Dynamite is highly explosive. This is because it's a chemical reaction waiting to happen. Chemical reactions happen all the time - even inside us! Reactants change to make new products. Explore physical and chemical properties of the substances that surround us in this explosive physical science book. From decomposition to acid-base reactions, fifth grade readers will learn about six types of chemical reactions; activation energy and hopping electrons; reactivity, catalysts, and inhibitors; physical changes of mixtures; and more through this high-interest informational text filled with vibrant photographs. Aligned to the Next Generation Science Standards, a hands-on "Think Like a Scientist" lab activity and a "Your Turn" page at the end of the book support STEM Education and provide young scientists with an opportunity to apply what they've learned in the text. Helpful diagrams and text features, such as a glossary and index, are also included to reinforce content-area literacy and improve close reading.
