Developing tasks in physics for schoolchildren of grades 5-9

Can you solve the problem using a minimum set of physical formulas or without resorting to calculations, more difficult than ordinary arithmetic actions? In this book, the author offers text problems in physics, solved just like that with his inherent ease and grace. The plots of tasks will attract the attention of children with an abundance of fairy -tale and fantasy plots, joking and humorous shades, the participation of characters in Russian folk tales. The book will be interesting to both schoolchildren who have already begun to study physics (grades 7-9), and the guys who are preparing for this (grades 5-6) The texts of tasks contribute to the development of the child’s figurative thinking, the search for unexpected answers to questions that seem intuitively clear even an adult reader. The materials of the book, in addition, can be used by teachers in the work in the lessons, as well as parents for classes with children at home.
