STEM Challenges: This amazing challenge uses one basic material- Straws! Add a few more items and see if your students can build a suspended bucket that will hold weight!
Team Building Task-The Cup Challenge - take a rubber band and tie 6 strings to it (though I think 5 would work if you want smaller groups). Participants must use only the strings to move 6 cups into a pyramid formation. You can make this a competition between the groups or give them harder cup moving tasks.
