Anatomy of a raindrop

The water cycle is the circulation of water on, in and above Earth and it involves a number of stages and changes of state. This clip describes the water cycle and also how modern technology has contributed to our understanding of the shape of raindrops and its relationship to precipitation. Discover how raindrop shape ...

Projectile motion

This is an interactive resource about projectile motion. Students use a simulation of a cannon to fire various objects. They can set the firing angle, initial speed, height and mass, with or without air resistance. Students are encouraged to make a game out of this simulation by trying to hit a target. This interactive ...

Friction

In this learning sequence, students explore frictional forces. They investigate how friction changes with different contact surfaces in wet, dry and icy conditions, and the effect this has on braking. Finally they apply this learning to the real-world situation of tram travel, and explore why sand is used on tram tracks ...

Measuring gravity

Did you know you can measure gravity? The more mass an object has, the more gravity it has, so by measuring the mass of something, you can figure out its gravity. Why do you think climate scientists may want these measurements? Watch this NASA animation to find out.
