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 ...

Catalyst: 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 ...

Friction: Friend or foe?

What part does the force of friction play in our everyday lives? Friction can be an advantage (friend) or a problem (foe). Join interviewer Doug Traction and professors Static, Slide, Rolling and Fluid at the National Tribology Research Centre as they have forceful fun investigating friction. This video won a prize in the ...

Experimentals: Do different things fall faster?

Want to find out what happens when you drop a watermelon and an apple from the top of a building? In this clip, Bernie Hobbs and Ruben Meerman, investigate whether the mass of an object influences how fast it falls. Bernie and Ruben ride the 'Giant Drop' at Dreamworld, drop a watermelon and apple from an eighth floor balcony, ...

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.

Pushing and pulling: assessment

Test your understanding of push and pull forces by moving animals using monkey power. Investigate and then predict the effects of applying a force to move a range of objects of various mass. For example, select two monkeys to move a pelican, and predict whether they will move the pelican slowly, quickly or too fast.

Pushing and pulling

Move animals from a boat to their new home in a zoo. Put them on a cart, then use monkeys to push or pull them up a hill. Use the minimum amount of force needed to move each animal. For example, use a single monkey to push a pelican or use three monkeys to pull a zebra. This learning object is a combination of three objects ...
