News — high school physics

We have all been there. You introduce the concept of momentum, write p = mv on the board, and your students nod along. It seems simple enough—mass times velocity. But then you introduce impulse, the impulse-momentum theorem (FΔt = Δp), and conservation of momentum. Suddenly, the nods turn into blank stares. Students start confusing momentum with energy, or they struggle to understand why a bouncing ball experiences a greater change in momentum than a ball that sticks to the floor. Teaching momentum in high school physics can be a challenge because it requires students to connect abstract mathematical formulas to...

You're standing at the front of the room, explaining the difference between velocity and acceleration. You've drawn the graphs, you've written the equations, and you've even walked across the room to demonstrate. But when you look out at your students, you see it: the glazed-over eyes. The subtle panic. The realization that they are completely lost. Teaching kinematics is often the first major hurdle in a high school physics course. It's the unit where students realize that physics isn't just about memorizing facts—it's about applying math to the real world. And for many students, that transition is terrifying. They confuse...

If you've ever taught high school physics, you know the moment. You've just finished explaining Newton's First Law, and a student raises their hand to ask, "But if an object in motion stays in motion, why does my skateboard stop when I stop pushing it?" It's a classic question that reveals one of the most persistent misconceptions in physics: the idea that force is required to maintain motion. Teaching Newton's Laws of Motion is often the first time students are asked to fundamentally rewire how they perceive the physical world. They come into your classroom with years of intuitive, Aristotelian...

If you've been teaching physics for more than a few years, you've probably felt the shift. The days of handing out a worksheet with 20 identical kinematics problems and calling it a day are fading. Instead, administrators and curriculum directors are tossing around acronyms like "NGSS," "Three-Dimensional Learning," and "Phenomena-Based Instruction." For many physics teachers, this transition feels overwhelming. You already have a curriculum that works—why change it? The truth is, the Next Generation Science Standards (NGSS) aren't about throwing away your favorite labs or abandoning Newton's Laws. They are about shifting the focus from what students know to how...
