Experiments with Water – Properties and Fun Facts, Laboratory Equipment Set

Experiments with Water – Properties and Fun Facts, Laboratory Equipment Set

The set helps students understand the amazing world of water, its secrets and properties, through 35 experiments that are easy to perform in school conditions, described step by step. The kit includes laboratory equipment necessary to carry out the experiments — the same equipment used in chemical laboratories — making the package a good introduction to the world of scientific research.

The included manual contains cards for 35 carefully designed water experiments, with discussions of the results of each experiment and conclusions, as well as explanations of terms and concepts encountered by students during and after each experiment.

The aim of this experimental set is to explore the properties of water, its complex character, and interesting features that continue to astonish scientists and constantly influence our lives and the life of our planet — remember that the human body consists of over 60% water, and 75% of the Earth is covered by water…

These 35 experiments are designed to show students how these seemingly simple molecules – H₂O – exhibit a wealth of fascinating properties under different conditions. We meet water everywhere in everyday life, and in the school curriculum it appears in every subject area, so it is worth getting to know it more closely.

The whole set is delivered in a two-level plastic container with sponge inserts that have cutouts for the set elements, so they can be easily and safely removed and stored.
