Wheels Help Us Move
A wheel is round, and it rolls. Wheels help us move things.
Try to push a big box across the floor. It is hard, because the box rubs the floor. Now put the box on a cart that has wheels. The box moves with ease!
A wheel turns around a rod called an axle. The axle holds the wheel in place.
Many things have wheels. Bikes, cars, wagons, and skateboards all have wheels. Wheels help us go far and carry heavy things.
