Introduction to the course

This unit on Chemistry is chocked full of demonstrations and experiments for two big reasons. First, they’re fun. But more importantly, the reason we do experiments in chemistry is to hone your observational skills. Chemistry experiments really speak for themselves, much better than I can ever put into words or show you on a video. And I’m going to hit you with a lot of these chemistry demonstrations to help you develop your observing techniques.



In most standard chemistry lessons, a teacher walks in and says, “Now I will demonstrate the insolubility of barium sulfate by mixing equal volumes of zero point one molar barium chloride and zero point one molar sodium sulfate and observe what happens.” Anyone still awake?


In this unit, you’ll be mixing up things that bubble, ooze, slither, spit, change color, crystallize, and fizz. (I think there’s even one that belches.) And rather than announcing things in a dull and boring fashion, I’m just going to outline the steps and ask YOU to notice any and all changes, no matter how strange or weird. Or small. Even a tiny temperature difference can indicate something big is about to happen.

    That’s great idea – I did this for Physics but just realized it isn’t done for Chemistry. Let me look into it when I get back into content creating in a couple of weeks.

    Is there a link where we can easily print out the Table of Contents of the lessons for the Advance Chemistry course? I’m trying to save time by not having to make snippets of each page and copying before printing. Thanks!

Have a question?
