Get ready to amaze your students with our sensational Green Ultraviolet Beads, a game-changing educational tool that's sure to spark curiosity and excitement in the classroom! These miraculous beads have the incredible ability to change color from white to green when exposed to ultraviolet light, and then revert back to their original white hue when returned indoors. But what triggers this remarkable transformation? Is it the humidity, temperature, or perhaps the fresh air? The secret lies in the specialized pigments embedded within the beads, which react to the UV rays emitted by the sun, even on overcast days.

Not only do these astonishing beads respond to natural sunlight, but they also react to most classroom UV light sources, making them an ideal teaching tool for exploring the fascinating world of ultraviolet light. By stringing the beads onto a pipe stem or rawhide strip, students can create their own UV light-detecting bracelet, a fun and interactive way to raise awareness about the importance of UV protection.

But that's not all - our UV beads also double as a valuable resource for scientific investigation. Use them to test the UV-blocking effectiveness of various materials, such as sunblock, sunglasses, windows, and more. The possibilities for experimentation and discovery are endless! And with our comprehensive lesson activities, you'll have everything you need to get started.
