In this activity, learners explore the factors that tend to resist changes in pH of the ocean and why the ocean is becoming more acidic.

This game introduces learners to the scale of the greenhouse gas problem, plus technologies that already exist to dramatically reduce our carbon emissions and prevent climate change.

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.

In this activity, learners design and build a simple wind vane —one of the oldest kinds of weather tools— and use it to show wind direction.

In ancient Chaco Canyon, the people used a "sun dagger" petroglyph to mark the passing of seasons.

Learners follow directions to construct a water-powered electrical generator using a turbine made from plastic spoons.

In this meteorology activity, learners construct simple devices to measure the direction and speed of wind.

In this activity, learners explore how wind tunnels provide feedback to engineers about the performance and durability of products such as planes, cars, and buildings.

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.

In this activity, learners use the Sun's energy to cook marshmallows. Learners construct the solar oven out of simple everyday materials.

The goal of this activity is to design the fastest sailboat or one that carries the most treasure.

In this activity, learners simulate Otto von Guericke's famous Magdeburg Hemispheres experiment.

This activity (on page 2 of the PDF under SciGirls Activity: Earthquakes) is a full inquiry investigation into aerial imagery.

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

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

In this experiment, learners design and build a model room in a shoebox and furnish it with tiny furniture.

In this design challenge activity, learners make a balloon hover at eye level for five seconds, and then make it move by creating air currents.

Experiment with force and pressure by building a balloon rocket. When launched, the balloon will run a track wherever you place the string.

This creative lesson plan provides a visual way for learners to gain knowledge about the finite amount of fresh water on Earth and encourages the discussion of the various ways to conserve this resour

In this activity, learners investigate the food, water, and space needs of common livestock animals.
