Trash Timeline

Students work together to create hypothesis about how long different items take to naturally decompose. 

Impervious Surfaces

Through a hands-on activity, students demonstrate how water flows over pervious and impervious surfaces, mimicking the flow of stormwater runoff here in D.C.

Making a Watershed Simulation

A watershed is all the land and waterways in a certain area. Students were able to examine how pollutants can travel through the watershed and end up in our rives and oceans by using paper, markers, and small particles like seasoning and sprinkles to stimulate a storm's impact on a watershed.
