Resistance
Overview
This lesson uses data that the teacher collected at INDI to help students understand resistance in an ICP class.
Learning Objective
ICP.6.4 Define and describe the relationships among voltage, current resistance and power in open and closed electrical circuits.
Procedure
Engage:
1. BBC youtube (about 1 min): https://www.youtube.com/watch?v=5Qh-4Wm51pw
Study:
Notes: 2. Define resistance (what does resist mean?)
- Students give examples of good conductors and insulators.
- Which have more resistance?
3. Teacher: describe experiment w/ graphene at IUPUI
- Draw diagram and Students try to predict what will happen with the resistance with the presence of gas
- show data that measures resistance
Activate:
4. Students can explain to each other why the resistance changes with the presence of gas.
