Stained Glass Candy Lab
This inexpensive lab activity is a fun application of mole and molecule calculations for chemistry students. This two day activity has students calculating mass, moles, molecules, and formula weights while following specific instructions for making a semi-hard peppermint flavored candy in jewel tones. It’s a great activity for the holidays, Valentine’s Day or even St. Patrick’s Day.
Careful measurements and following the instructions well = great product; sloppy = crumbly mess, or worse – burnt sugar.
Note: Cooking is done in aluminum muffin or cupcake cups cut from a disposable pan. Cooking can be done with Bunsen burners or hot plates. You do not need food safe thermometers because you’ll use the qualitative, soft ball stage as a measure for temperature.
