The water cycle in nature, magnetic board game
A set of 44 colorful elements that are 100 percent magnetic because they are printed on full magnetic foil (not glued with pieces of magnetic foil). They are designed to present the water cycle in nature on any magnetic surface (metal, school board, etc.). An interesting additional element of the set is a human silhouette on which the water content of the human body is marked in blue lengthwise.

Water circulation in nature - simulator model with lamp
Three-dimensional model made of plastic, depicting a fragment of the natural lay of the Earth's surface, including high mountains, and presenting "live" water circulation in nature. The simulation is done by placing ice under a cloud-shaped container (the temperature level at these heights), and then bending a lamp (e.g., an office lamp with a flexible arm) over the model to imitate the sun and its thermal energy. Both of these produce an effect similar to that in nature - water begins to circulate in this miniature environment, rain falls from the cloud, mountain streams form and water runs down the slopes of the mountains, then evaporates in reservoirs and water vapor rises upwards..., just like in nature The set comes with a lamp painted yellow with a flexible arm to make it easier to tilt it over the model with a traditional bulb, that is, not only illuminating, but also emitting the necessary heat here. Dimensions 40x30x15 cm.

Experiments with water - properties and curiosities, experimental set with laboratory equipment
The set helps to understand the amazing world of water, its secrets and properties, thanks to 35 experiments easy to perform in school conditions, described step by step. The kit contains the laboratory equipment necessary for the experiments and such as is used in chemistry laboratories - so the package is also a good introduction to the world of scientific research. The accompanying manual includes cards for 35 carefully designed experiments with water, together with a discussion of the results of each experiment and conclusions, as well as an indication of the expressions and concepts students will learn during and after performing a given experiment. The purpose of this experimental set is to learn about the properties of water, its complex nature and interesting characteristics that continue to amaze scientists and continuously affect our lives and our planet - remember that humans are made up of over 60% water and 75% of the Earth is covered by water... These 35 experiments are designed to make students aware of how these seemingly simple molecules - H2O - exhibit a multitude of interesting characteristics under different conditions. Water is encountered everywhere in our daily lives, and in the school curriculum it appears in every subject, so it's worth getting to know it better. The entire kit comes in a 2-tiered, resealable plastic container with sponge inserts that have cut-out slots for kit components so they can be easily and safely removed and stored.
