beads.jpgYou 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 did a little eating through the plate, but the 30 did not do a thing and neither did the nothing. Do you think using 50 and 10 SPF is dangerous or would effect us?

Here’s a great example of kids doing real science and making new observations and discoveries. As you might imagine, there’s nothing wrong with the kids’ sunscreen, but what they did discover is that something in the sunscreen reacted with the Styrofoam plate. It’s well known that fingernail polish remover (dilute acetone), spray glue, paints and other household chemicals react with Styrofoam, causing the polystyrene to quickly dissolve on contact. The students discovered something in their brand of sunscreen that caused a similar reaction.

bratteli.jpgHats off to Nancy Bratteli and Nicole Sumpter, third grade teachers at Aikin Elementary in Paris, Texas, who do a great job of getting their students excited about science throughout the year. Halloween is especially fun for these two when they host Aikin All-Day Science… and the kids go crazy. One of the prevailing themes in my training seminars is the need for turning ordinary activities into unforgettable learning experiences… and these teachers are doing it. Nice job.

This story came across my Google alerts today from the crack team at ABC News… “Science of Mentos-Diet Coke Explosions Explained.” My fingers couldn’t click on the link fast enough. New research finally explains this amazing phenomenon? Here’s the opening sentence of the story…

The startling reaction between Diet Coke and Mentos sweets, made famous in thousands of YouTube videos, finally has a scientific explanation. A study in the US has identified the prime factors that drive the fizzy plumes from Coke bottles: the roughness of the sweet and how fast it plummets to the bottle’s base.

What… this is the big discovery? The Mentos chewy mints have a rough surface and they’re heavy? Well, they’re absolutely correct and they confirmed the original Mentos Eruption explanation published back in 2005. Tonya Coffey, a physicist at Appalachian State University in Boone, North Carolina said, “This was a good project for my students to study because there was still some mystery to it.” Hats off to Coffey and her students for publishing her findings and bringing peer review to the Mentos Geyser experiment.

However, it was nice to have someone else confirm our findings that either fruit or mint Mentos work equally well. “The results showed that Diet Coke created the most spectacular explosions with either fruit or mint Mentos, the fountains travelling a horizontal distance of up to 7 metres.”

It was probably most fun to read the comments on the ABC News blog. What questions or “mysteries” about the Mentos reaction would you like to ask?

So, America throws it back to the Europeans… from Louisville, KY to Turiba University in Latvia there is a new Mentos and Diet Coke World record. On June 19th, 1,911 students from Business University Turiba in Latvia launched an amazing geyser eruption and landed themselves in the Guinness Book of World Records, just over a month after students at Male High School in Kentucky launched 1,800 simultaneous geysers to earn their own world record status. The Latvian University students were celebrating the school’s 15th anniversary, and what better way to celebrate than with Mentos and Diet Coke. Check out the video of this monumental occasion. Now, who’s next…

It’s great to get your e-mails and photos of your children and students doing the science activities featured in our Experiment of the Week. These photos are from Sheila Allen, just one of a number of great teachers in the Department of Defense Schools at Ramstein AFB in Germany. Sheila writes…

“Well today was the big day and boy did the children have fun!
I think my favorite was the Expanding Ivory Soap activity, and I picked just the right kid to trick with the Do Not Open Bottle. We were doing an A-Z countdown to the end of school and so for E we did experiments, and we thought your activities really hit the high point for us! There are 9 kindergarten classes at Ramstein Elementary school (K-2) , and it is a good place for science to happen.”

Sheila Allen and her team of mad scientists are a great example of how early childhood teachers are having an incredible impact on the science concepts that young children are being exposed to in the early years of their education. Over the last 15 years, I’ve seen countless examples of early childhood teachers working hard rewriting their science curriculum to include more hands-on science experiences that prompt children to ask “what if” questions and give them the scientific tools to test out even the simplest hypothesis. Sheila Allen and thousands of teachers like her are working hard to meet and exceed the National Science Standards through their innovative teaching methods, they have a passion for learning and an ability to inspire young children… even if that means getting a little messy.

Not to be out-done by Europeans, students at Male High School in Louisville, KY, set off 300 more geysers than the previous record-breaking effort just a few months ago in Belgium. School officials thought exploding Diet Coke and MENTOS would be a great way for students to blow off a little steam before finals and celebrate a great school year. The students were recognized by the Guinness Book of World Records as the new official record holders with 1800 geysers. All proceeds from the event were donated to the Ronald McDonald House. Congrats to Male High School students… now who will be next in the race for a new geyser world record?

Henny Penny Preschool has a Blast with Science!

There is a waiting list for parents who want to enroll their children in the Henny Penny Preschool, and there is a good reason for that: Amy Dolley has created one of the best preschool environments I’ve ever seen! Amy doesn’t even have to advertise… word of mouth is what sells the Henny Penny Preschool.

Amy wasn’t comfortable with the kind of preschool her own children had attended, so she decided to create a livelier, more “hands-on” environment when she quit her Kindergarten and 1st grade teaching job and started her own preschool right in her home.

