We made edible soil so we could show the soil layers. We made this in a clear plastic cup. We used an an oreo cookie to show this bottom layer which is called the bedrock. Next we added cocopops and M&Ms to show the parent material or substratum layer. We made chocolate mousse and then added that to show the next layer which is subsoil. We crushed digestive biscuits (showing how weathering and pressure work to break up rocks) and added this to represent the top soil. We add organic matter (humus) last of all. For this we used chocolate chips. After we completed our assessments we ate it! YUM YUM.
