Learners build a filter from old soda bottles and dirt. They create polluted water, and pour it through their filter to clean it.

In this design challenge, learners use their creativity and imagination to design and test a wildlife crossing for their favorite animal.

In this activity (on pages 36-39), learners make a model of a watershed out of paper, then run water down the mountain to simulate how rainfall and pollution affect watersheds.

In this activity, learners explore the different salinities of various sources of water by taste-testing.

Learners follow a three-step process to start their own rock collection.

Some aquatic organisms live in open water, while some live in soil at the bottom of a body of water.

In this activity, learners will estimate the sizes of balls to learn how to estimate the size of hail. Learners will compare their estimates to the estimates of their peers and the real measurements.

This marine biology activity (on pages 11-17) introduces learners to kelp (seaweed) forests that grow in the ocean and are home to many species of sea animals.

In this quick activity, learners observe how the added sugar in a can of soda affects its density and thus, its ability to float in water.

In this collecting/comparing activity, learners work with samples of sand from different places like a lakefront, river, or ocean beach.

Learners use M&Ms® (or any other multi-color, equally-sized small candy or pieces) to create a pie graph that expresses the composition of air.

In this environmental education demonstration (page 6 of the PDF), learners will see a tangible representation of the scarcity of soil resources on earth.

Did you know that a Slinky makes a handy model of earthquake waves?

In this activity, learners create models of erosion and floods and learn to recognize both in their environment.

In this activity, learners compare water pressure at different depths. Learners discover that water pressure increases with depth.

In this activity about dinosaurs, learners first participate in a group discussion about where and when dinosaurs lived, how big they were, and who studies them and how.

In this quick activity, learners observe how wind creates ocean currents.

In this outdoor activity, learners use only their senses to to find the extremes of several environmental variables or physical factors: wind, temperature, light, slope and moisture.

This activity (on page 2 of the PDF under SciGirls Activity: Forecasting) is a full inquiry investigation into meteorology and forecasting.

This hands-on experiment will provide learners with an understanding of the issues that surround environmental cleanup.
