We have been learning about air resistance and gravity in our science lessons. First, we designed and made a costume that we hoped would slow us down through air resistance. We timed our runs without our costume then timed our run with the air resistant outfit. We recorded our results and took timings from 3 runs so we could then find the average speed. Next, we plotted our results on a line graph and evaluated our findings, thinking about what went well and what we might change if doing the test again. 
We then made a paper helicopter. We wanted to see if changing just one variable would change the speed of the paper falling to the ground. We worked in small teams and discussed our findings. We had to make sure our test was fair and we took several timings to ensure our results were accurate.
