Learn about Coffee Science at Beals Science


At Beals Science, we love coffee! So much so that we've developed an entire set of lessons to teach people about the science and chemistry of roasting coffee, including information on how to roast your own coffee at home. Why do we care about the science of coffee? We've found many scientific concepts can be taught through coffee and coffee roasting. It is our way of combining science with something millions of people love.


Here you will find free lesson plans, free lab activities and an entire unit on "The Chemistry of Coffee developed by Chemistry teachers. More activites are being added to our "Coffee Science" page all the time so check back often or join our mailing list (see bottom of this page) to be notified as soon as the newest experiments and lessons are posted!


The Chemistry of Coffee

The Chemistry of Coffee was developed by Chemistry teachers at Billings Senior High School as an activity-based unit where students learn the process of roasting coffee beans, brewing coffee and tasting coffee. Along the way, they learn Chemistry topics including pH, Acids and Bases, Solutions and Dilutions, Experimental Design and so much more!

Feel free to use all or part of The Chemistry of Coffee in your classroom, with your science club or at home! And, for those who are involved with AP Chemistry, this is the perfect activity for after the AP Chemistry Exam.
