Objects that surround us come in very different sizes, so a person has come up with units of measurement - to measure everything and compare. In this book we will look at different objects and present them as much as little on the scale of the universe! Let's start with the smallest of them: microorganisms, cells of living organisms, atoms, electrons, then consider larger objects: various structures, mountains, seas, oceans, and end up with giant planets and asteroids. All chapters of this book are supplemented with original experiments, which the child will be able to do on his own.
