Meet Atom, a tiny atom who's here to introduce you to the environmental impacts of chemicals. Atom introduces readers to natural cycles and how they're impacted by the byproducts of chemical reactions. Students will learn about human activity that disrupts natural cycles and contributes to air, water, and soil pollution. They'll meet the atoms and molecules that make up the Atmosphere's Most Wanted list and learn about ways that they can reduce their negative impact on the environment. A handy glossary also helps to define tricky words for readers beginning their chemistry journey.
