Transmission of NERVE IMPULSE

This lesson plan is for higher secondary biology - 11th std. The lesson plan revolves around - Action and Resting potential, terms - polarized, depolarized and re-polarized. with respect to Neuron and transmission of nerve impulse along a non-myelinated neuron. I would really like reviews on this lesson plan as I am a student pursuing MA in education and would love to learn and improve through the suggestions that I could get from this platform. 

Looking forward for reviews and suggestions.
