Teach Engineering: Soapy Stress
To experience the three types of material stress related to rocks - tensional, compressional and shear - students break bars of soap using only their hands. They apply force created by the muscles in their own hands to put pressure on...

Serc: Modeling Glacier Dynamics With Flubber
This hands-on activity describes glacier mass balance in a changing climate. Students make a glacier, construct a glacier valley, then run several tests with different values for valley slope, "flubber" temperature, and basal conditions...
