Trash Timeline

Students worked together to create hypotheses about how long different items, like glass, plastic, and aluminum, take to decompose. 

Impervious vs. Pervious Surfaces

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

Making a Watershed Simulation

A watershed is all the land and waterways in a certain area. Students examined, through a simulation and discussion, how pollutants can travel through the watershed and end up in our rivers and oceans. To simulate a watershed, and the effects of rain on the watershed, we used paper, markers, and small particles, like seasoning and sprinkles.
