The wheel & axle lessons are supported by three relevant and captivating activities designed to engage children with engineering experiences and teach them to actively think and question the world around them. During these lessons, participants will make a pinwheel, observe gears on a bike, and make recycled cars. Additionally, participants learn to identify wheel & axle as a simple machine, use higher level thinking to make comparisons, ask and answer questions, make predictions, and test hypotheses. Participants will be required to work together, encourage teamwork. and necessitate collaboration. We hope you enjoy this opportunity to show others that engineering and science are fascinating, useful, and fun! (PDF, 27 pages)
