Does your child wonder why hand warmers get hot, why ice packs feel cold, or what makes a fire burn? This clearly written nonfiction guide unlocks the fascinating science of heat and energy - one step at a time - using plain language, real-world examples, and concepts matched to young learners.

Inside this guide, young scientists will discover: What thermochemistry is and why it matters in everyday lifeThe difference between exothermic reactions (like burning wood) and endothermic reactions (like dissolving salt)How scientists measure heat using enthalpy and calorimetryWhat activation energy is and how it controls how fast reactions happenThe three ways heat travels - conduction, convection, and radiation - with relatable examplesWhat happens to energy during phase changes like melting and boilingAn introduction to entropy and why some reactions happen on their ownHow thermochemistry connects to cooking, weather, the human body, and moreWho this is for: Parents, teachers, and homeschoolers looking for a focused, grade-appropriate introduction to thermal energy and chemical reactions for readers ages 8 to 12. Each chapter builds on the last, making complex ideas accessible without oversimplifying the real science.

Perfect for: Curious readers in grades 3 through 6 who love scienceHomeschool chemistry and physical science unitsClassroom supplemental reading and STEM enrichmentA thoughtful gift for a young science enthusiastIf your child has ever asked why things get hot or cold - this is where the answers start.
