Preparation for standardized testing has taken a lot of the fun out of the classroom, but good teachers will find a way to sneak the fun back in. REALLY good teachers will sneak the fun back in and teach some awesome lessons at the same time!

Science teachers frequently say, “I love all the activities you do, like being able to make slime, or make water float in a bottle, but of the 220 activities you taught us, only a handful were allowed in my school curriculum. There just isn’t enough time for science because it’s not on the big test!”

A colleague went to her principal and asked: “If it is not in school time, but in private time, do you mind if I teach science?”? The principal agreed.

On average, an elementary teacher spends about 15 minutes per child per year on his/her birthday, and each year that time grows shorter. That’s why “Cup Cakes for Science” was born. The kids were offered a choice between a traditional party or a science party where the birthday child gets to be helper. After one party, the class was hooked, and they even asked for science parties for their brothers and sisters too.

Children are starving for science. It is sad when a teacher has to find sneaky ways to put science back in the curriculum, but if it means trading cup cakes for science, then that is what a teacher has to do. This teacher with 23 children was able to provide those children with 23 additional learning experiences they have never had before and those experiences were unforgettable.

Plus, the Birthday Boy/Girl got to do all the really awesome stuff! And there were still cup cakes!

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 »

In our continuing quest to find interesting blogs and bloggers, we ran into Leah Simmers Photography Blog, where she was capturing her experience with Mentos and Diet Coke. Thanks to Leah for letting us share some her unique geyser pictures here. Check out Leah’s full blog post here. And yes, that is the Geyser Tube she’s using to launch that screaming geyser.

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.

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?

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?

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.
