The History of the Earth: Supplemental Guide 3A | The Earth Inside-Out, Part II 63
- Inferential Why is it important for scientists to study volcanoes
and keep people informed about them? (It is important for
scientists to study volcanoes so they can learn more about
them and help keep people safe from geological disasters.)
[Please continue to model the Think Pair Share process for
students, as necessary, and scaffold students in their use of the
process.]
I am going to ask a question. I will give you a minute to think about
the question, and then I will ask you to turn to your neighbor and
discuss the question. Finally, I will call on several of you to share
what you discussed with your partner. - Evaluative Think Pair Share: How are the crust, mantle, and
core of the earth alike? (They are all layers of the earth and
they all contain rock.) How are they different? (The crust,
mantle, and core are different because some parts are solid
and some parts are liquid. The crust, mantle, and core are
also different because some parts are hotter than others.) - After hearing today’s read-aloud and questions and answers,
do you have any remaining questions? [If time permits, you
may wish to allow for individual, group, or class research of
the text and/or other resources to answer these questions.]
Word Work: Solid 5 minutes
- In the read-aloud you heard, “Heat closer to the core causes
the rock inside the mantle to move around quite a bit. But in
most places, it is still solid rather than liquid.” - Say the word solid with me.
- If something is solid, it keeps its shape.
- It was so cold outside last night that the water puddle became
solid ice. - What things have you seen that are solid? Try to use the word
solid when you tell about it. [Ask two or three students. If
necessary, guide and/or rephrase the students’ responses:
“ is solid.”] - What’s the word we’ve been talking about?
