Through making observations of mixing various items with water, students develop ideas about how pollution happens. The cumulative effect of what happens when many people add only “a little something” to the water provides students with a concrete representation of what can happen in their own communities. Students complete the lesson by determining what they can do to prevent pollution from happening in their own communities. This activity promotes National Science Education Content Standards A, B, and F, and Iowa Teaching Standards 1, 2, 3, 4, 5, and 6.
