I’ve been making major updates and changes to my materials in the intro physics course this year. It is the first year we are teaching a yearlong physics class to everyone (10th graders) in my school as the result of a big curriculum redesign in science, and the first time back to teaching a course like this in a few years for me. I will try to update this blog with each of the new activities and changes as I have time. First up: the kinematics stacks of curves.

The outer layer of the sun is slowing down, something we’ve known for decades but haven’t been able to figure out until now. Continue reading
This useful video provides practical advice on the safe use of a Van De Graaf generator.
The following article provides the results of a literature search of radon and its hazards of particular interest to high school science teachers. The article was written by Dave Gervais, chair of STAO’s Safety Committee. Continue reading
From the Institute of Physics and the National STEM Learning Centre and Network (https://www.stem.org.uk/), this video is aimed at teachers and shows how to get the best out of a Van de Graaff generator. In the video, Michael de Podesta explains how the generator works and gives some tips on getting consistently good results when using the apparatus. The video concludes with a simple but effective demonstration of charge.
Making liquid nitrogen is hard – in fact up until 150 years ago scientists doubted whether it was even possible to liquefy nitrogen. In 1823, At the royal institution in London, Michael Faraday first produced liquid chlorine, kind of accidentally by putting it under high pressure. He similarly liquefied ammonia. Continue reading

Back to school in a BIG way
First, astronomers made history when they detected a gravitational wave from two black holes merging. Then it was two neutron stars. Now, astronomers believe they’ve detected a gravitational wave coming from another first-time discovery: a black hole swallowing a neutron star.
