The International Junior Science Olympiad selects fifteen-year-olds who can think across disciplines — problems that demand biology, chemistry, physics, and mathematics simultaneously, under competition pressure. Dr. P.K. Joshi has spent years developing questions for India's IJSO selection process, and this book grows directly from that work.
But this is not a question bank. Each article goes behind the problem: the thinking that generated it, the detailed logic of the solution, and the connected ideas a strong student should know around it. Some assumptions simplify reality — that is made explicit — but none are unrealistic, and the analysis built on them holds. For Class IX and X students and their teachers, this is an introduction to the kind of complex, multi-concept problems that the Olympiad demands and that standard curricula rarely attempt.
-:ABOUT THE BOOK:- International Junior Science Olympiad (IJSO) is a competition in science for students who are fifteen years old. IJSO aims to promote interest in science among school students, exposing them to problem solving, critical thinking and experimentation. Over the years IJSO has positively impacted science and mathematics education at school level. Short articles presented in this book are based on the questions prepared for the selection of IJSO students who represented India at the International competition on several occasions. However, the articles go beyond the question-and-solution format by describing the thought process behind the questions, the detailed explanation of the solution and many other related descriptions. Hence, some of the assumptions in the topics deviate from reality but are not un-realistic and the further analysis is based on those simplistic assumptions for school children. The target audience is the class IX and X students and their teachers with the purpose of introducing them to challenging topics of nature which involve several different concepts of science and mathematics, often at the same time.
