3. Consensus/Conclusions/New Terms here here

4. Here are the objectives (unit 3):

5. a. Identify bulb filaments as parts of circuits that resist charge flow.

6. b. Use bulb brightness and compass deflection as indicators of flow rate.

7. c. Distinguish flow rate (amount/sec through) from speed (distance/sec traveled).

8. d. Use representations tools to show flow rate and bulb brightness on circuit diagrams.

9. e. Explain how adding series/parallel bulbs will raise/lower “overall” resistance.

10. f. Describe evidence that connecting wires have much less resistance than bulbs.

15. C3 Activity 3 (no file...in class demo) ... here is the description: Mark two lines on the floor with masking tape, and select eight students for each of two groups. One group stands side-by-side immediately behind one line as illustrated in Figure A. The other half lines up one-after-another behind the other line as illustrated in Figure B. The teacher will count time out loud. Each group must be prepared to move as instructed because they will have only 1 second in which to move. (Count a rapid “1-2-3-4-5” or “One-thousand-one” for the 1 second count.) or you may assign two students the job of timer: the 1st timer for the side-by-side group, the 2nd for the single file group
