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:
****
There will be several participants in these types of labs one person comes up with an idea and tells how to do the test, one person will do the experiment following the instructions of the person who came up with the idea, one person to analyze and put all the data together and one person to describe what they found out.

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.
****
Idea 1: Dominos vs Car on an incline
Idea 2: Straw on a dice rotation at 180 degrees and 360 degrees
Idea 3: Pendulum velocity vs chain of rubber band velocity

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?
****
The dominos would be placed in the standing position within a half of inch of each other or less and the car would be placed on an incline. The dominos and car would have to travel the same length and will have to be timed to see which one had the greater velocity and finish time. Items needed dominos, car, book (same length as dominos), a prop for the book to create incline, ruler and timer to time each test. It can be test various was both at the same time or one then the other.

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?
****
The straw would rest on a dice with a little weight on each end of the straw to make it rotate easy. The test will be done by placing the straw on the dice and taping it with a small amount of force causing it to rotate 180 degrees and then repeating it for the 360 degrees. Items needed a straw, a dice, something for a little weight for ends of straw and a timer. It would be tested to see if the 180 degrees had a bigger velocity than the 360 degrees and to see how long it took for the rotations to complete.

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?
****
The pendulum would have a predetermined length along with the chain of rubber bands and would be tested to see which one had a greater average velocity for a certain amount of cycles. Items needed thread washer, timer, rubber bands and paper clips. It would be tested by timing the cycles of the pendulum and then timing how many vibrations the rubber band chain made in a predetermined time.

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 min

Good. We will follow up on this very shortly.
