We had a blast in Science today, as we were testing the strength of different materials as part of our Structures and Materials unit. I did a whole class demonstration first, where we were testing how much weight one or more straws could hold before they would break (we tested the strength by hanging a small container from the straws, and then increasing the amount of weight we placed into the container). The students quickly realized that by bundling straws together, they can support a lot more weight than by using only one or two straws.
Next, the students worked in groups to see what kind of paper was stronger (by shaping the paper into cylinders and placing books on top): looseleaf, printer paper, or cardstock. There was a lot of hooting and hollering as the kids were blown away by just how much weight the cardstock could hold up - check out the picture below!
