In this activity, learners simulate nature's water filtration system by devising a system that will filter out both visible and invisible pollutants from water.

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.

Why is ocean water sometimes the warmest when the average daily air temperature starts to drop? In this activity, learners explore the differing heat capacities of water and air using real data.

Water, whether fresh or salty, serves as one of the best electrical conductors on the planet. Does salt effect its conductivity?

In this activity, learners visualize the differences in water density and relate this to the potential consequences of increased glacial melting.

Learners work in teams to design and build solar water heating devices that mimic those used in residences to capture energy in the form of solar radiation and convert it to thermal energy.

In this activity, learners explore the concept of density-driven currents (thermohaline circulation) and how these currents are affected by climate change.

In this sunny day experiment, learners measure and compare how quickly light and dark colored materials absorb heat.

In this activity, learners use simple items to construct a device for indicating air pressure changes.

In this activity (page 1 of the PDF under SciGirls Activity: Bogs), learners will test cups full of potting soil, sand, and sphagnum moss to see which earth material is able to soak up the most water.

In this activity, learners practice the steps involved in a scientific investigation while learning why ice formations on land (not those on water) will cause a rise in sea level upon melting.

This online simulation game explores the different consequences of water levels on the Columbia River in the Pacific Northwest.

April showers bring May flowers, but what do coastal storms bring?

In this activity, learners make a model of a pollution spill that occurred at Bangs Lake in Mississippi and measure water quality parameters in their model.

In this environmental science and data analysis activity, learners work in groups to track a Dead Zone (decreased dissolved oxygen content of a body of water) using water quality data from the Nutrien

“Exploring Earth: Rising Sea” is a hands-on activity demonstrating ways to use topographical mapping techniques to track changes in sea level. The activity is connected to current NASA research.

Learners build models of sinkholes to gain an intuitive knowledge of their physical aspects.

In this activity, learners use rice grains to model the composition of the atmosphere of the Earth today and in 1880. Learners assemble the model while measuring percentages.

In this activity, learners explore clouds and how they form.

In this activity, learners construct hand-held altitude trackers. The device is a sighting tube with a marked water level that permits measurement of the inclination of the tube.
