On Friday, I was so pleased to be able to return to one of my favorite days of the year, High-Interest Day at Brookfield Elementary School. This is a day where I have been able to bring the concepts of physics to k-5 graders. You may be asking yourself, "Elementary students doing physics?" YES! Not just experimenting, but understanding the concepts behind the physics of electricity and sound. This is a very special day I have had the opportunity to be involved in since 2017. So, how are we able to bring the concepts of electricity and sound traditionally taught to high school 11th and 12th graders to the elementary level? There are a few keys 1) make it a hands-on experience 2) remove the mathematical calculations and make it practical. In the past, I had the luck of bringing a handful of my physics students with me to guide the elementary students through the concepts that they had learned over the course of the year. But in my new role as a Teaching and Learning Speciali
As I look back on the material we covered in physics this year, I can’t help but see the connections to my life as a professional. I’ve spoken about Newton’s 1st Law of Motion in my last post . But, the 2nd Law is equally relevant. It’s great to be in motion. But constant motion in the same direction at the same speed, isn’t always a good idea. What if you need to get somewhere faster, make a turn, or come to a stop. In those cases, it is essential that you are able to change your motion. The physics term for change in motion (how fast or what direction) is acceleration. More specifically, acceleration is the rate at which your motion is changing. So, acceleration is a function of time. The only way to change an object’s motion, or get it to accelerate, is with a push or pull. In other words, an acceleration requires a force. To be more accurate, an unbalanced (or net) force. Newton’s Second Law of Motion describe the factors that affect this acceleration: The net for
