Water Filter Experiment

Today we did a water filter experiment. Alana and I were partners. First we got our containers. One had a hole and the other didn't. Next we had a choice of bark, sand, cotton balls and paper towels to use as our filters. We had to test the filters individually so we can see which are the best to use for our competition filter. Alana and I chose paper towels and cotton balls, it worked okay because it got all the dirt out but it still was a bit discoloured.
