Antarctic Antics

my caterpillar collectionCaterpillar catchers were on the hunt, scouring every tree trunk, log, table, fence post, and friend for the fourteen legged creepy crawlers.  Trillions of tent moth caterpillars, as estimated by the sharp-eyed collectors, were discovered and well cared for.

adding food coloring to our ice bergsThe following day the early students mixed up some ocean water by measuring out cups of water and stirring in teaspoonfuls of salt.  During morning-meeting we took out the frozen sea ice and ice bergs and observed what happened when they were placed in our ocean water.  We marked the water line when the sea ice was added, then observed what happened when we added the ice bergs.  The children observed that the sea ice melted much faster than the ice bergs.  They observed that the sea ice floated with the top of the ice aligning with the top of the water, while the ice bergs floated with a small portion above the water line, and a larger portion below the water line.  We observed that when we added the ice bergs, the water line rose.  At the end of the morning the ice bergs and sea ice were all melted.  So we discovered that all of our hypotheses were accurate – the ice did melt in the water, it both sank and floated, and the water did expand when it froze.  During circle-time we watched a video clip of a glacier calving.  It was hard to get the proper perspective of their truly enormous size, but it was neat to watch the giant chunks of ice break off and plunge into the water then shoot back up.
