Scientific set 4M The machine from boxes allows to turn empty boxes into a mobile design. The car from boxes can go, thanks to the engine and force of friction. The set is designed for children from 5 years of preschool age.
Assemble the work according to the instructions with pictures. It also has an explanation of the principle of operation, interesting facts. Turn on the racing wonder car and watch your hands come to life!
Green Science kits involve children in research, teach them to assemble devices according to instructions. In the process of compilation develop curiosity, thinking, attentiveness, imagination, design skills, ingenuity. Such classes form a focus on results, introduce physics, mechanics, robotics in a game format. Creating a car out of boxes distracts from the Internet and motivates to be interested in science. The set is suitable for classes at home, on development courses according to the STEAM educational method.
Why does the car move? When you turn it on, you close the circuit that connects the battery to the motor inside the gearbox housing. Electric energy flows from the battery to the engine, which converts this energy into mechanical rotation. The axis of the engine rotates at high speed, but low power, and by itself will not be able to move the car. The engine rotates several gears inside the gearbox housing, which reduce speed and increase the mechanical power of the engine, making it more efficient. Most cars, especially real cars, use the gearbox to change power and speed in a similar way.
The traction axle of the car rotates two large wheels that move the car forward as it rotates. The wheels must engage with the surface on which the car is moving if the car is moving forward. The wheels depend on the force of friction with the surface. Friction & ndash; it is a force that arises between any two objects that touch each other. Real cars increase friction with the road by using rubber tires that improve traction.
Friction & ndash; a very important force that greatly affects our lives. Sometimes we need to reduce friction, so we lubricate machine parts. Skaters have a thin metal blade on their shoes to slide on smooth ice. In other cases, we want to increase friction, so racing cars have wide wheels, and the soles of sneakers are made of rubber and have treads for extra traction.
The kit has all the necessary parts to assemble the car. The case consists of the back of the package. Additionally required: 1 AAA battery and Phillips screwdriver.
