Density differences cause objects to “float” in liquids that are already stacked on top of each other. With this science-magic trick, you’ll put a new spin on our famous Density Column demonstration. First, you’ll discover how to stack nine layers of liquids on top of each other. That alone looks really cool, but then you … Continue reading
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 … Continue reading
This lesson is used for students to analyse the design of a technological device that protects other devices by using or controlling static electricity (such as paint sprayers, photocopiers, lightning rods or grounding wires). I use this lesson near the beginning of the electricity unit in SNC1D1, after introducing static electricity and charging by friction, … Continue reading
Black Holes are known for consuming everything that falls into them, but is there a point where these galactic devourers can’t stomach anymore?
How the brain works, how we learn, and why we sometimes make stupid mistakes.
November 10, 2019 is World Science Day for Peace and Development, and November 9 – 14, 2019 is the International Week of Science and Peace. In today’s world, it is more important than ever to show students how everything we do is linked and how we all have in impact on the world around us. … Continue reading
