Luminous Science explores the world of light and bioluminescence, including a 48-page book, 38 card model pieces, and a UV light-up pen to build projects like a glow-in-the-dark lava lamp and viewing box. Circuit Science teaches the fundamentals of electricity through 6 electrical circuit experiments, featuring two LEDs, metal circuit tape, a battery holder, and 14 card model pieces to build projects like a light-up lantern. Both sets are designed for ages 8 and up, providing hands-on learning through building and experimentation.
