Below you will see our young scientists exploring the effects of weathering by break rock down into itty particles of dust.  We used sandpaper to represent sand along the beach or water smoothing out a stone in a creek.  We also created mini glaciers, watching how they change the surface of the land as it passed on through and then once more adding more friction to the surface.  The clumped sand you see left behind from our glaciers is called moraine, a fancy word for rock debris.  It a grain of sand were to be left all by its lonesome, then that is an erratic.  However most erratics look like this . . .

The torn tin foil (our ground) is now carved into valleys and mountains.  Students finished by creating illustrations of the activity and labeling the parts mentioned above, as well as the terminus (the end of a glacier).  We’ll continue with how glaciers move tomorrow and hopefully get into some volcanic activity if we’re lucky.
