Composition of Soil - Experiment Two
Children will take a closer look at the different things that make up soil while working with science tools like hand lenses. They will also practice the skills of observing and recording data in this continuation of the previous experiment.
Jars filled with soil from the previous day
White bulletin board paper to cover the tables with
Hand lenses, one per child
Paper or science notebooks
Pencils, crayons, markers
Cover the work surfaces with large sheets of white paper. This will make up easier and give the children a clear surface to work on.
Give each of the groups a jar of soil, a few plastic spoons and hand lenses. Show them how to carefully pour out their soil onto the white paper. Then have them use the spoon to separate the things they find in the soil and the hand lenses to take a closer look at the sediments in the soil. Once again talk about what they notice.
What kinds of things can they see in their soil?
Are there different types or colors of soil?
When they use the hand lenses, can they see different-sized particles?
Did they find sand, rocks, gravel, or clay?
As an assessment have the children draw or write in their science notebooks or on plain paper what they learned about the composition of soil. Some may be able identify a few things that make up soil, while others will be able to explain how the soil settled and why.
