The first blog post of this seawater-oceanic shipping series deals with an introductory classroom activity that challenges students to predict how the composition and temperature of seawater influences a ship's buoyancy.

Bill Hammack- never heard of him, right? I love his videos as he dissects the physics and chemistry of how things work. Nothing fancy or gimmicky. Just good ol' experimentation, acute observation, rational deduction, and contagious curiosity.  

The June, 2018 issue of the Journal of Chemical Education contains an article tha

In the January, 2018 issue of the Journal of Chemical Education, Jeffrey Statler describes several experiments that can be conducted with liquid air.¹ He demonstrates that liquid air can be easily collected by simply immersing a test tube in liquid nitrogen, which has a

It looks as though I’ve discovered that density bottles can be used to explore differences between heterogeneous and homogeneous mixtures!

     Augmented reality is a type of technology that uses an app to turn a hidden QR code into a three dimensional object on a screen as viewed by your camera. I have heard that there are biology related augmented reality pictures.

I recently posted a video on Twitter of an experiment my students were conducting in class. I thought I’d blog about the experiment, since it seemed to generate a lot of interest.

If you are familiar with Modeling Instruction in physics, you know there are awesome assessments at the end of units called practicums. First, let me distinguish between practicals and practicums. The purpose of a lab practical typically is to assess a student’s ability to collect and analyze data.
