I need help! You're in a town called Watertown. You need to save it from water pollution. They don't have any money! SO, they need you to use stuff from your house (imagine). Make a design that shows how to stop it from happening. How could you clean the water in your model using the materials around the house?

PLEASE HELP ME! I NEED HELP!! IF YOU GOT ONE, MAKE A QUESTION AND ILL GIVE YOU ALL MY POINTS.

You can clean the water pollution by the water bottle activity.

Explanation:

You can do the water bottle filteration. From your house, you should find a large soda bottle or water bottle. YOu layer it with sand and gravel at the bottom. Line the top of the bottle with a coffee filter. This will allow for a natural filtration system.

You can find this on many science experiments websites because it is a common science fair project.
