At 8 p.m. on March 29, the world will turn off its lights for just one hour – Earth Hour.
Some of you may already know about Earth Hour, I know I didn’t until my daughters told me about it. The idea started last year, with World Wildlife Fund in Australia pioneering the first Earth Hour. Almost 2.3 million Sydney residents participated‚ including more than 2,100 businesses. Just one short hour resulted in a 10% reduction on the electrical grid, saving 25,000 tonnes of carbon dioxide, the equivalent of taking about 50,000 cars off the road for an hour. This year the effort is global, with six continents and as many as 20 cities participating. By all of us doing a little bit we can show that it IS possible to take action on climate change.
We are going to participate in my house because climate change is the biggest environmental threat to our planet and one of the main concerns for my family. We are already seeing its impact. Participating in Earth Hour is a simple way to show that we want to be a part of the solution and it sends a powerful message to others that, together, we can make a difference. We will do our part earlier than March 29th as I will be away at the National Science Teachers Association Conference in Boston on that date. Maybe I’ll be pleasantly surprised by organized Earth Hour activities going on in Boston on the 29th.
Turning the lights off for one hour seems like such a small thing, but the campaign is also about awareness. I am telling all my friends and family about Earth Hour with the hope that some of them will get involved and participate and learn more about the impact we have on the earth every day.
To register yourself and your family or for more information go to the WWF Earth Hour page.
It doesn’t have to end at 9pm on March 29th. To help support our continued efforts, WWF-Canada has created The Good Life‚ a fun and interactive online community for concerned Canadians who want to stop talking about climate change and start taking action. Registrants on the site can access tips, information, and even track their personal reduction in carbon dioxide over the long term. For more information on what you can do after Earth Hour, visit www.thegoodlife.wwf.ca.
Switching off your lights for one hour is just one simple action that you can take to help make a difference; the global darkness will send a powerful message that we care about our planet. Why not make it a monthly, or weekly, event in your house?

If you teach science this conference is a must. We have been exhibiting at the National Science Teachers Association national conference for many, many years and we always learn something new, from the teachers who visit our booth to other exhibitors and, when we have time, from session presenters.
Our favorite presenter of all time is Nancy Harrison (and not just because she recommends The Digital Frog 2.5). Nancy is a practicing pathologist who loves animals and firmly believes that cutting up dead animals in high school is of little pedagogical value and countless animals die unnecessarily.
Nancy’s love of animals led her to research all the computer-based alternatives on the market. Recognizing that teachers are pressed for time, she felt this would help them make the switch from cutting up dead animals to a computer-based alternative. Initially, Nancy showed the teachers several programs, but eventually honed her presentation to just two programs, which she deemed to be the “best of the best”.
Whenever we can, we attend Nancy’s presentation and listen as Nancy explains to a hushed audience how her high school science teacher influenced her life and her career. And, of course, we love it as she tells the audience why The Digital Frog isthe best of the best. We are very fortunate that Nancy endorses our program (as did eSchool News readers) but we do NOT give her any financial support. In fact, Nancy will not even allow us to buy her a cup of coffee.
Nancy’s presentation at CSTA in Long Beach last year was full to overflowing. This year NSTA is in Boston and Nancy will be presenting “Virtual Dissection: The Best of the Best” on Friday Mar. 28 from 12:30 to 1:30 in the Amphitheater of the Seaport World Trade Center (so you might actually get a seat).
By the way, our booth number is 1337 and we will be holding a draw for an unlimited Building Site License for The Digital Frog 2.5 (list price $899). Stop by our booth, mention the “secret” password – The Year of The Frog – and triple your chances of winning.

I may be known as the frog lady these days, but there was a time when I could not tell a frog call from a bird call. That all changed when I became involved in Digital Frog International. The biodiversity section of The Digital Frog 2.5 features frogs and toads of North and South America, together with sound recordings of their calls.
Way back in 1995, we gave the first version of The Digital Frog to our vet to review. She reported back that her two year old son spent hours and hours clicking on the frogs and listening to their calls.
A few years ago we donated software to the Toronto Zoo and I spent a day in their conservation area helping visitors navigate our software. The frog calls were extremely popular.
I have also used this section to help children identify the spring peepers, northern leopard frogs, green frogs, wood frogs and tree frogs that can be found on our country property. Last summer my grandchildren were fascinated as they watched a grey tree frog, quickly nicknamed “Norman”, change from grey to green as he emerged from his hiding place. From then on, whenever they heard a tree frog call, they all rushed out looking for Norman.
Of course, I still secretly believe that the herpetologist who provided the recordings we used in the program was playing a joke on us —the bullfrog sounds just like a cow!
To learn more about the frog calls and other information on the frogs and toads of North and South America available in The Digital Frog 2.5, read more about the program’s ecology section. Or preview it for yourself with a free demo of The Digital Frog 2.5.

As part of the Year of the Frog, the Vancouver Aquarium has produced “Bullfrog Ballet”, a two-minute, high-speed video showing bullfrogs feeding on insects in slow motion, giving them a grace you might not normally associate with large (and seemingly ungainly) bullfrogs.
From the Vancouver Aquarium’s description:
Bullfrogs (Rana catesbeiana) are native to eastern North America, from Canada as far south as Florida, but they’re invading British Columbia, where the Vancouver Aquarium is located. They were introduced here in the early 1900s by people wanting to farm them for their legs.
As you can see, they’ll eat just about anything that will fit into their mouth. They can easily tip the delicate balance of nature in places where they are not naturally found.
Ironically this widely introduced species is disappearing in Ontario, Canada — part of its natural range.
The video is part of a wider exhibit running at the aquarium, “Frogs Forever?”, to raise awareness of the dangers facing the world’s frog populations and what we can do to help.
