In Science Class . . . Week of 11/15

5th Grade: We have been discussing local weather and water systems as we wrap up our earth science unit. The students will have a quiz on Monday, and will be bringing home a completed study guide today.
Key questions:

• Where do our storms come from in CA? (Usually over the Pacific)
• Where does our drinking water come from? (Much of CA depends on rain and snow that falls in the Sierra Nevada mountains. Various water transportation systems bring the water to the coastal areas.)

4th Grade: The students this week learned about fast versus slow geological changes, and we watched a video about volcanoes (which are relatively fast changes to the landscape). They will also have a quiz on Monday on erosion and weathering.
Key questions:

• What are examples of "fast" geological changes? (Volcanoes, earthquakes, landslides)
• What are examples of "slow" geological changes? (Many types of chemical and physical weathering, including freezing water, tree roots, etc)
• What landforms did you learn about? (Meander, plateau, valley, canyon, delta, etc)
