We conducted a soil experiment today after learning about the layers of the soil. In the containers above we had the substances of clay, sand, and humus soil. We drew the layers in our science journals and discussed how the bedrock is the bottom layer, with subsoil on top of that. Then we have top soil and humus. Humus is made of decaying plants and animals and contains lots of nutrients for the plants to grow. We discussed which type of substance would be the best to grow plants.
Next week, we are going to create edible layers to eat with worms (gummy, of course)!
