** **
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.
****Have two bottle set up with the same amount of water, the same markings measuring intervals, but with different size tubes, testing them at the same time noting the differences between the two.
Measure how far an liqid travels at different angles of the tube from the bottle.
See how easy (or if it is even possible) to transfer liquid from one bottle to another almost completely through a tube while squeezing the bottle.

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?
****You could set up two same sized bottles, cutting a hole in the bottle (as we did in the last experiment) toward the bottom of the two bottles in the same place, but put two different sized tubes in them, and see just how differently they react. The materials needed will be two bottles, two different sized tubes, water, and something to poke a hole in the bottles.

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?
****You can sit up this one similarly like the other one, just using one bottle and one tube. You poke a hole in it like in the other experiment mentioned, but test it out several times by holding the tube up at different angles and record how far and fast the water would flow out of the tube at each different angles.

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?
****Here we would place the tube inside the mouth of one bottle and squeeze that bottle transfering the liquid into another bottle which would have the other tube stretching into it with the bottle cap screwed on top of it so it would be sure to stay. You could record how much reached the other bottle and how long it took and how much you squeezed it I suppose.

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 minutes

Very good ideas.
We will follow up when I've received a sufficient number of responses from other students, probably within a week or so.
