Over the last few decades, physicists have come to realize that about 90% of the mass of every galaxy in the universe is made of an unseen substance called dark matter. Suitable for grades 11, and 12.

Quantum physics is considered by many to be the single most important advance in our understanding of the universe. This video introduces you to quantum physics via the double-slit experiment and the concept of wave-particle duality. Suitable for grades 11, and 12

Where does technology come from? Find out how the four key scientific concepts of electromagnetism, relativity, and quantum mechanics have empowered us to engineer technology. Suitable for grades 9 through 12.

The Global Positioning System (GPS) is a navigational tool that can pinpoint your location to within a few metres. Surprisingly, it incorporates a number of effects from Einstein’s theory of relativity. Suitable for grades 9 through 12.

Planck’s constant (h = 6.63 x 10-34 Js) lies at the heart of quantum physics. This booklet describes a laboratory activity in which students measure Planck’s constant using a simple electronic circuit. Suitable for grades 11, and 12.

Join Alice and Bob as they ask simple questions about our world that lead to three of the most profound revolutions in science: general relativity, quantum mechanics, and special relativity. Suitable for grades 9 through 12.
