This week we went to the science lab to learn about gravity and air resistance.

We planned our science investigation by deciding to investigate if the length of a spinner (helicopter blade) affects the speed its falls. Pupils planned the investigation by choosing a variable  to study (length), writing a hypothesis and stating the method as well as how they will keep it a fair test.

The class then went out to the hub, which they decided was the best place to drop the spinners. Once all the spinners were dropped and timed, the results and averages were calculation. Finally, pupils were able to conclude and evaluate their investigation.

“the spinner with the shortest blade fell quicker because  there is less surface area for the air resistance to slow the fall of the object” Hadi

“we kept the test fair by only changing one thing, the length of the blade. Next time we could test a different variable like weight by adding paper clips to the spinner” Jake
