In Year 5 we have been looking at forces and parachutes.  We had to plan an investigation to look at the effectiveness of parachutes.  Using the question;

What could we change to make parachutes different?

Different groups planned to change one variable only to keep the tests fair.  One group changed the size of their parachute, another group changed the material, another group change the thickness and another group used paper.  We timed how long each parachute took to fall to the ground and recorded the results. Then, we discussed them.
