This week we started exploring soil. We performed a lab where we separated soil out into its 4 main components; small rocks, gravel, sand, and silt. We then predicted which “ingredient” would be the heaviest, weighed out each, and created a graph comparing the results. Below are photos of the lab in action, the 4 soil components, some written observations/ directions, and a student graph of thier group findings! Please feel free to leave your comments…
