In Undoing Pollution, you'll learn how the effects of pollution are very difficult to erase. One of the most common forms is water pollution. In this activity, you'll have a chance to contaminate some water and then try to get rid of the pollution with different tools and devices.

What You'll Need:

  • Bucket
  • Water Pollutants (dirt, oil, trash)
  • Tongs
  • Strainer

Step 1: Fill a five-gallon bucket with clean water.

Step 2: Now, do your best to pollute the water. Throw in dirt, gravel, vegetable oil (to stand for toxic oil spills), trash (plastic packaging and any other kind of trash you've seen polluting water in nature), and other kinds of pollution. Yuck!

Step 3: Now, here's the hard part: What can you do to un-pollute the water? You can use tongs, strainers, and anything else you can think of. Can you get the water really clean again?
