Science is built on a foundation of careful thinking, precise language, and rigorous methods — and understanding the key terms and concepts of scientific inquiry is essential for every young scientist. This engaging book introduces young readers to the essential vocabulary of science, from observations and inferences to hypotheses and theories.

Students will discover the difference between an observation and an inference, learn how scientists form and test hypotheses, and explore what it means for an idea to become a scientific theory. They will learn about the scientific method, the importance of evidence and data, and how scientists communicate their findings to the world. The book also covers key science terms like variable, experiment, conclusion, and peer review.

Aligned with physical science and scientific inquiry curricula, this book is an ideal resource for school libraries, classrooms, and independent learners. A comprehensive glossary, science vocabulary activities, and discussion questions help students develop the scientific literacy they need to think critically and engage with science throughout their education.
