Give your kids a creepy, crawly chemistry kit they’ll love! The National Geographic Amazing Worms Chemistry Kit comes with everything your children need to conduct five unforgettable experiments. They’ll make glow-in-the-dark worms, color-changing worms, worm eggs, and more! A detailed experiment guide takes you step-by-step through each experiment and includes insight into the polymer science and chemical reactions that make this kit so much fun! 5 awesome chemistry experiments that explore the world of polymers! The experiments in this kit demonstrate the principles of: •Polymer reactions (molecule chains cross-linking, present in all experiments) •Phosphorescence (make glow-in-the-dark worms) •pH indication and color-changing (color-changing worms) Enough materials to do experiments more than once, and includes all the tools you need: •Glow-in-the-dark worms •Color-changing worms •Worm eggs •Giant Worm eggs •Dehydrated worms
