Elements.wlonk.com is the home to The Periodic Table of Elements, in Pictures and Words. It is an interactive site where students can click on elements to see how it used and in what commons prodcuts it is found. For example, if you click on calcium an image of seashell appears along with a list of other places it is found.
In addition to the interactive page, you can also print out a copies or purchase a high quality poster.
This is something that I would use in both my middle and high school classrooms. Students often think they know what things are made of, but it would be eye opening for them to see what elements are really in the items they use every day. Connections like these provide a better understanding and enhance learning.
