Soil


Yesterday we had a look at our soil.
There are two different kinds of soil, tight and compacted or light and sand like!
To find out what ours was, we got some mud from the garden, put it into a jar and filled it with water.
Now, the less air bubbles that go to the top of the jar the more compacted the mud is.But if a lot of air bubbles go to the top it is light and sand like.
Our soil was tight and compacted, what is yours like?
