Follow step-by-step chemical reactions, explore the periodic table and learn all about chemistry's real-life applications from solving crimes to producing green energy.Chapters in this book include:IntroductionFind out what chemistry is, and the amazing things chemists have learned to do with it over the centruries.What's the world made of?Discover the basic building blocks of EVERYTHING around you, why they're always changing and how they join together.Journey into an atomThe smallest building block - an atom - is itself made of even smaller parts. Keep track of the 118 atoms we know about so far in a handly chart called the periodic table.Making connectionsChemistry is all about what heppens when atoms connect and make - or break - bonds with each other.Chemical reactionsYou can't see atoms, but how they behave can be spectacular. This is the fizzy, foamy, explosive world of chemical reactions.See, smell, taste, touchSome chemicals have a taste, smell or even a colour. Others form incredible structures and materials. Together they shape your experience of the world.Your bodyChemists are facinated by how the body works, and what to do when it doesn't - from diagnosing diseases to designing medicines.Keeping us safeWhat makes a good or bad chemical? Is there even such a thing? Find out about chemists working to keep us safe.Saving the planetThe Earth's chemical balance is changing. What can chemists do about it?SpaceThe universe is full of chemical secrets - including how our planet and its inhabitants came to be.What's next?What are some of the most exciting things chemists are working on right now? Might you join them one day?
