I myself have yet to teach a class during this pandemic. However this semester as I am in the mids of finishing my student developing year, I have learned that eventhough we are meeting virutally, it is still possible to make a lesson engaging. This is also including science experiments, it all depends on how you present the information and instruction to students. No matter if its through a pre-recorded lesson it is possible to be engaging and spread enthusiasm through the screen.
This semester I had a professor that had pre-recorded lessons and science experiments that we would interact with. We would have to create a claim, resoning and explanation in relation to the experiment and it was super interactive and engaging and learned alot from the videos. One must just take the chance of gettinng out of our comfort zone and be creative as much as possible (get in tune to our innerchild).
