The Periodic Table of Videos has been around for a while, but they are actively updating videos and creating new ones. The videos were created by Brady Haran at the University of Nottingham. They are short and very informative. I like to use them during lessons when my classes are discussing specific elements. For instance, some of us like to demonstrate adding lithium and/or sodium to water (always show this in a hood with a safety shield in place). But, it is too dangerous to add potassium to water in my classroom. I can show the reactivity of all of these elements using the videos at Periodic Table of Videos Web site. Today, we had about six minutes to spare after a unit test. I took the opportunity to show one of the videos. I allowed the students to pick the element. They were engaged and walked out of the classroom talking about chemistry. It doesn't get better than that!
They also have a new series called Molecular Videos that I am looking forward to watching. These feature molecules and compounds.
