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:

In order to promote teamwork, collaborative labs were created. They feature groups of four individuals that work together to complete objectives. Each individual has their own part in the process; these parts are designer, experimenter, analyzer, and interpreter. Each person will get a chance to be assigned each part of this process so everyone can participate in different ways.

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.
****
1. Testing the washer and pendulum to see if they hit at the same time.
2. Testing different parts of the flow from a cylinder such as does the flow rate slow down or speed up and the length that the liquid flows out from the cylinder.
3. Testing what proportion of different sized beads bounce to the top of the slanted box as shown in the experimental video.

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?
****
We could set up a washer and a pendulum like in the video but from different heights to see which the best set-up is so that they both hit their surfaces at the same time. Also, we could test to find out which angle is the best to hold the pendulum out to before releasing.

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?
****
Setting up the cylinder with a hole in the bottom and allowing water to flow out from it. Then measure the horizontal distance that the water travels at different height intervals on the cylinder. Also, we could test to see if the rate of flowing water out of the cylinder slows down or speeds up over time at different time intervals.

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?
****
Using a box and some beads, test the theory that the more of one kind of ball you have in the box, the more likely it is that it will reach the top. Another good reason for this is to see first-hand how the balls reach the top if the box is tilted downward by just a simple side to side movement.

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 minutes.

Very good ideas.
I'll get back to you soon, when I've gotten a few more responses from students in your course.
