Biology: 10,000 Microns under the Sea

This week the kids hunted for microorganisms in a sample of pond water taken from Robert and Karen Clements' pond (thanks once again for your annual donation of pond scum!).

The kids turned up some interesting single-celled organisms and even a worm or two. Believe me when I tell you, these 2 mm guys are pretty alarming swimming around eating algae magnified 100x!

The kids used what they learned last week to estimate the sizes of the different organisms.
