Homemade Soil
Yesterday, we made homemade soil. We added pebbles, gravel, sand and silt. We also found out what humus was. Humas is made up of decayed plants and animals. Humus is in soil too! Today we separated our soil with screens, but we were left with a container that had a sand mixture in it. We put it into a vial, added water and we were able to separate it into different layers containing the humus, silt and sand. It was so cool!
Surprise! Thank You Mrs. Kershasky!

Screening River Rocks
Today in Science, we explored different ways to separate a river rock mixture. At first, we used our hands, but then we used screens. We found out that if a rock was too large to go through a screen, it stayed on top of the screen. We were able to use three different screens. We are so excited to do more separating later in the week.
