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 activity, learners experiment and observe how the color of materials that cover the Earth affects the amounts of sunlight our planet absorbs.

In this activity, learners are challenged to design and construct a windmill to harness the power of wind.

The goal of this activity is to design, build and test a house or toy for an animal.

In this activity, learners will discover what colors are in different markers, and may be surprised at the results.

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.

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 Energy and Environment activity (page 9 of the PDF), learners calculate the mass of a piece of gum, compare it to the mass of the gum's packaging, and then create a bar graph of the results.

In this activity on page 24, learners perform experiments to examine whether or not trash can float, blow around, or wash away.

In this activity, learners are challenged to design a planktonic organism that will neither float like a cork nor sink like a stone.

This activity provides a hands-on experience with a scale model, a relatively high viscosity fluid, and feeding behaviors.

In this activity, learners are challenged to design, build and test a birdhouse that will stay cool in the sun.

Learners design their own experiment to investigate how pollution diffuses through ground material.

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 (located on page 2), learners will construct tiny model geysers out of film canisters, warm water, and antacid seltzer tablets.

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

In this activity, learners take on the role of a carbon atom and record which reservoirs in the carbon cycle they visit.

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

Learners will build and experiment with their own windmills made from simple household materials.

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