth give us a different
perspective than just looking at numbers of the average depths?
4. Why might scientists make models in the real world (come up with at
least 2 logical reasons)?
5. What is the biggest difference between your predictive model and your
to-scale model?
6. Do you think this difference is a common misconception (do you think
other people made the same error as you)? Explain.
7. Why is it important to fix common misconceptions that exist in science?
8. Now that you have identified this difference, what did you learn from it?
Now, Write a paragraph describing what you learned about the depth of
Earth’s layers.
Characteristics of Data Analysis
DATA ANALYSIS:
1. Do something with the data to help make sense of
it.
2. Account for possible inaccurate data (outliers).
3. Calculate (use math) something.
4. Represent a lot of data with one value
5. Represent the data visually with a model/graph to
get a different perspective.
6. Compare the data with other data (easily).
7. Describe patterns and relationships in the data.
8. Verify the data is accurate.
End of Lesson
Direct vs Indirect observation
• If you look at a cactus, you conclude:
– this is a cactus and it has needles or spines.
– You have observed the needles or spines. Direct.
• You know that needles or spines are sharp.
• If you look at a cactus, you conclude:
– this is a cactus, it has needles or spines, it’s sharp.
– You have observed sharpness/pain!. Indirect.
• In case of direct observations you sense the
phenomenon in question with your sensory organs
directly. In indirect observations, you sense
something intermediate that implies the
phenomenon in question.
• Intermediate obsevations can be many. The more
intermediate things there are, the more careful you
have to be with your conclusions.
Direct vs Indirect observation
• Direct observations involve looking at the actual behavior or
occurrence.
• indirect observations involve looking at a result of that
occurrence.
• For example, if you were interested in seeing how much candy
was given out by a particular neighborhood on Halloween, you
could gather the information in one of the two following ways:
• Direct observation: observe each house and count how many
candies they give out.
Indirect observation: look through trash cans the day after to
see how many empty candy bags are in each trash bin.
• Indirect observation tends to be used when the data cannot be
gathered through direct means, or when gathering the data
through direct observation tends to be too expensive or time
consuming.
