About Our Team
Our team is from Shrewsbury, Massachusetts, United States. We are from Oak Middle School, and are in the 5-8 age category.
The four of us cooperated well to eliminate problems with our windmill. We are a group of 4- 2 boys and 2 girls. We discussed our ideas a lot before picking a final design.
Was a REcharge Labs MacGyver Windmills kit used for this project? Yes
What was the biggest challenge in trying to get your windmill to work properly? The string kept wrapping around the wrong places and keeping the windmill from working properly.
