Demonstrate The Presence Of Ultraviolet Light With Color-Changing Beads
Your students can't see ultraviolet rays, but they'll know they're there with these special beads. Have your class make bracelets or necklaces while the beads are white, and then wear them outside. When they see that the ultraviolet-sensitive pigment changes colors, even on a cloudy day, your young scientists will understand that UV light is around them, even when they can't see it. The beads will revert back to white when they are no longer exposed to UV rays and will change over and over again without fading for use in many cool science experiments. Includes approximately 1,000 beads that change into assorted colors.
We Know Standards
In the U.S alone, nearly 30% of educational standards are overhauled, revised or edited each year. Tracking these changes demands the full-time expertise and we have the tool to manage those standards, so you can trust us as the leader in standards alignment. Correlations are made for all State, National, and Common Core Standards. In addition, we have Head Start standards for early childhood. And most recently, we’ve added both National STEM Standards and Next Generation Science Standards (NGSS).Learn More
