This video is meant as a supplement to the lab of the same name, available in my store.
One of the coolest things about teaching physical science or chemistry is the fun labs that you get to do. The least cool things about chemistry labs is dealing with the make-ups, as labs involving chemicals can often be very difficult to "keep" for later, and close student supervision is necessary.
To alleviate these problems, I have created (for most of my labs) make-up videos. Now, students who miss labs can make them up while they're at home, and parents can also see what we're doing in class.
Another way this video can supplement the lab, is for teacher prep. A teacher can use this video to see how the lab is done, and what the results/conclusions should be.
The video is 6:30 long, and is in 1080p, mp4 format.
