UV Beads Help Students Understand the Importance of Sunscreen
You might have seen t-shirts or special jewelry (beads) that changes color in sunlight. UV Beads look like ordinary white beads used to make a craft project, but embedded in the plastic is a special pigment that changes color when exposed to ultraviolet light. The color change takes place in just seconds - almost like magic. Mrs. Bratteli’s Third Grade Class from Aikin Elementary School in Paris, Texas, used the beads as a way to see if sunscreen lotion really blocks out harmful ultraviolet light from the sun.
We did an experiment with your UV beads and sunscreen and the types were 10, 30, and 50 SPF. We put them each on a foam plate and had a nothing plate. [control—no sunscreen] They changed colors exactly how they were supposed to, but the 50 you couldn’t see. Read the full experiment write-up.
But, like all good experiments, these third graders discovered something else…
We left them all over the weekend and here are our results. The SPF 50 sunscreen also ate through the Styrofoam plate! The spf 10

It’s great to get emails with this subject line… My science fair project placed 1st from an idea from your website! Grant Smith is a 4th grader at S&S Elementary in Sherman, Texas. The “S&S” two small towns, Southmayd and Sadler, are approximately one hour north of Dallas. Grant used our website as a resource to expand on the idea of the 
Project. I proved that Ivory Soap has air inside of it by showing it floats and expanding it in the microwave. Last week I placed 1st in the 4th Grade that earned me the “Chief Scientist” Certificate. I am very proud of it. I wanted to tell you thank you for your cool website. My teacher loves going to your workshops and showing us your videos too. We learn a whole lot from your website, kits, and books.
