In this outdoor, night activity, learners track nocturnal animals' footprints, droppings and other signs of their presence.

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

In this outdoor fall activity, learners find out what living in or under a layer of leaves is like.

In this activity, learners design and build a simple wind vane —one of the oldest kinds of weather tools— and use it to show wind direction.

In this activity, learners build handheld rockets and launchers out of PVC pipes and plastic bottles. Use this activity to demonstrate acceleration, air pressure, and Newton's Laws of Motion.

In this activity, learners will explore the ways natural materials can produce sounds. Appropriate for any age, learners can make individual music or create a symphony with others.

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 will observe how air interacts with a paper helicopter. Learners will test different variables of weight, size, and shape.

Learners place water and part of an antacid tablet in a film canister. The reaction creates a gas reaction that launches the film canister like a rocket.

In this activity, learners will investigate the part of soil. Explore how clay, silt, and sand make up the dirt in your background. Activity includes step-by-step instructions and extension ideas.

In this activity, learners model atmospheric convection currents using food coloring, water, and clear cups. Activity includes step-by-step instructions, STEM connections, and more.

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

In this activity, learners will investigate and compare the root systems of plants. Explore how weed and edible plant roots differ, and take a closer look inside with the careful use of a knife!

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

In this outdoor activity/field trip, learners investigate organisms that live along the ocean's rocky coast.

In this activity, learners walk the sides and interior angles of various polygons drawn on the playground. As they do so, learners practice rotating clockwise 180° and 360°.

A design challenge that takes paper airplanes into an entirely different direction: a magnus glider uses cups and and rubber bands to create a glider that uses the same forces that a curveball (from b

In this activity, learners explore the structure of plant leaves. Learners find out what happens when they coat either the top or bottom sides of leaves with petroleum jelly.

In this activity, learners discover how exercise helps keep the body healthy. Learners increase their heart rates by running and understand how running fast versus walking affects their pulse rates.

In this math activity, learners observe and sketch cracking patterns in pavement.
