Sample Discussion Prompts
-
Caleb asks, “Is there a rule, that like dictates which way the charge is going to go?” Are they looking for a guiding principle or avoiding trying to make sense of the situation? Something else?
-
Do you think Caleb is joking when he first says that the cloth “looks like it can hold electrons” (line 15)? Why or why not?
-
Caleb’s remark that the cloth “looks like it can hold electrons” turns into a joke. Is this productive for the group, or does it push them off-task?
-
Do you think that the students’ idea that electrons “stick” or “slide off” is a useful one? How does it compare to an expert explanation?
-
What student ideas about electronegativity are indicated in this episode?
