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.

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?

Idea: conductivity through different mediums. Fresh water, Salt water at different temperatures using nine volts of DC current. Using the information recorded in this experiment we should

be able to come up with the coefficient of conductivity for each material.

The information will be recorded in a spread sheet with the range of temperatures on the right and the volts measured across the top

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?

Second idea: using clear plastic tubing and some T fittings, a peice of plywood and some pipe clamps we can set up an apparatus to inject different fluids all different densitys and colors

we can come up with the density of each fluid by measuring the volume each takes up in the plastic pipe in relation to water it will stabilize.

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?

Measure the spring constant in a rubber band using a marble, a flat friction free surface and a grade of some sort. Using the rubber band to propel the ball up a

grade until kinetic energy 1/2mv^2 is equal to potental mgh. Using the formula for conservation of energy we can solve for k. Use different slopes and get an average

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?

15 min

Excellent ideas.

We willl follow up in the next week or two.
