In this activity, learners construct a home-made journal with simple, everyday materials.

In this small-group activity, learners assume the roles of pilots, air traffic controllers, and NASA scientists to solve five Air Traffic Control (ATC) problems.

An ordinary camera has a lens that makes an image on film. In a pinhole camera, a small hole replaces the lens.

In this activity, learners use simple, everyday materials to experiment with balls and ramps.

In this activity, learners use found natural materials to create a water haven for bees and other insects.

In this outdoor activity, learners play a game of Tag to discover how neurons attach themselves to each other to form a chain.

In this three-part activity, learners use food to determine the effects of wind, sandblasting and water on regolith (dust) formation and deposition on Earth.

This is an outdoor activity designed to demonstrate evolution of feeding behavior in flocking, schooling or herding animals that maximizes allocation of food resources and enhances survival.

Lakes, streams and other freshwater bodies are a habitat for lots of living things, big and small.

In this activity, learners use the design thinking process to design and build their own aqueduct, or water bridge.

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 will measure the length of a shadow and use the distance from the equator to calculate the circumference of the earth.

In this activity, learners use a simple 3D model to discover why the Moon has phases.

In this activity, learners will test soil content using their sample, some water and a container that seals.

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

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 model a population of deer and see how the number of deer changes over time.

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 indoor or outdoor demonstration, use a large and small ball to illustrate conservation of energy and momentum.

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