Experiment set KINDERGARTEN 1 (Water)


The joy of experimenting

Every child is familiar with water, but it’s chock full of secrets. This experiment kit offers an exciting way to investigate them.

  • How can you get a ball of modelling clay to float or get a car across a river without a bridge?
  • How does the water cycle work and how does water get to our homes?
  • Why do bubbles form when water is heated and why do water droplets have such a strange shape?

These are just some of the questions that the enthusiastic young researchers get to the bottom of.

A dry workplace

Screwing rods into the bottom of the 11cm high storage box turns into a watertight tub. This means that only the inside of the box gets wet even when carrying out the fountain experiment. This can be easily emptied afterwards and wiped dry with paper towels.

Handout booklet

In line with the KINDERGARTEN 1 experiment set, there is a separate booklet for educators and pre-school teachers with detailed information on each experiment, didactic suggestions, and proposed solutions.
