This is a great lab with low error and clear instructions that your students will enjoy. The lab includes an introduction to how baking soda works in recipes where the heat of the oven or skillet causes decomposition of the bicarbonate into carbon dioxide gas, acting as a leavening agent. The lab takes 50 minutes start to finish including calculations, so you can actually finish it in a class period!
The file includes teacher instructions and set up, safety precautions, and a key. All you need is basic chemistry equipment and a box of baking soda. It also includes student data tables for lab books if you use them.
