Your 'collaborative labs' report has been received. Scroll down through the document to see any comments I might have inserted, and my final comment at the end.
** Collaborative Labs_labelMessages.txt **
How is this going to work between the other class mates? How will we communicate and are any others in Phy 242? I would like to know more information about the group process.

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:

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.

Each of the 4 team members comes up with an idea for the activity, be the experimenter to set up the experiment and collect data, analyze the data, and interpret the data and results. As the investigation goes on, you will follow the work of each of your fellow team members.

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?

Will different size marbles effect the velocity at which they roll down an incline from rest? To test this idea, we could make a ramp with constant incline, and make a notch at the top for which 3 different size marbles sit. We could use TIMER program to time the marble until it hits a mark at the end of the incline. We would need three different size marbles, 5 dominos for height, a folded piece of paper to form a v-shape ramp, and a pen/pencil.

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?

Which hits first: a washer on a pendulum hitting a wall or a washer being dropped toward the ground at the same height? We would need 2 washers, a piece of string, a ruler, and a wall for this experiment. against a wall, tape a piece of string and measure 8 inches down from the tape to tie your washer. Measure 2 inches from the wall and pull back the washer to this point. Hold the second washer next to the pendulum. Let go of both at the same time and watch which hits first.

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?

How do different objects tied into a pendulum effect the frequency, period, and amplitude of the system? For this experiment we would need string, a washer, a paperclip, a domino, and timer program. I would tape the string to a wall or overhang and measure 7 inches or so from the tape and tie one of the objects to the string. I would pull back the object a certain amount each time and let go, timing each time it makes one full swing back and forth. I would then analyze the data to see it the objects effected the amplitude, period, and frequency.

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?

Thanks. We'll be organizing this project soon.
