In this video, Dr. Wargo demonstrates how to implement a classical electricity Quick Quiz. Here, an illuminated bulb has an ammeter placed across it. What happens? Use this video to learn how to implement the Quick Quiz and authentically engage your students in dialogue.

Quick Quizzes (QQs) are carefully designed problems that allow teachers to easily engage their students in authentic discourse about natural phenomena. To minimize barriers to entry, we focus on systems that require minimal prep time and use mostly readily available materials. This is one video of many across the high school physics curriculum that aims to prepare teachers to engage their students authentically. QQs are one tool of many that the Idealized Science Institute recommends.
