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

Learners add two dyes to mineral oil and water, and then compare their miscibility (how well they mix) in each.

What's a more compelling problem to solve than being stranded on a deserted island?

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

In this demonstration, learners explore a variation of a Foucault pendulum, but upside down.

In this chemistry demonstration, acid rain is simulated in a petri dish.

In this activity, learners discover the principles of edible glass by making a supersaturated sugar solution.

In this simulation of natural selection, learners use binder clips in three different sizes to represent the diversity of beak sizes in a bird population.

In this two-part activity, learners map a navigation plan to get from Earth to Mars and back. In activity one, learners represent the orbital paths of Earth through dance and dramatic movement.

This is a series of demonstrations about different electrical and magnetic phenomena.

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

Molecular gastronomy is the scientific study of food preparation. Learners use self-assembly techniques to create edible capsules of chocolate syrup (food grade ingredients are required).

In this activity (on pages 49-54 of PDF), learners play with tangrams, a set of triangles, squares and a parallelogram that can combine into a larger square as well as all sorts of other shapes.

In this optics activity, learners examine how polarized light can reveal stress patterns in clear plastic.

This laboratory activity helps learners understand the concept of biological succession by simulating the process in a microenvironment with various protozoans.

Learners add acid rain (nitric acid) to two cups that represent lakes. One cup contains limestone gravel and the other contains granite gravel.

In this optics activity, learners explore diffraction by adding wax blocks to a ripple tank. The wedge-shaped blocks act as obstacles that the wave must bend around.

In this activity, learners will create a diagram of the ocean zones and determine what organisms live in each zone.

In this activity, learners explore how a hydraulic pump works. Learners work in teams to design and build a unique water fountain that employs a hydraulic pump.

In this activity, learners explore sports engineering and advanced materials development.
