In Science Class . . . Week of 9/13

This week, we wrapped up our solar system section by reviewing key concepts on the planets (see previous post) and watching a video. We have moved on to discussing evaporation as part of our focus on earth processes. The students observed a demonstration that involved putting two wet paper towels on a scale, with one side being covered by a lid. Key questions:

• Where do you see evaporation in daily life? (When things "dry up" like laundry, puddles on the sidewalk, hair after a shower, etc)
• What did you predict would happen with the scale and the wet paper towels? Would both paper towels dry?
