Wind Power Wonders: Exploring Force with Windmills

Grade 3Science4 days

The 'Wind Power Wonders' project engages third-grade students in exploring the science of wind energy through the design and construction of windmills. Focusing on the concepts of balanced and unbalanced forces, the students learn how these affect object motion specifically in relation to windmill performance. The students participate in hands-on laboratory activities and design challenges, culminating in the creation of a functional windmill model that demonstrates energy harnessing efficiency. The project emphasizes critical thinking, collaboration, and practical application of scientific principles as students test, refine, and optimize their windmill designs.
