Dear Bloggers,

1/2S and the rest of Year 2 investigated balance in their classes last week.  They built a see-saw which is a first order lever.  We identified the pivot, effort and load.  Initially the students used the large lego from Early simple Machines to create their see-saw and create balance with equal effort and laod weights an equal distance from the pivot.  Students were then challenged to create balance where the load was 3 times heavier than the effort without adding extra effort.

The Alexandra and Claudia were amongst the first to solve the problem.  They moved the heavy load in closer to the pivot (reduced the load arm) for partial success but also elongated the see saw on the other side and moved the effort even further out.  Balance was achieved.  Well done girls that was a very impressive solution to the challenge.  The students then used the smaller lego from the Simple Machine Kits to translate their design into a smaller format using many new pieces.
