Bundled Puff mobile project worksheet and PowerPoint - a fun activity for students of all ages. I allowed students to use any materials they had/brought in, but set a 50g weight limit. Students may blow as much as they want, but cannot cross the starting line. Fits well with physics and engineering design.
Sketch design, measure distance and time, calculate speed, modify and draw new sketch, measure again, answer analysis/reflection questions.
This bundle contains both the project worksheet and accompanying PowerPoint.
