Part 1:
1. Go to the following website: http://www.learner.org/interactives/rockcycle/index.html
2. Click on “Begin with Types of Rocks.” Read over the description of Igneous, Metamorphic and Sedimentary rocks. Then scroll to the bottom and examine the “What to look for” chart.
3. Write down the six clues below (they are in red):
a) ___________
b) ___________
c) ___________
d) ___________
e) ___________
f) ___________
4. Then click “Next: Start your collection.” Click Begin. Click on each of the six rocks to identify them and read a brief description.
Name of Rock Share two facts about this rock! Igneous, Metamorphic or Sedimentary?
(Do your best to use your knowledge to classify each rock!)
a) _________ __________________________ _________________________________
b) _________ __________________________ _________________________________
c) _________ __________________________ _________________________________
d) _________ __________________________ _________________________________
e) _________ __________________________ _________________________________
f) _________ __________________________ _________________________________
5. Now click “Next: Identify Rock Types” and read the directions on how to play.
Characteristic Type of Rock (circle one)
a) ___________________________ Igneous Metamorphic Sedimentary
b) ___________________________ Igneous Metamorphic Sedimentary
c) ___________________________ Igneous Metamorphic Sedimentary
d) ___________________________ Igneous Metamorphic Sedimentary
e) ___________________________ Igneous Metamorphic Sedimentary
6. Now click on the next chapter, titled “How Rocks Change.” Read the section on how heat and pressure changes rocks and watch the animation by clicking Start.
a) Heat and pressure causes _______________ rock to turn into ______________ rock.
7. Click “Next.” Read the section on Heating and Cooling. Click on the animation for Melting.
a) Melting causes _______________ rock to turn into ______________.
8. Click on the animation for Cooling. You may need to replay the animation more than once to answer the following questions.
a) How does extrusive igneous rock form? _____________________________________________________.
b) How does intrusive igneous rock form? _____________________________________________________.
c) Which cools faster? __________________
d) Which has crystals? __________________
9. Click “Next.” Read the section on Weathering and Erosion and Compacting and Cementing. Watch both animations. Take notes from animations in the space provided.
Weathering and Erosion:
Compacting and Cementing:
10. Click on “Transform the Rock.” Read the directions for how to play and press “Begin.” IMPORTANT: Fill out the table (column 1 and column 3) below BEFORE submitting each answer. The words disappear very quickly!
a) _______________________ + _____________________ = _______________
b) _______________________ + _____________________ = _______________
c) _______________________ + _____________________ = _______________
d) _______________________ + _____________________ = _______________
e) _______________________ + _____________________ = _______________
f) _______________________ + _____________________ = _______________
g) _______________________ + _____________________ = _______________
h) _______________________ + _____________________ = _______________
i) _______________________ + _____________________ = _______________
11. Go onto the next chapter. Explore the rock cycle diagram. When ready, click the Next to “Complete the Cycle!” Read the directions to learn how to play. You do not have to write your answers down, the computer will score you.
12. After completing the diagram you are ready to test your skills. Click Begin. Final score ____ / 15.
