3rd and 4th Class conducted an interesting experiment on soil this term. We were investigating the properties of soil and if soil is the same regardless of where it comes from.
We collected a soil sample in a jar, filled it with water and then shook the jar to loosen and mix up the soil. This was then left to settle over a number of weeks and the results were very interesting.
As the photographs show, each soil sample was a different shade of brown (even those taken from the same local area) and was made up of pebbles, clay, silt, heavy organic matter or light organic matter (twigs, grass etc) that we couldn’t see while the soil was dry. By soaking the soil in water, we were able to see the different layers in the jar. We know now that soil is not just dirt!! 🙂
