What makes a good science fair, a good school, a good science lesson? Hands-on exploration and discovery are a great start and never forget to instill a sense of wonder and curiosity in our students.

Without enthusiasm and even a little risk sometimes, learning can quickly become a dead end street. Where there’s boredom, there’s danger.

No worries about any of that here, though. The teachers who have contributed to this week’s Carnival of Education are all of those good things… and MORE.

Let’s visit some of them, shall we? Read the rest of this entry »

Sean Moncrieff is the host of the Afternoon Show on Newtalk 106-108 fm in Ireland. This nationally syndicated show features news stories ranging from the serious to the zany… maybe that’s why they called. While waiting for my segment, I listened to the show and quickly realized how much I want to speak again in Ireland. I first lectured at the Irish Science Teachers Association in 1997 and again in 2000. I shared a few science demos and they taught me the finer points of drinking lots of Irish beer. Here’s my interview with Moncrieff.

Just look at these pictures from Science in the Rockies last year and you’ll see why we don’t consider this your typical summer science workshop for teachers. Do not plan to attend Science in the Rockies 2008 if you are motivated by PowerPoint presentation, like quiet reading time from an outdated science text, hate to get your hands dirty, or have a fear of flying potatoes. One teacher described Science in the Rockies as the science methods class she never had but really needed!

Science in the Rockies 2008 is scheduled for July 9-11 in Denver at the Sheraton Denver West conference center. Registration is still open, but as of this morning there are fewer than two dozen spots available. Years ago, teachers who took this workshop called it a “science boot camp” - an intensive experience designed to inspire, motivate and move you into action… and the concept stuck. This boot camp is for K-5 teachers who need creative science integration strategies… who are tired of trying to “squeeze” science into their already packed teaching schedule… and who want to make science even more fun and meaningful in their classroom.

Join us in Denver in July for a truly one of a kind experience.

Robert Woodhead is always looking for a new challenge with his Casio EX-F1 camera. I found Robert’s first Mentos Geyser reaction on Gizmodo using just a roll of Mentos and a bottle Diet Coke. Watching the reaction at 1200 fps is truly amazing. Robert found a willing subject (the kid running from the exploding bottle) and sent us this video. Huge thanks!

If you haven’t seen the Mentos Slow Motion Video from the people at Perfetti Van Melle, watch it! At 2,000 frames per second, you can actually see the carbon dioxide bubbles forming on the nucleation sites.

If you couldn’t get enough of flying potatoes the first time, the nice people at the Ellen Show are rerunning the show that originally aired on April 15, 2008. The featured experiments include the Baby Diaper Secret, Fire Water and several versions of our potato guns (okay… call them “launchers”).

There’s a sneak peek video just posted on the Ellen Show site with the Dancing Fire demo and the last part of the shooting potatoes segment. If you have a second, post a comment on the show site.

All this week on TV, I had the opportunity to get a behind the scenes look at Denver-based companies who each have a cool science twist to their business. The scientists at Gates Corporation invited our cameras on a tour of the hydraulic testing labs at Gates where they demonstrated how engineers test high pressure rubber hoses for commercial use. During the segment, Joel Edwards, Vice President of Fluid Technology & Product Development and Larry Kachinski, Senior Lab Engineer pressurized a hose rated to 6,000 psi with a safety factor of 4:1. The loud burst produced a perfect rupture at nearly 28,000 psi!

Anything that goes bang is fun, but… I was most impressed to speak with Joel Edwards, VP of Product Development, and his engineers who all share the same passion for getting students K-12 excited about careers in science and engineering.

Mixing 2,500 pounds of cornstarch with the kitchen mixer just didn't work, so we had to find a cement truck… and a very cool cement truck mixing guy. Oh, and you also need three people who know exactly what the cornstarch mixer should feel like when it's perfectly mixed. Jeff, Carly and Renee served as the mixologists while I called the producer at the Ellen Show to let him know that we were ready to roll to the studio.

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. Watch the Cornstarch Water Walk Video View more photos at The Science Behind the Goo - Photos from the Ellen Show

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.
