Learners investigate the concept of humidity by using a dry and wet sponge as a model. They determine a model for 100% humidity, a sponge saturated with water.

This is an activity that models the operation of a seismograph, a tool used to measure the size of earthquakes.

Discover the wind's direction using bubbles, a map and a keen eye. Learners blow bubbles and note their general direction on a map, taking readings from different points around a building.

In this group activity, learners use some common objects and work together to simulate the Coriolis effect. During the challenge, learners make predictions and test different scenarios.

This activity has three story puzzles learners can solve to learn about life in the Arctic.

In this quick activity (page 2 of PDF under GPS: Lava Flow Activity), learners will model how large depressions near the top of a volcano are formed by using an inflating and deflating balloon submerg

In this activity, learners construct hail-proof houses using recycled materials to discuss storm readiness and safety.

In this activity, learners explore density, convection, stratification, and, by inference, the melting of icebergs. Learners make hypotheses, test their hypotheses, and explain their observations.

In this activity, learners will engineer three different parachutes to test how well each one works.

In this activity, learners gain knowledge about how carbon moves through all four of the Earth’s major spheres (biosphere, hydrosphere, atmosphere, and lithosphere), and understand how humans influenc

In this activity, learners graph 48 hourly air temperatures from a local weather observation site and observe the diurnal temperature variations.

In this activity, learners observe how salinity affects the freezing point of water by making and enjoying ice cream.

In this activity (page 1 of PDF under SciGirls Activity: Forecasting), learners will construct an air cannon by cutting a hole in the bottom of a bucket and stretching a garbage bag over the other end

In this weather forecasting activity, learners use common materials to construct a rain gauge and measure daily, monthly, and yearly rainfall.

In this activity, learners explore how the shapes, sizes, and distances of land masses appear differently on two different models of Earth: an icosahedron and a flat map.

In this activity (page 2 of PDF under GPS: Cave Swallows Activity), learners will model how caves are formed by placing one piece of chalk in a cup of vinegar and another piece in a cup of water, then

In this activity, learners create their own weather forecast map.

Water on Earth is in lakes, the ocean, rivers, underground, and frozen glaciers.

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 physics activity (page 8-9 of the PDF), learners will explore wind energy. They will build their own windmill and see how energy from wind can be converted into a useable form.
