Oreo Cookie Chemistry

I recently did a small but fun lab with my Honors Chemistry class. To learn about Limiting Reagents, students performed calculations on Oreo cookies divided into wafers and filling. This helped students visualize excess and limiting reactants, and why these must be determined when predicting products. The simple and fun experiment had a delicious conclusion when the students got to bite into their cookies – but with fresh, new Oreos, of course!
