Atoms are the essential building blocks for everything in the universe. From the water people drink, to the hair on our heads, to the books we read—they’re all made of protons, neutrons, and electrons. Ellie is an electron. She’s attracted to protons, has very little mass (smaller than the period at the end of this sentence), and powers the electronics we use every day! Why does static electricity build up and zap people in the winter? Because of electrons like Ellie. Who can race around the planet in eighteen seconds? Electrons like Ellie! It doesn’t matter how small you are—with enough energy, Ellie proves that just about anything is possible. A My First Science Textbook title, Electrons shows readers a subatomic world through the eyes of a relatable personality.
