experiments
• 1 - Frictional electricity

### experiment "Frictional electricity"

Static electricity or friction is a type of charge separation. This creates a charge difference on the different bodies.

• 2 - Forces acting between harged bodies

### experiment "Forces acting between harged bodies"

This experiment shows how charged bodies behave when approaching.

• 3 - Model of an electroscope

### experiment "Model of an electroscope"

The students build a pendulum from pieces of elderberry pulp and examine the electrical state.

• 4 - Electroscope

### experiment "Electroscope"

The experiment shows the change in the electroscope when its electrode is touched with an electrically charged plastic rod.

• 5 - Polarisation/induction

### experiment "Polarisation/induction"

The experiment shows the effects when the charged plastic rod approaches the uncharged plastic rod.

• 6 - Induction at the electroscope

### experiment "Induction at the electroscope"

The experiment shows the influence on the electroscope.

• 7 - Storing charges

### experiment "Storing charges"

The experiment examines the electrical state when a charged plastic rod touches a metal cup and a glow lamp inside the metal cup.

The experiment shows the effect of a pendulum piece with an electrically charged plastic rod.

• 9 - Magnetic action

### experiment "Magnetic action"

In this experiment, the magnetic properties of different metals are tested.

• 10 - Magnetic field

### experiment "Magnetic field"

The magnetic field is a special state of space in which electrically charged bodies are attracted or repelled.

• 11 - Forces acting between magnets

### experiment "Forces acting between magnets"

The force of magnets means that like poles attract and different poles repel.

• 12 - Magnetic induction

### experiment "Magnetic induction"

Magnetic influence refers to the magnetization of ferromagnetic materials. This happens when they come into a magnetic field strong enough to align their elemental magnets.

• 13 - Geomagnetism/compass

### experiment "Geomagnetism/compass"

The way a compass works means that the needle always points to the geographic north pole, which is the same as the physical south pole. Therefore, it can be said that the earth is a great magnet.

• 14 - Electrolysis

### experiment "Electrolysis"

Electrolysis is used to break down chemical elements under the influence of an electric current.

• 15 - Galvanisation

### experiment "Galvanisation"

In this experiment, the influence of a copper sulphate solution when an electrical voltage is applied is examined.

• 16 - Electrochemical element

### experiment "Electrochemical element"

In this experiment, the chemical processes occurring when the electrodes are immersed in the acidic electrolyte are observed.

• 17 - Electrochemical potential

### experiment "Electrochemical potential"

In this experiment, the chemical processes are observed using different substances when the electrodes are immersed in the acidic electrolyte.
