Could the Human Brain Power a Light Bulb?: Discover the Science Behind Neurobiology

K-Gr 3–Part of the “Big Questions Answered” series, this engaging nonfiction title introduces young readers to the remarkable complexity of the human brain through a question designed to spark curiosity: could it power a light bulb? The book opens by explaining what a neurobiologist does before stepping back in time to show how early civilizations, including the ancient Egyptians, believed the heart—not the brain—controlled thoughts and feelings. From there, the text traces the scientific journey that led to our modern understanding of the brain. Clear, child-friendly explanations are paired with fascinating facts, such as the brain’s roughly 86 billion neurons—comparable to the number of stars in the Milky Way. Bright, inviting illustrations offer close-up views of the brain and its functions, including a multicolored depiction of different regions and the roles they play in thinking and movement. Contemporary applications, such as brain-controlled robotics and tiny wires that transmit electrical signals to nerve cells, are introduced alongside emerging concepts like artificial neurons, providing a forward-looking perspective without overwhelming young readers. The titular question is answered with nuance: the brain produces short electrical bursts rather than the steady flow required to power a lightbulb. The back matter extends the learning with record-breaking animal brain facts, engaging trivia, a glossary with pronunciation guide, and a QR code linking to free resources, including activity packs.
