Lever Investigation - Table top seesaws
In Science, we have been looking at how levers work; exploring how the position of fulcrum, load and effort impacts on use
We needed to identify where the best position was for the fulcrum in a simple lever. Identifying those things that needed to stay constant while we took measurements and made observations for our main variable. We had to plan methodically to ensure testing was fair, logical so that the results were not unreliable.
