Design a vessel that tests the limits of wind power given a set of off the shelf and recycled materials.

In this activity, learners of all ages can become food scientists by experimenting with flour and water to make basic pasta.

Learners experiment with a 2-liter plastic bottle containing water and four “divers." The divers consist of open, transparent containers with the opening points downward.

In this activity, learners separate a mixture of pebbles, salt crystals, and wood pieces. They add water and pour the mixture through a strainer.

In this activity, learners interact with a 3-D model of a watershed to better understand the interconnectedness of terrestrial and aquatic environments.

In this activity (on page 14 of PDF), learners use a pan full of flour and some rocks to create a moonscape.

In this activity, learners cut out and assemble wheels to explore how variations in fish body structures (mouth shape/position/teeth, body shape, tail shape, and coloration patterns) allow fish to sur

In this activity, learners explore how nanotechnology is being used to create new types of protective fabrics.

In this activity (on page 5 of PDF), learners use dry ice and household materials to make scientifically accurate models of comets.
