Learning through experience is key for true understanding. This clever series features numerous safe, accessible experiments using easy-to-find materials and step-by-step instructions. Colorful illustrated characters, including Professor Albert and Greg the Robot, accompany learners and help clarify important points that readers should comprehend. Each experiment includes difficulty and dirtiness ratings so learners know what to expect as they enter their lab. Disgusting chemistry (slime!), light and color, electricity and magnetism, and optical illusions are the high-interest topics that will motivate budding researchers to unravel the secrets of elementary science.
