In this activity, learners interact with a 3-D model of a watershed to better understand the interconnectedness of terrestrial and aquatic environments.

Many people get water from a source deep underground, called groundwater.

When it rains, water can collect on top of and seep into the ground. Water can also run downhill, carrying soil and pollution with it.

Where rainwater goes after the rain stops? And why there are rivers and lakes in some parts of the land but not in others?

How do scientists measure how clear or murky water in a lake is? How does water clarity (clearness) affect what lives in the lake?

In this activity, learners receive a labeled plastic film canister containing a material representing a pollutant (i.e. pencil shavings = a beaver's wood chips).

This activity models some of the ways natural processes, such as erosion and sediment pollution, affect Earth’s landscape.

What is the optimal environment for hatching brine shrimp? Using a scaffold, learners design and conduct experiments testing the effect of a single abiotic factor on brine shrimp cyst hatch rate.
