Collaborative Labs
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:
****
For the Collaborative Labs, we will be put into groups of four where each individual will have a specific job to complete, the four jobs are the designer, the experimenter, the analyzer, and the interpreter. For each activity we will help with a different job.

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.

Similar to the car rolling down the incline, an object could be dropped from a certain height and using the TIMER program you could find the velocity, etc.
Another experiment that could also work with the first idea would be to throw the object up from a certain height and use the TIMER program to estimate time until it hits the ground, find how high the object travels, at what speed it travels upwards and at what speed it travels downwards.
Another idea is to watch cars drive by your house and estimate the distance, velocity, and time it takes them to get from point a to point b.

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?
****
It would be tested by dropping an object from a height of how tall the experimenter is and then velocity, distance and time can be calculated. The safest item to drop would be a ball, a measuring tape would also be needed if you don’t know exactly how tall you are.

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 second idea would be tested by choosing a distance from the ground to throw the object upwards and then timing how long it takes to reach its maximum height and how long it takes to hit the ground. Here the safest object might also be a ball, a ruler or yard stick would also be needed.

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 third idea could be tested by resetting the mileage in your car and driving from point a to point b. Using the mileage and time traveled one could find the average velocity. Here you would need a car or using an app on a cell phone you could walk, run, or ride a bike.

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?

`` Thanks. Your ideas look good. I'll get back to you soon on the collaborative labs, after receiving a responses from a few more students.
