These STEM challenges involve very little set up. They're great for a day when you need a last minute plan! I use them as sub plans, but they're also great on days when your normal plan falls through. Eight different STEM challenge activities are included. Each activity should take between 20 and 40 minutes to complete.
The materials required for each of the activities are items found normally in the classroom (paper, glue, tape, books, etc.). Two graphic organizers for the engineering design process are included!
