The children in Class 4 devised an experiment to test the effects of air resistance. Through discussion and peer challenge they eventually agreed to drop three teddies out of the staffroom window. They devised a fair test by keeping all except one variable the same: same sized teddies and same distance of fall.  The only difference was the size of the parachute.  Children timed the drop and then discussed the results.  The smallest parachute, with the least air resistance fell the quickest whereas the largest parachute took longer to deliver ted safely to the ground.  Our next job is to show our results in a graph.
