Tomorrow is the last day of school before a two week vacation. I am completely fried. I picked up an "overtime" load for the last month, and exams are coming. So much work!

I really like onlike puzzles. A recent one that I found and really enjoyed was a Toyota IQ challenge. Kind of funny that Toyota created a puzzle, but it has nothing to do with Toyota; the puzzle is actually quite simple and fun. Try to unlock the cube!

Today in Montreal, schools are closed for the second snow day this month. This is one of those perks I quite enjoy as a teacher. It's unexpected (like a surprise birthday party), and for most adults, it's a great hassel. However, we get an extra day off of work - paid.

I never liked PowePoint presentations, therefore I never use them as a tool in the classroom. The problem is, that I have never seen a GOOD PowerPoint presentation.

However, I think now, after seeing this: "Presenting about presenting" by Scott Elias, I understand how the PowerPoint is a pretty good presentation tool.

If you ever plan to present or teach with PowerPoint, this "Presentation on presenting" is worth a look.

I am finally teaching what I love: Physics.

In the last few years, I have been travelling from city to city, from province to province, from school to school. (following my husband's job, taking time off for kids, etc.). So anytime I get a job at a school, I only get the remains, the things "they" couldn't find anybody else to teach. Thankfully, math and science teachers are in great demand, and I never had a hard time finding a job. But the problem remained that I was not teaching my favorite subjects. Finally however, by a stroke of luck, I am now officially teaching physics.

Today, I'm proud to be a science teacher in Canada. Our students ranked thrid in the world for 15 year olds (the exact age group I teach) in Science on an international survey (57 countries and 400 000 students surveyed). That's pretty impressive. Check out the in depth results here.

For about a year now, I've been reading an awesome blog called Passion for Puzzles. Everyday there is short new entry with news on something "puzzle related" along with a picture. Whether it's a flash puzzle, a new word or math puzzle, an "Escape the Room" puzzle, a new jigsaw puzzle or even puzzle furniture, the author is there to report it in a short concise manner, with an appropriate link.

With the internet being so big, I find it hard to find new interesting puzzles. Therefore, for puzzles, Passion for Puzzles is the place for me!

I have long been a fan of really elegant proofs. One of the best is Euclid's answer to the question: How many prime numbers are there?

For the non scientists out there, the alkali metals (the first group of the periodic table) are very very reactive. They don't occur in their elemental form in nature, because they react so rapidly with water or even air (oxygen). But, because I am teaching chemistry, the periodic nature of reactivity, and similar chemical properties of families, we (along with another crazy teacher in my science department) have decided to order lithium, sodium, and potassium for a demonstration of the high reactivity of alkali metals.
