Science “Left Behind” in American Schools

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.

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 … (more...)

Experiment of the Week Travels to Germany

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 … (more...)

Cornstarch Walk on Water - Get a Really Big Bathtub

The final step is to drive the cement truck filled with 2,500 pounds of cornstarch and 250 gallons of water to the back lot at the Ellen Show and pour the goo into a giant bathtub - 7 feet long, 3 feet wide and 2 feet deep. It's also a good idea to have your oobleck mixing experts change their clothes and spend the next 4 hours mixing the goo by hand to ensure the perfect consistency right before the tub gets moved on stage. How do you move a tub that weighs about 6,000 pounds? Using a forklift, of course. It's also a good idea to find someone in the audience who you've never met and trust that you won't let them sink into a pit of cornstarch goo.

Ellen DeGeneres Wants Giant Smoke Rings!

It's official... I'm flying out to be a guest on the Ellen DeGeneres Show next week. Back in April of 2006 when a producer on the show originally contacted our office, I asked for your suggestions on experiments to do with Ellen. Lots of people suggested my Smoke Rings demo and Ellen might have taken your suggestion (hint, hint). Let's just say that our office was filled with lots of smoke today as someone practiced shooting cups off of everyone's head. We're told that the air date will be next Friday, September 21, 2007. More to come.
