** **
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 cooperating with a group of people for this experiment. Good ideas will become proposals. There are four different people we can be as stated above: designer, experimenter, analyzer, and interpreter.

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.

Using the Timer Program
Using standard Deviation to further answers
Pendulum

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?

I would use the timer program in a different way than we have seen. I would ask the student to test how fast the rolling car goes from beginning point to the end, but I would increase the distance. It would be a set of three trials with the student then recording the average and standard deviation, after finding out the difference in the distances and speeds.A rolling car would be used as well as the timer program and a start and end point. A calculator can be used for standard deviation and average.

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 have a graph with 5 different lines through it. This could be a graph about the ball if they wanted it to be (just to tie it in with the previous question). Take the points, and find the average and standard deviation of both the X and Y axis. Are the answers similar at all? Why or why not? Did you think they would turn out like this just by looking at the graph? Simple construction paper and pencil would be used for this problem.

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 experiment would be different. Tie a tire to a rope in a large enough tree to hold it. Use the Timer program to complete 30 trials from the tire's beginning point. Make sure to see if your answers are accurate by performing this a couple of times. Find mean, median, mode, and standard deviation. Make predictions of what you think they will be beforehand, and then test those predictions. Materials needed: Tire, rope, tree, pencil, paper, calculator.

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?
About 30 minutes.

Excellent ideas. I like your thinking.
