Racing game with one die

This is an interactive game that investigates probability by simulating a two-car race, in which the movements of the cars are based on the roll of a die. Cars advance when certain numbers are rolled, and the student can experiment with probability by selecting which car moves forward for a given outcome of the roll of ...

Probability and the gambler's fallacy

Mathematician Lily Serna visits Luna Park to explain a great probability pitfall. She shares a century-old tale from Monte Carlo casino, and then she puts its lesson to the test. If you flip a coin and it lands on heads three times in a row, what result would you predict for the next flip? Find out why intuition might land ...

Can you guess the weight of Uluru?

What is the "wisdom of a crowd"? Mathematician Lily Serna investigates a mathematical phenomenon that suggests that if you have a large enough crowd, with a broad variety of people making estimates, then the mean (average) answer of the crowd will be accurate! Find out if a crowd can guess the weight of Uluru from the ground ...

Chance and playing with dice

Have you ever played a game that required you to roll a dice? Did you know that you have equal chances of rolling any of the six numbers? Can you think of another experiment where you have an equal chance of getting one result or the other?

Seeing red: what is the red-eye effect?

Have you ever wondered what causes that annoying 'red-eye' in photos taken with a flash? How can you avoid or lessen it? Marko Moutafis uses eye models as he takes us through a lively demonstration to help answer these questions. He entered this video into the 2013 Sleek Geeks Eureka Science School Prize competition.

Red cabbage pH experiment

It might sound 'un-sciencey', and have a bad smell, but red cabbage is actually very useful for testing the pH of liquids. Added to well-known liquids like lemonade or vinegar, red cabbage juice changes to 'pretty colours'. In this clip, Surfing Scientist Ruben Meerman explains the colour changes and how red cabbage juice ...

Properties and behaviour of gases

All substances are made up of tiny particles. A change in temperature can change the way these particles behave. Watch as the Surfing Scientist demonstrates how a gas behaves when it is heated. Find out whether the balloon gets sucked or pushed into the bottle!

Experimental probability

This is an interactive resource that enables students to conduct virtual probability experiments using a spinner or a pair of dice. The student can manipulate the relative sizes of the different coloured segments of the spinner or the numbers on the faces of the dice to investigate the effect of these changes on probability. ...

Spinner

This is an interactive resource that investigates experimental and theoretical probability based on a spinner. The student can select the number of segments on the spinner and simulate spinning the spinner with a mouse click. The outcome of each trial is recorded in a table along with a comparison between the cumulative ...
