In science and technology we are looking at the Bernoulli effect - the change of air pressure with the speed of air movement. All classes conducted investigations into the flight time and distance of helicopter seeds (maple seeds). In technology we will learn how to present these scientific results in an interesting manner. Over the next two weeks we will be conducting fair tests into paper helicopters and looking at NASA's helicopter "Integrity" which has completed 17 flights on Mars.
