S.T.E.M. Bridges

For the last 2 weeks our task was to design a bridge that would hold 340g of weight for 20 seconds. The materials allowed were - 30 straws per group and a teacher’s (Mrs Jack’s) handful of playdough. Scissors, a metre of string, 4 paper clips and masking tape.

We had to remember what a bridge was and work together collaboratively to complete the task. First we designed 3 different types of bridges. We picked one to create and test.

We were very successful. Nearly all of the designs worked and held the weight for the amount of time.
