We Examine the Differences & Similarities of Sand and Humus

We Work Together to Make Observations

Packing a Cup to Create a Sand Castle

We Will Record How Wind & Water Erode the Sand Castle

Humus Doesn't Stick Together as Well as Sand!

Will Wind & Water Erode Our "Humus Castle"?

Our Young Scientists Are Eager to Experiment!

Water Droplets Erode the Humus!

Observe Carefully...

Eventually We Create a Stream Table & the Sand Will be the Model for our Earth's Soil
