Bombardment of Information: are we overstimulating our children?

The other day we went to the Zoo with my boys (a five year old and a three year old). In the car, we were talking about which animals the kids would really like to see, and what animals would be there, etc. I was pumped because the kids love animals and showing them an elephant in a book and in real life doesn’t compare. In a book, there’s no movement, no comparison in size with the surroundings, no texture. My five year old son was especially excited, and he had a million questions for me about the zoo and the animals: “How do the giraffes drink water when they’re so tall? Do giraffes have a red tongue or a black one, like daddy says?” etc.

Competition – Is it a good tool to motivate kids?

I always thought that competition is an excellent way to motivate kids. Many times, I made contests in the class, competitions, etc. I always found it that extra bit more fun when I was a student, if I had to compete against some other students. That’s probably why I really like games. My friends always tell me that I am very competitive and some friends even tell me that I’m overly competitive. It’s true. I make a game out of everything. Even with myself. With anything I do, I try to improve myself, get faster, get more efficient… win.

Just like my life, I run my classes as a place to improve, a place to get faster, to understand best, to get more efficient – and what better way than a friendly competition?!

Understanding Projectile Motion Misconceptions

I am reading an awesome book on Cognitive Sciences and how it applies to teaching students in the classroom: Schools for Thought – a Science of Learning in the Classroom by John Bruer. I will write more on this book later, but I wanted to focus on an idea I got from it to teach in the classroom. One chapter of the book relates to teaching science, and specifically, teaching Newtonian Physics… exactly what I’m teaching right now to my grade 11 physics class.

The Pendulum Experiment

This lab is designed to investigate the motion of a pendulum, specifically its period. From some initial observations, the students are to collect reasonable data to determine the acceleration due to gravity.

Note: You will need a pendulum setup: a light string connected to a heavy weight on one side and a stationary object high above the floor on the other (like the ceiling), letting the pendulum swing back and forth. The string length should be adjustable.
