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:

The collaborative lab idea is best given to evaluate everyone's knowledge not only on the subject but on the importance of working together and distibuting the work properly. Also each person must be very fluent and neat in their work before they pass it on to the next person or else important infromation may be lost.

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.
****
1.) the time it take for two different sized objects to fall from different heights and see how gravity acts on each of the objects.
2.) The maximum number of times a pendulum can sing with the shortest string possible.

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 two objects will be held from different heights but the higher the height the heavier the object and vice versa. This test will prove how equal gravity can be and how the sixe and weight of the object can influence its path while falling.

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 pendulum will have the shortest string that can be made for it in order so that it can time very fast events like flashes of light and also the extinguishing of flame. The speed of the pendulum will be extremely fast but the pendulum will have very little velocity so it will stop rather quickly.

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?

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

@&
Thanks.
Your second idea is intriguing, but is technically more difficult so we'll probably go with your first. The other idea might be a good possibility for the second set of collaborative labs.

I'll get back to you soon with instructions.
