Soil testing

I remember picking my son up from school one day and a parent next to me saying ’Oh no, your child has had a terrible accident!’. To be honest, I could not see anything wrong! He was just covered in mud. The reason? he had been lying in the soft mulch making dirt angels. Dirt is fascinating. Why not look at the different soils you can find on a walk or in the garden? Describe them with your senses.
