Plankton Wars :)

Our assignment was to create plankton with the materials given, paper, clay, pebbles, cups, etc.. My partner, Chris, and I made a umbrella looking plankton. We had to use the clay, so we wrapped it around a piece of straw so it would be hollow. Hoping this would make it buoyant. we attached a small pebble to the bottom because our teacher told us the problem most kids make is to make it too buoyant. Last we put a sponge and a cupcake holder on top. The cupcake holder was to catch the water and give resistance allowing it more floating time. Sadly though we lost :( once the cupcake holder got wet it gave way to the pebble and sank with speed. The winners had won because they balanced the weight out enough to sink yet float, which was the goal.
