In this activity (page 12), learners explore how molecules self-assemble and how molecules must fit together, like a lock and key, in order to identify each other and initiate a new function as a comb

Look at pictures through different color filters and you'll see them in a new way. People have used color filters in beautiful photography or sending secret messages.

This fun and simple hands-on astronomy activity illustrates the value of supernovae in the universe.

In this goopy activity (page 2 of PDF under GPS: Glaciers Activity), learners will model glacial movement with “gak,” a white glue and liquid starch mixture.

In this outdoor, night-time activity, learners discover how to spot eye-shine (reflection of light from an animal's eyes) by using a flashlight to play a simulation game.

When you teeth clatter, they make quite the racket disproportionately to how much they actually sound to someone else.

Have you ever heard of a camera without a lens? In this activity, learners create a pinhole camera out of simple materials. They'll see the world in a whole new way: upside down and backwards!

In this activity, learners use an origami template to design eight amino acids. Learners configure the amino acids to form a protein. Use this activity to introduce proteins and amino acids.

Make snack time into measuring time and learn to read Nutrition Facts labels. Try this when you’re using “pourable” foods, such as cereal, yoghurt, or juice.

This science activity demonstrates the dominant eye phenomena. What does your brain do when it sees two images that conflict?

In this activity, learners examine the culture and history of the tomb site.

In this activity, learners explore how engineers design devices that can detect the presence of pollutants in the air.

Learners match puzzle pieces to outlines of a DNA strand. The puzzle pieces represent the four chemicals making up DNA base pairs: adenine, thymine, guanine, and cytosine.

In this activity, learners explore the concept of valve operation and how engineers have adapted valves for use in mechanical heart valve design.

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 explore surgical instrument design. Teams of learners construct surgical instruments from everyday materials.

In this interactive game, learners listen to the songs of four different thrushes and then try to match each bird with its song.

In this engineering design challenge, learners make a bird and then control its flight with attached strings.

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 explore sound by constructing tube zithers, stringed instruments from Southeast Asia and the South Pacific.
