Lithosphere and Asthenosphere Caramel Lab
In your Science Journal in the front Labs section write the following title:
Lithosphere and Asthenosphere Caramel Lab
Answer the following questions.
1) Define (in your own words) the following
vocabulary.
a. Brittle
b. Ductile
c. Asthenosphere
d. Lithosphere
2) Which part of the mantle (lithosphere or asthenosphere) is considered brittle?
3) Which part of the mantle (lithosphere or asthenosphere) is considered ductile?
4) Discuss with your group possible answer to the following question. You do not
need to write answers down but you can if you want.
What make the lithosphere and asthenosphere have different hardness?
When Ms. H tells you to, complete the following activity.
1)
2)
3)
4)
5)
6)
7)
Put on safety goggles.
Get a hammer, mat, and a piece of the “cold caramel.”
Made a quick before sketch of your caramel in your science journal.
Warn others around you! This is important!
Hit the cold caramel with a moderate amount of force.
Record observations and an after drawing of your caramel.
Clean up all pieces of the caramel and throw them in the trash.
8) Keep your safety goggles on!
9) Now get a piece of the “warm caramel.”
10)Make a quick before sketch of your caramel in your science journal.
11)Warn others around you! This is important!
12)Hit the warm caramel with a moderate amount of force.
13)Record observations and an after drawing of your caramel.
14)Clean up all pieces of the caramel and throw them in the trash.
Answer the following questions in your science journal.
1)
2)
3)
4)
5)
Which caramel was brittle?
Which caramel was ductile?
Which caramel behaved like the lithosphere?
Which caramel behaved like the asthenosphere?
Based on this activity, what is one factor that contributes the do the
difference in the hardness of the lithosphere and the asthenosphere?
Mantle Convection Lab
In your Science Journal in the front Labs section write
the following title:
Mantle Convection Lab
Answer the following questions.
1) Define Convection Current in your own words.
This is tough so do your best.
2) Define plate as it relates to Earth science.
3) Where does most of Earth’s heat come from? (See
page 17 in the Inside Earth volcano book.)
4) Turn to page 37 in your Inside Earth volcano book
and read the activity.
Put on your safety goggles.
When Ms. H tells you to, complete the Skills Lab.
1) Discuss with your group members the answers to the Analyze and Conclude
questions.
2) In your science journal make a sketch of the model that you just made. Show as
much detail as you can. Make sure to label the parts of your model and include
what they represent, like mantle and plates.
3) Answer the Communicating question #5 in your science journal.
