Learning Goals: We are learning about what soil is and why it is important.
Success Criteria: We know that soil is made from broken down rocks.
Success Criteria: We know that soil is composed of 4 elements:
- minerals and rocks
- organic matter (humus)
Success Criteria: We know that there are 4 types of soil: (video above only shows 3)

When separating soil, the bottom layer will be the sand part of the soil because sand particles are the largest and weigh the most.
The next part is the silt layer. Silt particles are smaller than sand and weigh less so they will appear over the sand.
The clay particles will be the smallest and will be on top. At the top of the jar will be organic material which isn’t fully rotted.
