Surface Tension!

How many drops can a penny hold? -Click on the link to check out the video!



Today we used an eye dropper and looked at shape of a water drop.  It was shaped like a hill.  Then we tried to cut it apart with a toothpick! It wouldn't cut apart and it stayed the same shape. We dropped drops on a penny. Someone discovered if you put drops on the maple leaf side, it held more drops.  The penny took about 25 drops to break over the surface and the water fell over the side of the penny. It was more drops than anyone predicted. The size of the water drop grew on top of the penny.

We had Lego club today for Grade 2s at lunch recess. Trickster Devon was in our room helping us plan a story.
