Project Overview
In this STEM Design Challenge, students are tasked with designing and constructing their own blades using any available or provided materials. To evaluate their creations, all students will use a fan or wind tunnel as a consistent power source, with everyone standing the same distance from it and using the fan set to the same setting. Throughout the challenge, students will conduct multiple trials to test their blades’ performance and will have the chance to redesign their blades based on their findings.
Student Award
1. Engineering Award- For the best Re-design 2. Master Architect- For the best blade design 3. Innovation Award- For the most innovative design.

Project Overview
Our fan was constructed from wood sticks, cardboard, glue and gems and only has 3 blades. During our three trials we changed things like pitch and weight on our fan but our fan speed got worse as we went on. We used a few gems on the fan blades to make it look good.
