📖 The Paper Airplane Trial
Noah folded two paper airplanes using the same size paper. One had wide wings and the other had narrow wings. He launched each plane from the same line and measured how far it traveled. The wide-wing plane flew farther in the first trial, but Noah knew one flight was not enough evidence. He repeated each launch five times and compared the averages.
1. What feature does Noah change between the airplanes?
2. What does he keep the same?
3. Why does he repeat each launch?
4. Why might averages be more useful than one trial?
