Did you figure out how the experiment in Chemical Mystery #14 was performed? The solution is presented here!
You are likely aware that diamonds are converted - albeit slowly - to graphite under normal conditions. Thus, diamonds don't last forever, in contrast to the popular advertising slogan. However, did you know that you can use chemistry to prove that diamonds are not forever? It's simpler than you think...
Simple methods to prepare liquid air are described. In addition, ways to test the properties of liquid air and other liquefied gases are explored.
Now that the 2018 administration of the AP Chemistry Exam is in the books, all of us AP Chemistry teachers now have an opportunity to reflect on the year as we turn our attention toward preparing for the fall.
If you want to lose weight, you have to burn calories. Anyone who has gone on a diet knows this. But when someone loses weight, have you ever wondered where the lost mass goes?
Have you been watching the Winter Olympics? I have been able to draw many similarities and relevance to what I am teaching in the classroom. How about you?
