Last week, we learned about trees, leaves, and soil. We did two experiements:
1) We read about trees and how to determine their age, their benefit to our lives, the difference between a deciduous and evergreen tree, and the parts of a leaf.
2) We looked at the parts of soil. We gathered some soil and added water. We recorded what it looked like at the beginning, then after 24 hours. the tiny pieces at the top are called humus (rotted plants), then the layer is typically water, clay, sand, and stones. We were surprised to discover that our water stayed murky after 24 hours, unlike the experiment we watched on the ‘Discover and Do’ DVD.
