Students kit Primary chemistry


Why does the sugar in the tea vanish after stirring? Why do blobs of grease float on the top of the soup while the noodles sink to the bottom? Why does sherbet dropped into water create a lot of fizz? For children water is part of their everyday lives. And they notice and watch these phenomena. Some of them – how substances behave in water – can be explored with this box.
By mixing water with various substances and conducting experiments under varying conditions, the students can investigate how the substances behave and identify any similarities or differences. This develops a systematic, networked and sustainable way of thinking that also gets students making the right connections and coming to the right conclusions.
The experiments follow a common theme, becoming increasingly difficult as they go on.

experiments
  • 1 - Tea and sugar

    experiment "Tea and sugar"

    The first experiment is designed for students with no previous experience of experiments. It uses common household materials. At this stage, the topic reflects everyday experiences and is an introduction to acting and thinking scientifically.


  • 2 - Water and sugar

    experiment "Water and sugar"

    In this second experiment the students encounter the same phenomena, but with a stronger emphasis on laboratory-style work.


  • 3 - Water and sugar – with and without stirring

    experiment "Water and sugar – with and without stirring"

    These experiments look at conditions affecting solubility. Variations and follow-up options are described in the teacher guidance sections.


  • 4 - Water and sugar – warm and cold

    experiment "Water and sugar – warm and cold"

    These experiments look at conditions affecting solubility. Variations and follow-up options are described in the teacher guidance sections.


  • 5 - Water and sugar – in large quantities

    experiment "Water and sugar – in large quantities"

    These experiments look at conditions affecting solubility. Variations and follow-up options are described in the teacher guidance sections.


  • 6 - Water and various substances

    experiment "Water and various substances"

    These experiments look at conditions affecting solubility. Variations and follow-up options are described in the teacher guidance sections.


  • 7 - Water and salt

    experiment "Water and salt"

    This experiment revisits the theme of solubility before moving on to crystallization.


  • 8 - Water and urea

    experiment "Water and urea"

    This experiment lets students investigate the thermal changes that occur when certain substances are added to water.


  • 9 - Water and gelling agents

    experiment "Water and gelling agents"

    This experiment looks at the solidification of water caused by the addition of substances that form a gel.


  • 10 - Water and sherbet

    experiment "Water and sherbet"

    This experiment leads into a new chapter of Research and Explore focusing on “sherbet”.
