Mrs. Sanborn’s fourth grade students are competing with their fellow classmates in the crayon tower challenge. They are working as teams in this STEM activity to figure out how to build the tallest tower using only one crayon box and a ruler. The tower has to be able to stand up by itself with no one helping hold it up. It took several tries and some brainstorming, but they were able to get their towers to stand up. They were excited to see how tall they could get them and see how long it would stand.
