Incoming.....Parachute testing. 

As part of year 5's science topic of forces we have been studying air resistance. 

We worked in groups to create 4 parachutes of different sizes. 

Parachute A was 15cm by 15cm 

Parachute B was 30cm by 30cm 

Parachute C was 45cm by 45cm

Parachute D was 60cm by 60cm 

Then we dropped them from a height to test how long it takes to fall to the ground.  Can you see which one was the quickest? Can you tell which one was the slowest?
