A group of children faces a big problem: how to move a pumpkin from the garden to the porch. They test a lever versus wheels and an axle, lifting and rolling the pumpkin to see which method requires less effort. Simple text and clear pictures show the kids making observations, measuring results, and deciding which simple machine does the job better. The story introduces basic engineering ideas and shows how choosing the right tool can make a tough task easier.
