To end our social studies discussion on natural resources, we had a KidWind STEM challenge day. Students tried to create the blades of a wind turbine that would produce the most volts of energy. I had the base and volt meter set up in which partners would test their blades using. Each partnership was then given a hub in which they attached their blades.
Many decisions went into developing the best blades:
Materials used
Size
Shape
Pitch - which many learned about as the day went along
It was a wonderful day of students making a plan, analyzing and testing it, making changes, and retesting. While some students created wind turbines that moved, others did not and had to consider what they could do differently to make their wind turbines spin. It was so awesome to see all the thinking and processing going on. Powerful thinking and learning!
I kept all the information from the students and we will have another KidWind day in the future in which they will change something (variable) to test if their new wind turbines work better or worse then their original set.
Here are just a few pictures from the day:
