Now that your students know what the elements are, how can we show them what they’re actually used for?
I’m glad you asked. On the site “The Periodic Table of the Elements, in Pictures and Words“, Keith Enevoldsen has made a very simple interactive periodic table that shows what the elements are good for. If you’ve got a few minutes in class someday, I’d recommend letting your students check it out. If you’re interested in other things periodic and orbital related, his main site is good for that, too.
(Thanks to Mental Floss for posting this site and bringing it to my attention. If you haven’t seen them, check it out.)
