Microscopy 20 Questions

In this microscopy investigation students play a game of 20 questions to develop their skills of questioning, observing, and listening. The instructor can either project the microscopy images (below) or make handouts of them and have students ask yes or no questions. The students can ask up to 20 questions or make guesses to try and figure out what the images display. Instructors can also make their own using a digital microscope such as the Digital Blue QX5. The microscope works great for making 20 questions slides for warm-ups or for classroom experimentation.
