Today we made helicopters from card. We made a large and a small helicopter. We cut out the helicopters from card. We then folded along the dotted lines. We put a paper clip on the bottom of the helicopters. Then we tested them to see which helicopter landed faster. We tried putting two paper clips onto a helicopter to see what would happen. We held races between different helicopters. We discovered that when we put two paper clips onto the big helicopter that it just fell to the ground and didn’t spin. When we put two paper clips onto the smaller helicopter it spinned more and fell to the ground faster. We also tested dropping the helicopters from different heights. We discovered that if you put the big helicopter a bit lower than the small one, they both reached the ground at the same time. We discovered that by standing on a chair, the helicopter worked better by coming down faster and spinning more. We enjoyed doing this experiment.

Near the start of the year we were doing science work on how food goes off. Sam brought in a Galia melon that was starting to go off. At that stage it looked like a normal melon with a bit of mould on the bottom. We left it on the window sill since then and we have been keeping an eye on it ever since. Now it doesn’t look like a normal melon at all. It has become very mouldy and mushy. It has also shrunk and got wrinkly. There is only a little smell from it. This is Science Week and we thought you’d like to see a photo of it.. This is what the melon looks like now:
