Today, we investigated different soils to try and work out what they were made of and if they were all the same. Some of us thought it came from the garden centre, others thought it was made from sand. By the end of the lessons, are findings told us that soils are all different and are made from lots of different parts…. we found decaying plants, rocks, sand and even a bone! Finally, we tested the pH of the different soils and found that some soils are more acid, while others are more alkali.
