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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.
