5th Grade: This week in class, we'll be beginning of study of weather by studying weather maps, and then we'll be doing a reading about severe weather conditions. Key questions:
- What symbols did you see on the weather maps, and what do they mean? ( H= high air pressure, L= low air pressure, etc)
- Why does the California coast have more moderate temperatures than inland? (Because we are near the ocean, and the air over the ocean heats up much more slowly because the ocean itself does not heat up easily).
- Where do our storms in Berkeley come from? (Primarily from out over the Pacific Ocean)
4th Grade: We will continue our study of weathering and erosion. The students studied physical weathering last week, and we continued with a review of biological and chemical weathering of rocks early this week. Later in the week, we'll be working with our stream table to observe how water erodes sand and clay. Key questions?
- What do chemical and physical weathering have in common? (Both processes include the break down of rocks into smaller pieces. Physical weather can occur with water, wind, ice, other rocks, while chemical weathering includes a chemical reaction, like with acid rain.)
- What is erosion? (When rocks get carried to new locations)
