Secondary science: models and simulations

These seven learning activities, which focus on 'models and simulations' using a variety of tools (software) and devices (hardware), illustrate the ways in which content, pedagogy and technology can be successfully and effectively integrated in order to promote learning. In the activities, teachers assist students to interpret, ...

Spacewalk game

This is an interactive resource that explores the International Space Station through a Station Spacewalk Game in which participants conduct virtual NASA repair work on the International Space Station. In the game, participants leave the airlock and complete tasks executed by astronauts to help power up the space station ...

Was Galileo right?

This is an interactive resource about the effect of gravity on objects of various mass during free fall. Students investigate the effect of gravity on two objects and predict what the position-time and velocity-time graphs will look like. They then compare graphs for the light and heavy objects and explain the differences, ...

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.

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 ...

Energy skate park

This is an interactive resource about the potential and kinetic energy changes as a skater rolls around a skate park. Students learn about conservation of energy with a skater, they can build tracks, ramps and jumps for the skater and view the kinetic energy, potential energy and friction as he moves. Students can also ...

Do heavier things fall faster?

Will a medicine ball or a basketball hit the ground first when dropped at the same time from the same height? In this clip, Catalyst's Dr Derek Muller investigates what influences the speed at which objects fall. Derek challenges some people in a market to make a prediction and explain their thinking, before he finally ...

Meet the BFFs: four fundamental forces

We all know something about gravity, but what about the other fundamental forces of physics? Explore the properties of two familiar forces experienced in daily life, and of two less familiar ones. How do they interact, and what keeps everything from falling apart? This video was Kate Dent's entry into the 2013 Sleek Geeks ...

Ramping it up, Egyptian pyramid style

How did the ancient Egyptians move and lift huge stones during construction of the pyramids? Secondary student Angus Atkinson designed an experiment to find out how the lives of pyramid workers could have been made easier. See how as you watch this video, which he entered in the 2013 Sleek Geeks Eureka Science Schools Prize.

Meteorites, asteroids, orbiting and gravity

Learn how Galileo Galilei's work overturned Aristotle's ideas about falling objects and led to an understanding that Earth revolves around the sun. Find out how Isaac Newton showed that the laws of motion on Earth and in space are the same, and that he discovered that the gravitational force of attraction between any two ...
