We have 144 eco-friendly, hands-on fun experiments organized by common themes/chapters. They immerse children in the enchanted world of science, where sometimes they will act as detectives by exploring our environment in order to find answers; at other times, they will be magicians and wizards, making volcanoes or creating mysterious colors; and at still others they will even be great Sci-experts, making observations, comparisons, and hypotheses. Each experiment was specially designed to provide the readers with a wide picture in which the concept is inserted, connected, related, and applied. These experiments have STEM activities, and are related to our everyday lives, our needs, and our senses, and also to the living and nonliving things around us. Children explore scientific concepts such as phase changes, energy types, matter properties, chemical and physical changes and sensory processes. They will also discover plants, and animals.
