The best scientific experiments for children. Physics, chemistry, biology

The first part of the book is devoted to observations in nature and experiments that will help to understand and explain what is happening: why does the tree always grow up, the woodpecker does not fall from the vertical trunk, and the snail from the smooth wall? Observe natural phenomena and put the experiments by modeling them.
The second part will reveal the world of chemistry to you: what are the transformations of substances and what are they consist of, what solutions are and why this science is so important. There are simple, but very interesting experiments, but there are those that need to be put only in a chemical laboratory or with adults. You will have to prepare for the experiments: you will need overalls, because you are real chemists!
In the third part you will find out what different microorganisms surround us, how they are arranged, where they can be found and how to consider. You will see that although they are tiny, their meaning is difficult to overestimate.
Authors of the book, Tomislav Senchansky and Tatyana Mikhailov-Krstev, are scientists. They not only conduct scientific research and teach students, but engage in children, helping them to discover an amazing world controlled by the laws of nature.
