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.

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:

There are four main parts and jobs in the activities given throughout the semester. One of these jobs is the designer who develops the idea and manages the other members functions.
The experimenter conducts the experiment based on the instructions given by the designer.
The analyzer analyzes the data that was produced by the experimenter.
The interpreter explains and describes the results.

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.

What qualities stay constant of an object going down differing sloped ramps with the same height and width?
Calculating the period of an object based on the length of string and seeing how the differing times relate to eachother.
Differences between a cylinder rolling down an incline and a sphere.

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?
****
My first idea is seeing whether there are many similarities such as final velocity and time traveled between the same object on differing ramps. This would be tested using trials with two differing ramps with the criteria stated above, a timer and a rolling object such as a ball.

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?
****
The second idea is testing the period of the same object using different lengthed strings. To test, several trials of a long lenth of string and a short lenth of string period will be timed and comparisons will be done. A semi heavey object, two different sized strings and a timer will be needed.

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?
****
The third idea is testing a cylinder and a sphere down the same incline. Timing several trials of each will allow for ideas to be expanded. A cylinder, sphere, timer and on incline will be needed to test this.

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?
****
30 mins

Good ideas. Once I've received responses from the other students in your class we'll begin organizing the project.
