Book excerpt: 2024 AAAS/Subaru SB&F Prize for Excellence in Science Books Winner Pediatrician Dr. Betty Choi invites kids ages 8 and up to explore the marvels of the human body with lively hands-on projects and activities, including shaping bones from salt dough, creating a moving model of the eyes, crafting a 3d skin model, making a blow-up model of how a bicep muscle contracts, tracing capillary action, and even setting up a working model of the urinary system to show how pee is produced. Packed with colorful diagrams of how each major body system works, fun facts, and easy tests that kids can use to learn about and evaluate their own body functions—from touch sensitivity to colorblindness, taste perception, lung capacity and more—The Human Body Learning Lab makes biology more exciting and engaging than ever.
