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:
****
We will participate in collaborative labs. The teams will have four members, each with their own job. Each person will have each job once.

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.

Using the straw rotating on the die we could test different weights on the end of the straw. We could also test different size dice. We could also test how the length of the rubber band chain effects how long it takes the pulse to travel down the chain

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 first test could be done just as it was in the original video, but with various weights on the end of the straw. Different weights could include a push-pin(thumbtack), pen lid, or maybe even a dime if it didn't tip it over.

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 would be carried out just like the original video, but the die would be changed to a different size or possibly a different object. I can't think of a good substitute object right now.

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 experiment would consist of a rubber band chain connected to fixed objects. A pulse would be sent down the chain and the time it took to travel down and back would be recorded. Rubber bands could be added or subtracted and then the experiment would be repeated to see how much of an effect the length of the chain has on the time for the pulse to travel

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?
I took about 5 minutes on this assignment because I just saw your email and I am in a hurry to leave my house.

@&
All your ideas are very good.
The third is very similar to an experiment you will be doing so we won't use it here, but you might consider modifying your idea for the second round of collaborative labs.
I'll be back to you soon.
