Since then we have engaged in learning experiences and play situations to gain a better understanding of structure. We've looked through books and viewed some clips. We've learned that shapes and positioning can make a structure stronger or weaker.
Since we have to break our bridges to relieve the big Lego blocks for others to enjoy, we decided to take a closer look at our designs. We wondered which bridge was the sturdiest.
Armed with weights to a total of 4.43kg we began the challenge. We decided we needed to use a chart to document the numbers.
One bridge left to stand the test :)
The children all understood the concept of strength by viewing the sheer quantity that they were able to pile onto their bridges.
Hi Elaine - looks like a fun activity that gets the students experimenting with different designs. I was wondering if the students had the opportunity to build several bridges in order to improve the design. After reading this post I was realised that maybe we could integrate this into PE and build some bigger bridges to carry people using some of our gym equipment and the climbing frames.
