We all know that even after we teach the students how to do something, they will still ask us what to do immediately after starting an activity. Use these quick guides with your students when they are learning how to use a microscope, or might need a quick review. One side of the card has steps for the students to follow as they try to focus their slide. The other side of the card has some common troubleshooting tips and a diagram of a microscope. These cards help the students be more confident and independent with the great side effect of less broken microscopes!
