ROCKS AND SOIL
We learnt about all the different layers of soil... then, we made them!
Starting from the very bottom layer, we used broken biscuits for the bedrock.
Marshmallows for the parent material.
Coco pops for the subsoil (with added strawberry lace worms)
and crumbled up cake for the topsoil.
We started Science week by investigating rocks. Testing which are the hardest, which are permeable (allow water to pass through) and which fizz when the make contact with acidic liquids such as vinegar. We were real scientists and made sure each test was fair, making predictions and observations. Even though classroom STUNK of vinegar!!!
