This morning Yr.6 looked at air resistance in parachutes. They decided which variable to test and then tried out three variations. Some groups tested the material the parachute was made from, some the size of the parachute and others the number of layers. They then selected their most effective parachute and dropped this from the upstairs window. Some were so effective that they went up and onto the roof!
Yr.6 also tried holding a full bottle of water upside down with just a table tennis ball as a stopper. They found that the large surface area of the tennis ball meant that upthrust from the air could hold the water in the bottle!
