Making paper - easy, fun, and memorable
This is easily one of my favorite experiments. It makes a huge mess, but everyone will learn something. You start with a great environment - clean water, sand, plants, rocks, shells, animals. This is ideal.
Oh no! There was an oil spill in the water. It's all over everything. It doesn't stay in the water - it seeps into the sand and touches everything. How are they going to clean it up???
I don't have any more photos of this experiment because it gets so messy the camera wasn't a priority. I gave them a variety of materials - cotton, pantyhose, dish detergent, kitty litter, nets, etc. I also let them use anything (within reason) they thought might help. Remember anything being used will end up with oil on it.
The cotton soaks up the water and oil. The pantyhose attracts the oil to it, but doesn't clean it. The dish detergent takes it off animals and plants, but leaves it in the water. The kitty litter soaks up the oil the best, but can't be contained. The nets don't do anything. The best solution is a combination. Put kitty litter inside the pantyhose for the best solution. The biggest take away is it's best not to make the planet dirty in the first place.
