Excellent
Information
Presentation
 information is flawless
 explanation demonstrates
understanding of how the
message moves along a
neuron, including protein
channels
 connects the ion
movement to the voltage
changes
5
 visual is clear and large
enough for the entire
class to see
 visual reinforces body of
the presentation
 presenter is professional
 presenter does not refer
back to notes during
presentation
 able to answer all
questions from the
audience
 attentive/respectful during
others presentations
