Note: Below the instruction manual, there is a video that serves as a good resource and includes useful background information. Below the useful background information, a supplemental video to make observations is found. This video is only to be used as a last resource, in case experiment 2 does not work in the lab due to humid conditions.
This video is meant to be used to record observations if and only if the humidity in the lab prevents the Braun electroscope to deflect the needle in any significant way.
