In Science, we have been exploring the impacts of friction and air resistance.
Here are the definitions:
We first tested which object would have the least amount of friction on a surface: an ice cube or wooden cube? Our prediction was that the ice would be the quickest therefore it has the least amount of friction. Our scientific enquiry type was ‘fair and comparative’ tests.
The children then went on to test air resistance (or drag). We tested that if our surface area increased would it slow us down or speed us up? Bin bags were our equipment of choice, have a look at our experiment:
We found out that an increased surface area means more air resistance therefore, we ran slower with the bin bag than without.
