Does Oil Make Ball Bearings Rotate More?

In the final part of our series on ball bearings, we ask how oil affects the rotation of a thrust bearing? This is part five of a series on how to conduct a long-term authentic research project. Here we use this long-form lesson to show how problems inevitably pop-up and are mitigated. We hope that it will inspire both teachers and students to begin their own long-terms!

What are Quick Quizzes?
====================
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.
