In this outdoor activity, learners use pegs (like tent pegs) and string or elastic to simulate drill sites and roads in Northern Canada.

In this activity, learners construct cars that are powered by hand-made, electric propellers.

Learners mix liquid water with solid cornstarch. They investigate the slime produced, which has properties of both a solid and a liquid.

This is part 1 of the three-part "Crayon Rock Cycle" activity. In this activity, learners explore how sedimentary rocks form.

In this activity, learners create air cannons out of everyday materials. Learners use their air cannons to investigate air as a force and air pressure.

In this outdoor activity/field trip, learners conduct experiments to explore where dragonflies and damselflies perch or rest, and how the flies change behavior in reaction to other flies or fly decoys

In this activity about global climate change, learners will conduct an experiment and collect data to compare the amount of carbon dioxide (CO2) in four different sources of gases.

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

In this activity, learners make a photographic image—without a camera!

In this activity, learners construct a rocket powered by the pressure generated from an effervescing antacid tablet reacting with water, and build a launch pad for their rocket.

In this physics activity, learners construct a small-scale version of a classic carnival game.

In this activity, learners explore the engineering design process and the basic mechanics behind building bridges as they build one themselves using gumdrops and toothpicks.

In this activity, learners explore surgical instrument design. Teams of learners construct surgical instruments from everyday materials.

In this outdoor mapping activity, learners explore where plants grow and map plant-distribution patterns.

Cardboard Automata are a playful way to explore simple machine elements while creating a mechanical sculpture.

In this outdoor activity/game, learners use thermometers to simulate how lizards survive in habitats with extreme temperatures.

DNA is the thread of life. Encoded in its genetic sequence is the information that makes each of us unique.

In this activity, learners use pegboard and straws to build a three-dimensional model of the periodic table.

In this activity, learners explore acids and bases by preparing six solutions that combine vinegar and ammonia, ranging from acid (all vinegar) to base (all ammonia).

In this activity best suited as a demonstration, learners observe that when a piece of iron gets too hot, it loses its ability to be magnetized.
