Experiments with water - properties and curiosities, experimental set with laboratory equipment

MACHINE TRANSLATION (not authorised yet)

The set helps to understand the incredible world of water, its secrets and properties, thanks to 35 experiments that are easy to do in a school environment, described step by step. The kit includes the laboratory equipment needed to conduct the experiments and the same equipment used in chemical laboratories - so the kit is also a good introduction to the world of scientific research.
The attached manual contains sheets of 35 carefully designed water experiments with a discussion of the results of each of them and conclusions, as well as an indication of the expressions and concepts the students learn during and after the experiment.
The task of this experimental set is to learn about the properties of water, its complex nature and interesting features that still amaze scientists and constantly affect the life of our and our planet - remember that man consists of more than 60% water and 75% of the Earth is covered by water...
These 35 experiments are supposed to make students aware of how these seemingly simple particles - H₂O - show a lot of interesting features under various conditions. We meet water every day, and in the school curriculum it is present in every subject, so it is worth getting to know it better.

The whole set is delivered in a 2-level, lockable plastic container with sponge inserts, which have cut-out sockets for the set elements so that they can be easily and safely removed and stored.
