It was one of my son's favourite Christmas gifts and has helped him advance in his science and technology learning. It comes with all the parts you need to build seven different working machines.
Included is a guide to building a fan, an egg beater, a chainsaw, an exercise bike, a car window, a blender, and a record player. In addition to this, children can use their imaginative skills to come up with their own building projects and make their own inventions.
It helps kids get familiar with the different kinds of gears and how they work. This playful way of learning helps children gain much more insight than they would get from mere book learning or classroom learning, as they are self motivated to investigate, gain skills, and understand scientific and technological concepts.
As a homeschool teacher, I am using this set to teach my children about simple machines, movement, force, and speed in a hands-on way.
