UV Color-Changing Beads
Learn about the presence of ultraviolet light with our color-changing bead set from Steve Spangler Science. Just because we can’t see ultraviolet rays doesn’t mean that they aren’t there! With our special UV-detector beads, kids will learn that they are indeed present — even on cloudy and overcast days! Our special beads are a fantastic activity for older elementary children.
UV Beads = Hours of Fun
With our UV detector beads, you can make bracelets or necklaces while the beads are white. When you wear them outside, the ultraviolet-sensitive pigment will change the beads’ color from white to a fun color assortment of blue, green, orange, purple, red and yellow. Our UV detector beads are so sensitive that they’ll detect the presence of UV rays — even on a cloudy day! Your young scientists will learn that UV light is all around them, even when they can’t see it. Bring the beads inside and they will revert back to white since they are no longer exposed to UV rays. These UV beads will change over and over again without fading.
The UV Color Changing Bead Lesson
Ultraviolet (UV) light is the invisible radiation that will give you a sunburn and injure your eyes if you’re not careful. UV Color-Changing Beads harness the power of ultraviolet rays to change colors — right before your eyes. Use the beads to teach kids about the ultraviolet radiation and the care that needs to be taken to prevent the skin damage it may cause.
UV Beads as a Fun Science Fair Experiment
To turn the UV beads into a science fair project, you have to change something (identify a variable), run some more tests and make some comparisons. Find several different types of medicine bottles and test to see which one is the most effective in blocking the beads from the damaging UV rays. Other ideas are to examine the UV-blocking powers of different sunglasses. You can also test different sunscreens by placing the beads in a zipper-lock bag and covering the bag in sunscreen.
Remember, you have to keep all other factors the same. Use the same light sources and the same number of beads. There are many ways to use these UV beads for a science fair project. We have written up a sample science fair experiment called The Sunscreen SPF Test that walks you through a project step by step. If you are interested in a simple, straightforward and quick science fair project, be sure to check it out. It doesn’t do the work for you; you wouldn’t want that anyway, right? It does, however, provide you with a template to follow to ensure that you use the scientific method, control your variables and document your discoveries!
