Shake, Rattle, and Roll

How do rocks change in moving water?
On November 19th, Team Gibbas students explored how rocks change in moving water by conducting an inquiry activity on weathering called "Shake, Rattle, and Roll."  Students were given sandstone, water, and three plastic containers.  Students were instructed to shake one container for two minutes, one container for five minutes, and to let one container rest.  Then, students made observations about what the rocks looked like.

Students observed that after shaking the rocks appeared to be smaller and smoother.  And the container that was shaken for five minutes had sand on the bottom!
