I hope you’re all enjoying your summer vacation. Maybe you’ve got some plans for the Independence Day weekend. Then again, with gas prices shooting into the stratosphere, maybe you don’t.

In these days of pricey petrol, you’ve got to get a little creative to save money on gas. That’s why you should head over to SmartPlanet and read their post, Top 10 eco driving tips to beat fuel rises. These tips include common sense (car pooling), hypermiling (get into second and fourth gear quickly), and some tips that are actually more convenient than conventional wisdom (at high speeds, crank the A/C and keep those windows rolled up to reduce drag).

The list is packed with useful advice and charming Britishisms like motorway, lift, and complaints about how “unleaded’s now 112.6 pence per litre,” whatever that means. So don’t let high fuel prices keep you cooped up this holiday. Read this advice and hit the road! -BILL FERRIS

If you or your students ever take a walk in the woods on a field trip, it’s a good idea to know the potential dangers. I’m not just talking about bears, either. You can find a lot of plants that can harm humans through ingestion, or even by simple touch.

Before heading into the wild, arm yourself by reading this list of the 20 Deadliest Plants on the Planet. You’ll find the usual suspects like hemlock and deadly nightshade [editor's note: that's a really cool name for a plant], some wolves in sheep’s clothing like the angel’s trumpet, plus a couple surprises – I knew poison ivy makes you itchy, but I had no idea if you burned it, the smoke can kill you if you breathe it in. Don’t miss the doll’s eyes plant, which looks a lot like what it sounds like. The berries are chock full of cardiogenic toxins which can give you a heart attack, but the fact that the berries look like eyeballs will probably be enough to dissuade even the most curious (or hungry) eaters. -BILL FERRIS

The only specific memory I have of a field trip I took as a student was an elementary school trip to the local planetarium. Why? Because it was the first time I experienced astronaut ice cream. It tasted like regular ice cream…but…it was crunchy…??!! My mind was blown.

In retrospect, my teacher probably dreaded these trips at least a little bit – most of us students probably climbed back on the bus whirring with sugar buzzes. To reflect further, wouldn’t it be great it my most vivid school field trip memory wasn’t a fond reminiscence of something I’d encountered in a gift shop? Wouldn’t it be better if my mind had been blown by something that had actually happened inside the planetarium? Like, say, the notion of our lonely little planet spinning at the edge of the Milky Way galaxy, perhaps one galaxy of millions in the universe? Shouldn’t that be more intriguing than the idea that some guy in a food lab figured out how to dehydrate ice cream?

Your students deserve better than this. To help make sure you maximize the educational value of your trips outside the classroom walls, you’d be wise to read this Kidcast blog post about podcasting and field trips. The post offers eight excellent suggestions on how to use podcasting to engage your students in the learning process before, during, and after the field trip. Each one is a great application of podcasting that uses the technology to scaffold learning: having students create a quiz show about the field trip location, for example, or recording a public service announcement to advertise the site.

Many thanks to Kidcast for reminding us there’s more to field trip preparation than permission slips. -EMILY JACK

Kidcast 53 – Podcasting and Fieldtrips

Virtual Field Trips offers a bundle of web excursions – perfect if you want to break the ennui of concrete walls without actually having to go through the rigamarole of leaving school grounds. The trips are simply step-by-step web seminars designed to educate and fulfill the needs of taking an actual field trip without having to keep everyone in a single file line. There are several subject areas here to explore, including fine arts, science, foreign language, social studies and technology. Each subject has about thirty or so activities and lessons, complete with pictures and links to outside resources.

It’s no substitute for a real field trip, but if your class is tired of that trip to the farm where someone will inevitably lose a retainer or fall in the mud, you might stay indoors once in a while and get all the info from this site without any of the fuss. You can also suggest and create your own virtual field trip so that other teachers can benefit from your expertise. One of my favorite aspects of the site is that all of the lessons are consistent in design and flow, so there isn’t any need to re-program your brain to teach more than one of these lessons. The design isn’t the most aesthetically pleasing thing on the web, but hey, the content is great. –JEREMY S. GRIFFIN
