Why do we use cranes? How do cranes lift heavy things? Are there different types of cranes? Why don't cranes tip over? With this kit, children can experiment to find the answers to questions like these from their everyday observations. They will learn all about cranes by investigating levers and pulleys, and by building models of a wheel-barrow, a fixed pulley system, a block and tackle mechanism, and a tower crane.

Little Labs have step-by-step illustrated instructions so children can learn independently through easy, hands-on experiments. The pictorial guidebook has just enough text to reinforce vocabulary and aid in language learning, and also to advise parents and adult supervisors.
