5th Grade: 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?
4th Grade: This week, the students broke apart their fake rocks and separated based on "minerals." We then put the gray material in water to separate in further. The second class of the week, students observed real mineral samples and recorded observations.
- What types of minerals did you find in the fake rocks? (Blue, red, white, and gray, the last of which we were able to separate further and appeared in layers in our vials filled with water.)
- What were some of the words you used to describe the mineral samples? (Rough, smooth, shiny, dull, transparent, green, white, etc)