She knew she could do it, too. After all, as the Story Lady, she had built her “clientele” from five children –three of which were her own – to over fifty kids! Obviously, Amy knew how to reach and teach small children, and with her own school, she knew she would get to do “what she wants, how she wants.” And what Amy wanted to do was create an environment that allowed small children to run and play, to get muddy and wet, and to learn about the world around them in ways that would be remembered and passed along to others! “Dogs, mud, and hands-on” are some of her secrets for getting young children interested in science.

Amy was worried about the science lessons, though. She had never felt comfortable teaching science because she didn’t know then what she knows now:you don’t have to be good at science to love it, and when you love science, that attitude is passed along to your students!”

Amy’s husband, Craig, as “Mr. Wiz,” volunteers at the preschool and presents a science experiment each week, and when I say “presents,” what I really mean is “encourages the children to put their hands on things, get messy with it, laugh and chatter with excitement, and take the lesson home to the dinner table to share with siblings and parents.” To quote Amy, “We made our own curriculum because it’s important for kids to move, grow, explode, and fly.”

That’s the real deal, you see. When a child is so excited about what he has learned that day, that he can’t wait to get home and share it with family and friends, that’s genuine education. Craig and Amy Dolley’s students almost always go home to chatter excitedly about what Mr. Wiz helped them do that day.

The Dolleys credit our own SteveSpanglerScience.com website with providing a launching pad for many of their science lessons.

Amy says that “. . . Steve did the tough part – we just follow his lead!”

The Dolleys discovered Steve Spangler Science while surfing the internet for science ideas, and once they found us, they felt as though they’d struck gold. Amy says that she spent hours on our website that first day, watching video after video, clicking links and taking in all in.

Craig Dolley, as Mr. Wiz, was determined to have a science curriculum that excited the kids, not the typical demonstration/worksheet curriculum so many schools still have today. Craig wishes ALL public school teachers would learn how to teach the Steve Spangler way – with enthusiasm, joy, and obvious love of their subject areas. Craig understands that a teacher learns along with the kids, and that if there is too much explaining and not enough hands-on, not many lessons will be taken home to be demonstrated at the dinner table or in the back yard.

“Even the kids’ parents get excited when they see that Mr. Wiz is at the school today,” says Craig. “They know something wonderful is going to happen! And then the kids go home and gather their friends together to teach them what Mr. Wiz taught them that day. That’s what it’s all about!”

It’s not just the kids who take the experiments home to share, either. Amy employs several other teachers in her preschool, and they take the experiments home to THEIR kids, too!

Craig and Amy both say that “Steve made our jobs easy.” This hands-on approach is much more vital than a regular school textbook, and I’m sure many more students than just the Dolley’s daughter have a Harry Potter book under that boring science book.

Amy says that “The science is easy now; I used to dread the science lessons, and now I love them. It saddens me that so many kids don’t get this kind of lesson in their school, because no one is ever too old for hands-on! Teaching science the Spangler way isn’t even that hard; it’s mostly FUN! Our daughter is jealous because, as she puts it, ‘mine is so boring, and you get to have fun all the time.’”

Both Craig and Amy agree that the Spangler science activities “. . . relax the whole day! Everyone is more laid-back after participating in a fun and exciting science activity, because it’s so important to both body and mind to be allowed to just ‘let go’ sometimes.”

“Steve really does a service to parents and teachers; it’s been truly amazing at our preschool this year,” says Amy. “Our students are so young that it’s not really why or how that matters; it’s that they LOVED THE SCIENCE, and wanted to do more and more of it.”

Amy’s favorite experiment is the Mentos Geyser, and she saves that one for the last day of school. She has discovered that the cheaper the cola, the better the results. As for the childrens’ favorite experiment, “Each is a favorite to a different child.”

Amy and Craig “Mr. Wiz” Dolley, and even their dog, all work together at the Henny Penny Preschool to make sure their students go home every day with their heads full of new knowledge, their bodies exercised and rested, and their whole being full of the excitement of it all and the desire to share it with everyone they know.

Thank you, Craig and Amy, for allowing us to be a part of your world for a little while. Keep up the good work!

Lynn is a mother who decided, a year or so ago, to “unschool” her daughter, and her blog, A Life Worth Living, tells her readers how this is unfolding for her family in the UK.

Last April, Lynn found our link on a friend’s blog, clicked on it, and discovered us! ” . . . I went onto a website I had found that had a link to Steve Spangler Science, and found lots and lots of new experiments to do. . . some I have heard of before, some I haven’t. I also like the fact that you can watch a video clip of quite a lot of the experiments.”

Thank you, Lynn, for your kind words about our website!

I never cease to be amazed by what shows up in our e-mail inbox. Today’s video clip shows an intimate gathering of friends who are just conducting a little experiment with their cell phones - trying to pop popcorn using the combined energy from their cell phones. Take a look at the video and then keep reading…

The first thing Alyssa (one of our crack science editors at Steve Spangler Science) does is to search snopes.com Within thirty seconds or so, she uncovered this article debunking the popcorn myth. Snopes.com goes into great detail (far more than anyone I know of) about the origins and connected myths. If nothing else, it’s a great resource to check out those too-good-to-be-true e-mails. In the future, just copy the subject heading from your e-mail into the “search” at snopes.com and read away.

But… you’ll have to admit, the hoax video looks pretty darn good. Care to share any cool videos from your inbox?
