This picture is highlighting the importance of disposing of trash correctly, because it is prone to get into our water systems killing our fish and essentially polluting the water we drink and shower in. By correctly getting rid of technological waste it will save us from a world of toxins entering the environment.
This little observation activity is great for lower elementary students. They compare water with and without trash in it. Children get up close and personal with how abandoned trash can pollute our water.
This is a simple but very effective experiment to help children to see one of the differences between fresh and salt water. With a few materials they will understand why objects are more buoyant in salt water. You will receive complete instructions with complementary photos, as well as a response page for students.This is part of a larger Sea Creatures unit that you can access here:Sea Creatures Integrated Unit
