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 be doing 2 collaborative lab activities through the semester. They will depend upon groups of 4 where each person will be assigned a task of either designer, experimenter, analyzer, or interpreter. The designer will create the activity and outline the procedures. The experimenter will collect data from the designers instructions and execute the activity. The analyzer will describe the results from the data and group them in a meaningful way. The interpreter will take the analyzers results and explain their applications in a meaningful way. In each collaborative lab activity each person will have all 4 roles at some point.

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.
****
Straw on a die spinning, try it on different surfaces like carpet, asphalt, wood, countertop that would have different amounts of friction and see what effect it would have on the motion of the die
Using a rubber band chain, Use different length rubber bands + thicknesses of rubber bands to see if they make a difference on the motion of the chain.
Test how different fluids will flow differently out of graduated cylinder.

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?
****
Set up the straw and die just like in the video on each of the surfaces, tap each one with the relative same amount of force and see how long it takes to stop. This one would probably require a stopwatch or the TIMER program in addition to the materials seen in the video.

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?
****
This could be tested by changing the number of rubber bands in the chain or by using different types of rubber bands and filming its motion. This one would be harder to test though.

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?
****
For the third one this could be tested using the same graduated cylinder as in the video (which should be included in our lab kit). And using different household liquids like water, detergent, oil, orange juice, soap, etc. The key would be to have a ruler under the graduated cylinder to look at how the flow changes with time. This could also be done just using water if the incline of the graduated cylinder was changed and the degrees of change were measured.

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?
10 minutes

Good ideas. We will be organizing this project soon.
