In this environmental science activity (page 3 of the PDF), leaners will identify and explain the causes of erosion.

In this drawing/mapping activity, learners design plots of land while incorporating positive strategies for improving water quality.

Learners design their own experiment to explore the permeability of different materials such as soil, sand, gravel, and marbles.

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

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

Learners draw comic-style pictures to show the water cycle. From a starting picture, one learner draws what happens to the water in the next panel, then passes the comic strip to another learner.

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).

In this investigation, learners plant seeds in a 2-liter bottle filled with soil that is connected to a water source below. Over the next few weeks, learners observe how the plants grow.

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.

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

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

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.

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

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.
