Many common household cleaners are antimicrobials.

In this activity, learners explore the design of tall structures such as skyscrapers and telecommunication towers.

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.

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

This display shows the dangers of acid rain on buildings and other structures as two concrete bunny rabbits are disintegrated by sulfuric acid. Learners scrape chalk onto the concrete bunnies.

In this activity, learners explore how engineers work in a team to solve problems.

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 create a working model of a nail clipper. This activity helps learners learn the basic principles of simple machines, engineering design and model building.

This activity models the way Landsat satellites use a thermal infrared sensor to measure land surface temperatures.

In this chemistry activity, learners will learn how to make their own pH indicator using cabbage leaves, and then test common household items with their homemade indicator.

In this activity, learners review the history of gumball machines and explore potential and kinetic energy, while working in teams to build a gumball slide.

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.

In this activity about depth perception, learners create an optical illusion in a shoe box.

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

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.

In this activity, learners construct an indoors obstacle course and discover how using an eye patch can help them complete the course in the dark.
