This screencast is about the amplitude of the global potential and how it’s affected by the intensity of stimulations applied to the nerve. This is a topic that’s thoroughly discussed in grades 10 and 12 of the Biology Lebanese curriculum and I have already posted about my simulator, the one I use in my classroom to explain the aforementioned concept.
In this video, I put the simulator into good use and demonstrate how it can be used as a valuable tool to explore the concept in an interactive way (feel free to contact me if you need an exploration sheet for a guided discovery approach using this simulator).
