Kindergarten kit Anna and Leon experiment with lever, pulley and magnet


Lever, pulley and magnet – there is something moving !
This kit revolves around the forces which children come across in their daily lives. They will be surprised to discover where a lever is hidden and where a pulley turns round forces. Especially attractive for children are the effects of magnetic force.
With the materials they can detect the forces of lever, pulley and magnet.
Exciting, curricula-based experiments will enable the children to explore phenomena in environment and technics. Their interest in natural sciences will be wakened and encouraged.
The experiments are fail-safe and easy to reproduce. The robust materials are compactly stowed in a plastic tray with lid.

experiments
  • 1 - Everything has its weight

    experiment "Everything has its weight"

    The children should be introduced to the following knowledge with the help of the experiment:
    - The weight of a body depends on its size and the material it is made of.
    - All bodies heavier than air fall down when released from a height.
    - All bodies fall to earth at the same rate, regardless of their weight. Because of different shapes and surfaces, they are slowed down by air resistance.
    - The force with which a body hits the ground depends on its weight.


  • 2 - At equilibrium

    experiment "At equilibrium"

    The children should be introduced to the following knowledge with the help of the experiment:
    - If an object or body remains still or lying in its position, it is in equilibrium.
    - Balance depends on the center of gravity of a body.
    - By balancing, you can bring a body back into equilibrium.


  • 3 - What is heavier ?

    experiment "What is heavier ?"

    The children should be introduced to the following knowledge with the help of the experiment:
    - All bodies have a weight or exert a weight force.
    - The mass of the body is decisive for the weight force.
    - Bodies that have the same size and shape can exert a different weight force due to their mass. Thus, a small body can also be heavier than a larger one of different material.


  • 4 - A lever can help

    experiment "A lever can help"

    The children should be introduced to the following knowledge with the help of the experiment:
    - Many practical devices and tools in our everyday lives are based on leverage.
    - Levers are simple machines that can be used to lift large weights with a small force.
    - The effect of a lever depends on the position of the pivot point.


  • 5 - Up and down on the seesaw

    experiment "Up and down on the seesaw"

    The children should be introduced to the following knowledge with the help of the experiment:
    - Many practical devices and tools in everyday life are based on leverage.
    - The effect of the force applied depends on the length of the lever arm and the load to be lifted.
    - It depends on the weight and its distance from the pivot point whether the lever is in equilibrium.


  • 6 - Make it easier with a pulley

    experiment "Make it easier with a pulley"

    The children should be introduced to the following knowledge with the help of the experiment:
    - Simple machines can be used, for example, to direct the effect of a force in a different direction.
    - Loads can be moved upwards more easily with the help of a pulley.
    - However, no force can be saved in the process; the pulling force must be just as great as the weight of the load.
    - With a pulley block, force can be saved because the principle of force times distance is used here.


  • 7 - Everything is spinning around !

    experiment "Everything is spinning around !"

    The children should be introduced to the following knowledge with the help of the experiment:
    - A rotary motion can be transferred to another location with the aid of a chain or belt.
    - It is possible to convert a smaller number of revolutions into a larger one.
    - The amount of force required is correspondingly greater or less.


  • 8 - I want to stay this way !

    experiment "I want to stay this way !"

    The children should be introduced to the following knowledge with the help of the experiment:
    - In these experiments, the children learn about the phenomenon of inertia of bodies.
    - Solid bodies are at rest in the place where they are.
    - If a body is to move, force must be applied to bring it out of its resting position.
    - Bodies are inert, meaning they want to maintain the state they are in. They either want to remain stationary or continue moving when they are in motion.


  • 9 - It’s your turn !

    experiment "It’s your turn !"

    The children should be introduced to the following knowledge with the help of the experiment:
    - Energy can be transferred by an impulse.
    - Bodies can be in a state of rest or in a state of motion.
    - If a body that is in motion meets a body that is at rest, the latter can also be set in motion.
    - When meeting, a large part of the energy with which the body is moving is passed on to the body at rest.


  • 10 - Who is pulling me?

    experiment "Who is pulling me?"

    The children should be introduced to the following knowledge with the help of the experiment:
    - Forces act on bodies that are set in a rotating motion.
    - One of these forces is the so-called centrifugal force, which, for example, drives the gondolas of a chain carousel outward.


  • 11 - Magnetic force

    experiment "Magnetic force"

    The children should be introduced to the following findings with the help of the experiment:
    - Magnets exert an attractive force on certain materials.
    - There are objects that are attracted and objects that are not.
    - The attractive force of a magnet also acts through objects, but only to a limited extent.


  • 12 - Quite strong such a magnet !

    experiment "Quite strong such a magnet !"

    The children should be introduced to the following findings with the help of the experiment:
    - The attractive force of a magnet also acts through objects, but only to a limited extent.
    - The magnet does not have to touch the objects to exert its force on them.
    - Metals that react to the magnetic force can themselves be made magnetic for a short time, this is called magnetization.


  • 13 - Come here, go away !

    experiment "Come here, go away !"

    The children should be introduced to the following findings with the help of the experiment:
    - Magnets have different poles, a north pole and a south pole.
    - Equal poles repel each other.


  • 14 - Who is pulling the brake?

    experiment "Who is pulling the brake?"

    The children should be introduced to the following knowledge with the help of the experiment:
    - If two surfaces rub against each other, a braking effect is created by friction.
    - How strong the friction and thus the braking effect is depends on the type of surface and the strength of the pressure on the surface.
    - The braking effect can be increased or decreased by the nature of the surface.


  • 15 - Quite elastic !

    experiment "Quite elastic !"

    The children should be introduced to the following knowledge with the help of the experiment:
    - Elastic materials and bodies can change their shape.
    - A force is required to change the shape.
    - When the force is no longer applied, the original shape is resumed; this is referred to as elasticity.
