Vegetarian? Vegan? Pescatarian? Flexitarian? Macrobiotic? Lacto-ovo-vegetarian? AHHH!?

Today while working in Mrs. Holyoke Walsh's classroom during noon hour, I overheard someone ask Mr. Buntain if he was a veggie. Well of course that was quite funny, because clearly he's certainly not a vegetable. Naturally, she was not asking in the literal sense, but rather if he was a vegetarian or not (Incase you're wondering, he isn't). I've always been sort of curious about vegetarianism and what it actually means. I guess I know that it means you don't eat meat, but after doing some research, I found out that each vegetarian has their own personal motives for choosing this diet and what they eliminate. As for why people decide to become "veggie", there are lots of different reasons. One website I found suggests that humans were not biologically developed to be carnivores, but the video I have posted below suggests the opposite. Vegetarianism has also been associated with "hippies" I guess you could call them. Did they start it? Who knows. Lately, it's becoming a fad. Just as going green by recycling, using those cloth bags sold by pretty much every grocery store and eliminating your carbon emissions have become very popular in the last few years, people are deciding to "go green" on the inside as well. It's relatively healthy, as long as you make sure you're getting all the necessary vitamins and protein from other sources. Our great friends at
What You Ought To Know have provided us with a another nice video to clarify some of these things, including what the terms in the title of this post mean. Also, for more info check out The Healthy Vegetarian.

Teenager's Sleep Patterns Are Different Than Those of Adults and Children


It's well known that during period one, no one is awake yet and during period five, everyone is trying their hardest to resist their drooping eyelids because we stayed up way too late working on some take home test or guided reading for Biology. Just kidding, we love those so much...

Here's the reason why: The presence of the sleep-promoting hormone melatonin is present at different times of the day. In teenagers, it rises later at night and drops a lot later in the morning than in an adult or a child. A team of researchers at E.P. Bradley Hospital in Rhode Island, USA took saliva samples from teens to try and prove this theory, and they did just that. Some schools in the US are even pushing their morning bell to a later hour, so that the students are more alert and able to focus. They say this changes at about age twenty. Here's the full article that was featured in the Washington Post.

Thinking of Bungee Jumping?

Nicole and I were talking about things that create adrenaline rushes and things we'd like to try someday. We came upon the topic of bungee jumping. I said I probably wouldn't try just because of all the strange things that can happen. Here is just one, that I know of because of a friend's personal experience. She went bungee jumping about two years ago (the date on the photo is wrong, this was actually in 2006) and got this strange hemorrhage on her eye. The blood vessels in her eye burst because of all the strange forces caused by the jump that don't normally exist in nature. There was slight vision loss for about a week and it was a little painful at first. It also didn't look too pretty for about a month. I was kind of curious about what kind of damage was done, so I did a little research. There was no extreme premanant damage, which is good. I have included pictures of her husband's jump because the photo was better and her eye afterwards, with her permission of course. Check out this link to see a little more about macular hemorrhages from bungee jumping.

What the heck?
If each and every one of us lived like the average North Amercian, eventually we'd need five planets to sustain us. Crazy, eh? WWF has developed a campaign and a ten principle plan to help cut down on the harm we're doing to our planet. Reducing your carbon footprint in simple and effective ways is the easiest way to help bring this number down. Take a look at the video below for a bit more info and then head over to this site to calculate your carbon footprint and find out some fun and easy ways that you can do your part!

Here's a cool site called 'The Wild Classroom' that has a lot of videos and articles about anything Biology related. Most of it is about the environment and biodiversity. It's run by a team of biologists who call themselves the "EcoGeeks". They travel around the world shooting videos on different specific topics. If you're into podcasts, you can subscribe to theirs on the site as well.
