SCEN 102 - 3/23/00 Voltage and Current in a Simple series circuit - "Take 2"
Your instructor will set up the following circuit:
|-------------wire #1-----------------------|
Positive terminal |
Battery Light bulb
Negative terminal |
|-------------wire #2-----------------------|
Think about the three conceptions of electricity described by your instructor:
"Colliding Currents" model (incorrect conception)
"Used-up" model (incorrect conception)
"Circulating Currents" model (correct conception)
| Property | What you would see in the circulating currents, or correct, model | (ODD NUMBERED GROUPS MUST FILL THIS IN): What you would see in the colliding currents model | (EVEN NUMBERED GROUPS MUST FILL THIS IN): What you would see in the "used-up" model |
| Voltage drop across wire #1 | zero | ||
| Current in wire #1 (including direction) | towards lite bulb | ||
| Voltage drop across light bulb | 1.5 volts (whatever the battery is) | ||
| Voltage drop across wire #2 | zero | ||
| Current in Wire #2 (including direction) | same as current in wire 1, away from bulb | ||
| Anything else you would like me to measure |

SCEN 102 -- 3/16/00
Discuss the Big Electricity Problem.
In the view of your group, what do you think happened?
What more do you need to know about electricity in order to confirm your guess as to what happened?
Batteries and Bulbs Activity
When you did the "batteries and bulbs" activity, some groups probably got the bulb to light on the first try, some got it to light on several tries, and some could not get it to light. Please list, within your group, what happened:
Made the light bulb light on the first try _____
Made the bulb light after several tries ______
Were not able to make the bulb light _______

SCEN 102 - Group work in class 2/15/00
When I ask you to do work as an individual, put your answers on the WHITE COPY, which you may keep. When I ask you to do work as a group, put your answers on the COLORED SHEET, which you should turn in as a group assignment.
1. ConcepTest on speed-time and distance-time graphs. Whether you are taking this test as an individual or as a group, follow these instructions. Fold your answer card in four, and when I blow the whistle, hold up your card so that YOUR ANSWER shows towards the front.
1. What is the answer to question 1? _____
2. What is the answer to question 2? _____
3. What is the answer to question 3?______
4. What is the answer to question 4? _____
You may wish to keep notes on whether your answers to questions 1, 2, 3, and 4 are correct or not. Depending on how the class goes, I may ask additional questions.
2. Acceleration: Continuation of the Fossil Tracks problem
In words: At what times are the pink and blue creatures CHANGING THEIR VELOCITY or ACCELERATING?
In pictures (if we get here): Draw an acceleration versus time diagram for the pink and blue creatures.

SCEN 102 -Group Work in the Big Class Tuesday, February 10
1. Looking at just the left hand part of the graph, describe in words the motion of the two creatures.
2. Draw distance-time and speed-time graphs which describe the motion of the two creatures.
3. (We will only do this if we have time.) Look at the whole picture. Draw a distance-time and speed-time diagram for the creature which left the larger footprints. What do you think happened in this situation?

MINUTE PAPER NAME: ________
I will stop class two minutes before the scheduled ending time and ask you to fill out a half-sheet of paper describing your reactions to class at this point. You will earn five participation points for this paper; if you wish it to be anonymous, please put your name on one half-sheet and fill out an additional half-sheet, without your name, but with comments. Please answer the following questions:
Should the activity in class today be included in the course in future years? (Circle one)
Definitely Yes Probably Yes Maybe Probably Not Definitely Not
What is the most important thing you have learned in class so far?
As you leave class today, what is the biggest unanswered question in your mind?
While I will not always stop class as I did today, if you wish to react to what's going on in class at any time, please feel free to do so. Minute papers can be anonymous.

SCEN 102 -Group Work in the Big Class Tuesday, February 8
These energy chains should be drawn by the group, and everyone in the group should understand how they are drawn.
1. Draw an energy chain for the bouncing ball.
2. Draw an energy chain for the ball which doesn't bounce very well.
3. Based on your energy chains, which of the two balls - the one that bounces well or the one that doesn't bounce so well - will be hotter once you have dropped it?
