We learnt that soil was made up of 4 layers: bedrock, rocky soil, subsoil and topsoil. Then we went out and dug up some soil to find out what was in it. We saw leaves, twigs, roots, spiders, woodlice and many more creepy-crawlies! After that, we made our own compost and learnt about the important jobs worms do in our soil. We even held some worms!
