Plate Tectonic 
THIRD GRADE
4 week unit

1. Students should be able to distinguish several different volcanic rocks. They should be able to conclude that volcanoes produce different types of rocks that reflect the type of volcanic eruption that produced them.
2. Students should have developed observational skills to distinguish different types of rocks.
3. Students should begin to develop an understanding that earthquakes and volcanoes are related.
4. Students should be able to conclude that stress within the outer surface of the Earth causes the Earth to move, hence creating earthquakes.
5. Students should be able to demonstrate different types of motion that can create stress on the outer surface of the Earth. They should demonstrate diverging, converging and transform motion.
6. Students should be able to distinguish the ability of some substances to resist stress, while distinguishing some substance to crumble under stress.
7. Students should realize that volcanoes can be a hazard to humans, property, and wildlife.
8. Students should be able to visualize that volcanic disasters have occurred through historical times.

WEEK 1.
PRE: Explaining why there are many types of volcanic rocks.
LAB: Comparing rocks from different volcanoes.
POST: Learning that volcanoes produce different types of rocks.

EARTHQUAKES

WEEK 2.
