Daffy Density
Source Institutions
In this chemistry activity, learners explore density by using four solids and 6 liquids to create colorful, layered rows.
Why Are Two Eyes Better Than One?
Source Institutions
In this activity, learners explore how their depth perception would be affected if they only had one eye. Learners work in pairs and attempt to drop a penny in a cup with one eye covered.

Storm Water Runoff Pollution
Source Institutions
This activity (located on page 8 of the PDF) introduces learners to the concept of Non-point Source Pollution--what happens when rain washes garbage and other pollutants into rivers and lakes.
