You may have seen the recent commercials showing a child raising flags representing America’s standing in school ranking world-wide. I came across an article for the same campaign that shared some striking, but unfortunately not surprising, statistics. According to the “One Nation Left Behind” program, 20 countries outscore the US in science education and 93% of US middle school teachers have little or no science training.
As standardized testing becomes key in schools nation-wide, the decline in science education becomes widely apparent. The Strong American Schools Website offers more staggering statistics and eye-opening quizzes that help drive home the point that our children are not receiving enough science education. Check it out and be prepared for some shocking results.
However, the One Nation Left Behind campaign is committed to creating awareness about the growing education problem in America… from science, to math, to English.. and offers opportunities to get involved in your community.
The BBC UK called our offices yesterday to get permission to use the Inside the Soda Can experiment, that I’ve done on 9News, for Chris Jeavans “plastic-free” blog. Chris is trying to live for one month without using any plastic products. As the soda can experiment proves, Chris is finding that this may be a harder task than she once expected! When you perform this experiment, you will find that aluminum cans actually have a plastic liner, which prevent the acid in pop from eating away at the metal can. Mark that up as one more product Chris will be eliminating from her life this month! Be sure to check out Chris’ blog for some great info on what it means to “go green” in this consumer-driven world. It’s always fun to see our experiments making it around the world.
It’s probably the most asked question we get… “How exactly does that experiment with the Mentos and Diet Coke really work?” From the outset (nearly eight years ago), we hypothesized that the exploding soda was a physical reaction, and the key factor in the release of carbon dioxide was the microscopic pits on the surface
of the chewy mint. However, there was no real scientific study that anyone could point to as the definitive answer… until now. In the June issue of the American Journal of Physics, Tonya S. Coffey, an assistant professor of physics and astronomy at Appalachian State University, in Boone, N.C., and her team of fearless physics students reported on the ingredients, temperature dependence, duration, and other parameters of the suddenly famous Mentos-Diet Coke reaction.
There has been considerable debate over gum arabic (found in the coating of the mint) and the role it plays in the physical reaction. Coffey’s group was able to confirm that the surfactant gum arabic is a key component of the reaction: It reduces surface tension, thereby
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 …
