If life hands you lemons, make lemonade. This age-old advice is hard to argue with, but if you’re handed lemons in science class, it’s time to make observations. “A Lemon of a Lesson” provides valuable opportunities for students to hone their observation skills and extend these observations through the use of magnifiers and measuring devices. Once this seed of “observation awareness” has been planted, students understand why they need to make more in-depth observations—and do so—during later inquiry experiences in class.
