The perfect paper plane

Let us suppose you have developed some designs for paper planes and wish to 1___________ which of these is best. Having 2___________ paper planes in the past will allow you to 3___________ a hypothesis – for example, that planes with wider wingspans fly further. You will then need to 4___________ hypothesis by designing an experiment. This is relatively straightforward. You simply make some planes with 5___________ wingspans, throw them, measure how far they travel and record the distances. The planes should be thrown at least five times. You should record your results, 6___________ them on a graph and then examine your 7___________ before writing them up. In your conclusion, you should say whether your 8___________ hypothesis has been confirmed or not. If it has not, it will need to be modified.
