This site seems like it is for high school students but I found it after my interest was piqued by a book shown to me by a grade two student. In this book there was the periodic table as we all remember. However, on the next page was the periodic table with pictures of each of the elements in their raw form. This site expands on that idea by giving short videos that describe the elements and some of their properties and uses. The ‘molecules’ section also has some intriguing videos. Check out a cheeseburger in hydrochloric acid. Awesomely gross.
