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:

Labs will be conducted in teams of four. The designer thinks up the experiement and creates the instructions for it. The experimenter follows the designers instructions in order to conduct the experiment. The Analyzer analyzes the data obtained by the experimenter. The interpreter figures out what the the results of the analysis mean.
#$&*
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.
****
Determine relative densities of liquids using temperature
Determine relative flow velocity based on height of water column
Determine effect of multiple exits on flow

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?
****
Determine relative densities of liquids using temperature
Have three bottle-cap and tube set ups each with the same volume of different liquids - tap water, rubbing alcohol, and salt water.
Place each set up in bowls and add hot water (not boiling) to each bowl.
Determine the maximum height to which each liquid rises up the tube.
I believe we could determine the relative densities of each liquid from the results of this experiment.
Items required
3 Bottles
3 Caps
3 tubes
3 bowls
3 liquids
Hot water
We could save on supplies by reusing the same bottle set up three times. We just need to find a way to control for temperature of water. Kitchen thermometer should work.
@&
Excellent idea. The pressure in the different bottles would presumably all increase to about the same level, supporting higher columns of less-dense fluids.

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?
****
Determine relative flow velocity based on height of water column
Use a soft drink bottle with three tubes at specific heights that provide drains to the system.
Plug two holes for each trial and leave one tube open.
Determine how fast water exits the bottle at each tube height.
Items required:
Bottle
three tubes
@&
Another excellent suggestion.

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?
****
Determine effect of multiple exits on flow
Use a soft drink bottle with three tubes at specific heights that provide drains to the system.
Plug two holes for each trial and leave one tube open.
Determine how fast water exits the bottle at each tube height.
Determine maximum horizantal displacement of water.
Record these results for each tube height.
Then conduct one trials where all tubes are open.
Compare the changes in velocity and displacment versus when the tubes were only opened individually.
Items required:
Bottle
three tubes
@&
Also very good.

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?
40 minutes

@&
You've got three great ideas. For the first experiment we'll probably go with the simplest suggested setups and concentrate on the collaborative process.
