Fair testing in Science
We are learning about seeds and how they disperse or spread. Sycamore seeds disperse by spinning to the ground and are like mini helicopters. We have been making different types of helicopter spinners. We could change the colour, the number or type of paper clips, change the paper, or the size like small or big. To be fair we only changed one thing from our control helicopter and we tested them by flying them in the school hall.
Here are some photos of us doing that!
