Make your own molecules!

 I use molecules for both Chemistry and Biology.  Since I teach these courses regularly, I bought molecular model sets.  There are loads of ways to make your own molecules: DIY Clay model kits, straw models, beads and pipe cleaners (see examples here), and paper models.  Instructables has these plans for making an excellent, organic model kit.  Here is yet another worksheet.  Use your kit to build these molecules as the kids learn how to name molecular structures.  Here is the slideshow I prepared to introduce Organic Nomenclature.  Hope this helps!
