Teaching labs will involve many of the challenges that all classes will experience. As a good place to start, please consult Best Practices for All Fall Courses, High-Touch Practices for Teaching, and Equity for Remote Students. As with all classes this fall, scientific lab courses should "design for online" given that some students will likely be remote at some point during the semester. Start with your learning objectives and build from there with fresh eyes. Resist doing what you have always done just because you have always done it.
In-person labs will also have their own challenges due to smaller spaces and the potential reliance on expensive shared equipment and group transportation.
There is no single solution and each faculty member will need to design their lab experience to best meet the learning objectives of the course given the situation.
