Hauling a Pumpkin: Wheels and Axles vs. Lever

Noah and his mother are at a pumpkin patch. Of course, Noah wants a BIG pumpkin. How will they be able to get the pumpkin to the parking lot? “The pumpkin is heavy! What can help him carry it?” (5) Mom sees a shovel, which she uses as a lever with a fulcrum. She lifts the pumpkin, but it doesn’t get the pumpkin any closer to the parking lot. Noah sees a wagon with wheels and axles. Once this simple machine is analyzed, mom gets the pumpkin into the wagon. Noah is off to the parking lot. Noah’s smile could not possibly get any bigger!
