Physical processes in everyday life

What, why, why? Children prefer to understand all physical processes in everyday life. Small experiments are not only fun, they also simplify understanding and ensure that what you have learned is remembered longer. Here's how to conduct centrifugal force experiments with your child.

Physics experiments are great fun for children.

What you need:

  • bucket
  • water
  • Straw
  • cord
  • Weights

A physics experiment for children - the water bucket

  1. Fill the bucket with a little water. Spin quickly in circles. The water is pressed against the wall.
  2. Now the children can also turn in circles with the bucket. The children can watch how the water behaves depending on how fast they turn.
  3. You can show the children the physical behavior of the water with a picture of a chain carousel in everyday life. If you sit in the chain carousel, you will be pushed almost horizontally when the carousel turns quickly.
  4. To make it clear how strong the centrifugal force presses the water to the bottom of the bucket, you can now turn the bucket quickly over your head. When it is warm enough and the children have a change of clothes if necessary, you can also let the children try to see if they can do it. You can repeat both experimental processes as often as you like - or have them repeated - until it gets boring.

Processes based on centrifugal force - a mystery

  1. Pull a cord through a straw.
    2. Small experiments in kindergarten - this is how you arouse children's interest in science

    To teach children about processes in the natural sciences of biology, chemistry and physics ...

  2. Tie two weights of about the same weight to both ends of the cord. The weights shouldn't be too heavy. For example, 20-50 g is perfectly adequate.
  3. Now give a child this construction with the task of making up the greater part The string must be above the straw without the child taking the string or the weight touched.
  4. The child can now only touch the straw. By rotating the upper weight, the cord is pulled upwards.
  5. This is also based on physical processes. The centrifugal force ensures that the upper weight is pushed outwards. As a result, the upper weight pulls the cord against the force of gravity and thus also the other weight upwards. An example from everyday life when a child notices centrifugal force is a car that turns quickly into a curve. Like the weight in the experiment, you are pushed outwards.
