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 conduct labs in groups and each time we do a lab we will have a different job/responsibility. One time I will be the designer of the lab, another time the experimenter , another time the data analyzer and lastly the interpreter of the data.

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.

how long will it take a pencil to roll down an incline?
If A cylinder filled with water has 2 holes how will that extra hole affect the system?
Will a deck of cards have as much potential and kinetic energy as a stack of dominoes?

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?
****
this could be tested by creating a ramp using textbooks or a binder as a ramp. The only thing I would still need would be a pencil and the timer program. Maybe I could even time a pen as well and compare the speeds between the two.

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?
****
I would need to obtain a graduated cylinder and puncture two holes into it. Then I could time how long it takes the water to exit the cylinder. Or I could simply observe the speed of the water as it exits the cylinder.

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?
****
Stack up a deck of cards and hit the deck with a ruler. I can observe how the deck and hypothesize how much potential and kinetic energy it has in relation to the dominoes seen in the video.

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 would say this activity took me about 15 minutes.

Thanks. We'll be looking at students' suggestions next week.
