course ollaborative Labs
sept 15, 8pm
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:

Throughout the semester, there will be collaborative assignments with other students. Activities including being the designer, experimenter, analyzer and the interpreter. I will be able to do each task in different studies.

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.
The length of a pendulum to speed of a rolling ball on a flat surface.
The speed of different objects on the same incline.
The average speed of an object on a flat surface after going down a ramp.

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?
Having a ball on a flat surface, swing a pendulum and make it hit the ball. Calculate how far the ball goes from rest and start the time on impact and stop it when the object stops rolling. Vary the lengths of the pendulum. You would need a pendulum, a ball or rolling object and a stopwatch.

Great idea.
You would need a really flat surface, or the rolling object would tend to meander, and some parts of the surface would be more or less downhill or uphill. The same idea with the ball on a ramp, either level or with a slight uphill slope, would alleviate most of this problem.
