Oceans absorb the greatest amount of solar radiation on Earth. Ocean warming can lead to glaciers melting and ocean acidification.

Learn how sound travels in waves and how it is measured in this backgrounder.

Find out what happens if you spin the colours of the rainbow in this hands-on activity.

Do you weigh the same on Jupiter as you do on Earth? Learn to calculate your weight on a different planet.

Take a tour of different rooms in your home. Which items in each room use electricity? How do you know they use electricity?

Rainbows are beautiful examples of optics in nature. We see them thanks to the reflection and refraction of visible light and water.

Balls go up and down. But what makes for a good ball? Find out by exploring which materials bounce.

Learn about the different types of radiation, how they interact with atoms and how they can affect you.

These two “point-counterpoint” videos provide arguments for and against using nuclear energy to generate electricity.

Create a model of ocean currents and learn how currents are formed.

Have fun discovering what magnets can pick up in this hands on activity.

Could we use radio waves to charge electrical technologies in the future?

Things are heating up! Explore the temperature change that occurs in an exothermic reaction and the role of catalysts is this chemistry activity.

Can your body be a source of electricity generation? Maybe, if you understand heat transfer. Explore this concept through a 2013 invention by a Canadian teen.

Electricity demand changes constantly. Suppliers need to generate more electrical energy when demand is high, and less when demand is low.
