Day 8
What are the three types of rock?
igneous, metamorphic & sedimentary
What's the major difference between the
three types?
The major difference is in how they
form.

Temperature
Rate of cooling
Length of time in hot water
The way the bottle lies as it cools
Create a data table to represent both
variables that you are testing.

Crystal Size Investigation
Procedure:
1. Each group will get 2 bottles of salol.
2. Place both bottles in hot water to melt.
3. Place one bottle on its side in ice water
and the other bottle on its side in room
temperature water.
4. Observe and record every 30 seconds.
5. Compare the crystals in the two bottles
when all the material has crystallized.

Day 10
What forces are constantly shaping and
reshaping Earth’s surface? (Hint:
constructive/ destructive)
Earth processes are going all the time.
Destructive processes break down
landforms. These include weathering,
erosion, and tectonic plates sinking and
melting. Constructive processes build
up. They include mountain building,
deposition (sedimentation), and new
crust formation.
