Investigating Air Resistance


We raced across the yard and each time we increased our surface area in order to prove that the greater the surface area, the more air resistance acts as a force and slows the momentum of a moving object.

Save Eggbert!!!

Using their knowledge about air resistance and gravity, Y5 planned an investigation into creating the perfect parachute. They were presented with a variety of independent variables and chose the investigate; does the material the parachute is made of matter? They had to plan an investigation which would test the suitablity of 3 different materials for parachutes but keep all other variables (such as the height of the drop, the attached object etc) the same. Once they had determined their 'best' parachute, they then tested it on "Eggbert" - if he landed safely, their parachutes fulfilled their purpose, if Eggbert didn't survive the fall then their parachutes were deadly!!

Just for fun...what happens if we land on a harder surface??!

Investigating Friction


We planned an investigation into which surface creates the most friction. Firstly, we took rubbings of the soles of our shoes and analysed the patterns to determine who had 'safer' shoes and 'slippery' shoes based on the grips and depth of patterns created. Next, we decided to investigate which surface area would create the most friction against our chosen shoe. We chose 5 surfaces to focus on and planned the independent, dependent and control variables and set about conducting our experiement. Our results confrimed our predictions: the rougher the surface area, the greater the force of friction and the slower the object moves.
