We have completed two fun science experiments this week. On Monday we tested two different bridge designs to see which was stronger. We tested a arch and a square structure. After the students constructed their bridge they tested the strength with weights.
On Wednesday we tested three different beam styles for strength. First students had to construct, out of paper, an accordion beam, a rectangular beam and a box girder beam. After construction was complete the students completed a fair test to see which beam was strongest.
Here's a picture collage of both of the experiments.
