course Phy 201
5/23 1 am
You will participate during the semester in two series of collaborative lab activities.The first is designed to be relatively painless, and to begin to develop a degree of teamwork and collaboration.
These activities are designed for teams of four individuals, each with a specific function:
• The designer will come up with the idea for the activity and will specify for other team members how the activity is to be conducted.
• The experimenter will follow the designer's instructions to set up the experiment and collect data.
• The analyzer will analyze the data.
• The interpreter will describe what the results mean.
For each series of activities, you will participate in four different investigations, one as designer, another as experimenter, another as analyzer and another as interpreter.
As each investigation progresses, you will follow the work of your fellow team members.
Please summarize the above, as best you can, in your own words:
****
For each lab there will be four different job titles for each team. Each different “job” will do what is assigned to them. You will be doing each of the four jobs for each avitivity

The first series of activities will be spread out over the first half of the semester, the second series over the second half of the semester.
The first series will be based on systems you have seen in the Key Systems videos.
You will begin by describing at least three ideas for investigations related to the Key Systems videos. Valid ideas will ultimately be developed proposals, each of which will describe a question that could be investigated and tested using simple materials such as those seen in the videos. You will eventually develop three proposals, one of which will be chosen for an investigation. You will be the designer for that investigation.
At this point we're just beginning to explore ideas for the first series of investigations. Your instructor will work with you to further develop your ideas, and perhaps to explore other related possibilities.
Right now you don't have a wide variety of experimental techniques available to you, so this first series of investigations will be relatively simple.
List below three ideas for things you think might be fairly easy to test, based on the systems you have seen so far.
****
How a ball’s speed changes going down a ramp
How length is related to number of oscillations of a pendulum
How rate of change of depth changes over time

@&
Very good ideas.

Discuss your first idea. How do you think it might be tested? What sort of items do you think might be required? How do you think your idea might be tested?
****
The idea is that the ball’s speed increases as it goes down the ramp. You could measure the time at rest, at half way down the ramp, and at the end of the ramp. Then measure the rates from rest to half way and from half way to the end of the ramp.

Discuss your second idea. How do you think it might be tested? What sort of items do you think might be required? How do you think your idea might be tested?
****
You could test the number of oscillations in a given amount of time at different length like we have before. You would need string and a dense object to put on the end

Discuss your third idea. How do you think it might be tested? What sort of items do you think might be required? How do you think your idea might be tested?
****
It could be tested by using a two liter bottle and a clock. You could measure the rate at which the water comes out with a ruler.

Your instructor is trying to gauge the typical time spent by students on these activities. Please answer the following question as accurately as you can, understanding that your answer will be used only for the stated purpose and has no bearing on your grades:
• Approximately how long did it take you to complete this activity?
20 minutes

Very good.
We will probably wait until everyone has started to get into the collaborative labs. I'm looking forward to it.
