1. Energy & the Rock Cycle
SINKHOLES

2. Class Agenda TODAY’s PLAN: Today’s TaSK:
EQ: What source of energy drives the rock cycle? LT: Develop and use models to obtain information about the rock cycle SC: To identify the 2 factors (Variables) that cause rock changes
Prepare to complete the energy transfer rock cycle lab

3. INITIAL THOUGHTS Is there one path through the rock cycle? Explain…
What are the two main factors (Variables) that cause rocks to melt?
How do you think energy plays a role in this process?

4. Write a hypothesis for rocks…
Using your current experience with rocks, Predict what 2 factors are required to cause changes to rocks: (On Worksheet) In order for a rock to change, it must _______________________________________ and _____________________________________________.

5. Rock Cycle Model
Below your hypothesis, draw a new model of the rock cycle as you currently understand it.
Remember our rules for models? (Use your notes to help you)

6. Energy and the rock cycle

7. slowly
energy
thousands to millions

8. Heat Earth was once a molten ball of rock.
The earth’s interior still contains molten rock and metal.
Heat inside the earth causes rocks to melt partially or completely.

9. Pressure
As sediments pile up they put pressure on lower sediments and smash them together to make sedimentary rocks.
Near sinkholes, there are certain types of sedimentary rocks.

10. Did your model include energy, heat & pressure?
Self Check
Did your model include energy, heat & pressure?
Did it show the flow of energy?

11. Class Discussion: Review from Rock Bio Research
Who are the rock experts in the room?
Who has played the rock cycle game, completed the Actively Learns and completed their rock biography?
What is the rock cycle?
Why is it important?
Why do rocks look so different?

12. Watch these videos to prepare
Chocolate Rock Cycle Link (1:14)
Candy Rock Cycle Video Link (8:35)

13. After writing your hypothesis… Read the materials list & procedures on the next slides
Answer these questions in your notebook to help you prepare:
What questions do you have?
Do you understand what the materials are?
What type of data are we collecting? Why aren’t we using units?

14. REVIEW: Materials 1. Look over the matching list on your table.
2. Is there any materials you are not familiar with?
3. What will be important safety precautions tomorrow?

15. REVIEW: ProcedureS
Read part 1 of the procedures and identify with your team which materials you will need for that part. (Make sure to ask questions now)
Repeat for Parts 2-5
REMEMBER: The less questions you ask me tomorrow, the better your score

16. Complete your Middle check and answer the Revised Thoughts
What was surprising?
What did you already know but see in a new way?
What do you still need help with?
