experiments
  • 1 - Appearance

    experiment "Appearance"

    One after the other, a spatula full of glucose, table salt, gypsum, starch, sand and citric acid is closely examined under a magnifying glass.


  • 2 - Solubility in water

    experiment "Solubility in water"

    The students check the solubility of the different substances with water and record this in writing.


  • 3 - Electrical conductivity

    experiment "Electrical conductivity"

    Using an electrode bridge that the students build themselves, the electrical conductivity of the liquids prepared in the previous experiment is checked.


  • 4 - Behaviour when heated

    experiment "Behaviour when heated"

    The materials are heated by the students with the help of the stand materials and the Bunsen burner and then examined.


  • 5 - Distillation of orange juice

    experiment "Distillation of orange juice"

    The students investigate the distillation of orange juice and can observe exactly what happens in the Erlenmeyer flask, the angle of the glass tube, the hose and the test tube.


  • 6 - Distillation of port wine

    experiment "Distillation of port wine"

    The students investigate the distillation of port wine and can observe exactly which processes take place in the Erlenmeyer flask, in the glass tube angle, in the tube and in the test tube.


  • 7 - Aggregate states

    experiment "Aggregate states"

    The students investigate the different states of matter with the help of ice cubes and a spirit burner.


  • 8 - Components of water

    experiment "Components of water"

    With the help of a water decomposition apparatus, students can investigate the components of water.


  • 9 - Electrical conductivity of water

    experiment "Electrical conductivity of water"

    The students investigate the electrical conductivity of tap water, distilled water and mineral water.


  • 10 - Saturated Solutions (1)

    experiment "Saturated Solutions (1)"

    The students observe the behavior of sugar in water. How does sugar dissolve in cold and warm water? What happens to both solutions when they are heated?


  • 11 - Solubility of different substances

    experiment "Solubility of different substances"

    Through this experiment, the students learn about the solubility of substances in oil and in water.


  • 12 - Melting temperature

    experiment "Melting temperature"

    The students learn about the melting temperature and can use the experiment to find out for themselves what the melting temperature of the individual substances can depend on.


  • 13 - Sand / iron powder

    experiment "Sand / iron powder"

    The students can use the experiment to observe the behavior of sand and iron powder in relation to the test tube with the magnet.


  • 14 - Sand / salt

    experiment "Sand / salt"

    Students investigate separation processes of substances.


  • 15 - Distillation of copper-sulphate-solution

    experiment "Distillation of copper-sulphate-solution"

    The students investigate the distillation of a copper sulfate solution and can observe exactly which processes take place in the Erlenmeyer flask, in the glass tube angle, in the tube and in the test tube.


  • 16 - Detection of water

    experiment "Detection of water"

    Using the spirit burner, students investigate the appearance and temperature of copper sulfate with and without water.


  • 17 - Processes of solubility of sugar

    experiment "Processes of solubility of sugar"

    In this experiment, the students can investigate the dissolution processes of sugar in hot and cold water.


  • 18 - Saturated solutions (2)

    experiment "Saturated solutions (2)"

    The students observe the behavior of table salt in water. How does the salt dissolve in cold and warm water? What happens to both solutions when they are heated?
