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:
****
As part of the course requirement we will be required to work in groups of four, which includes a designer, experimenter, analyzer and interpreter. This will involve sharing of ideas and working with each other on a chosen topic.

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.
****
Based on the systems i have come across so far i think it would be
fairly easy to use the timer program and create and experiment to
use the program.
Also the data program can be used in analyzing of data in a specific
topic that involves alot of manipulation of data.
Also from a previous program i have used in physics I we can use
celestia and create an experiment on measuring the radius of different
planets.

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?
****
Timer program can be used in an experiment that involves calculating the
displacement vs time experiment.
@&
There definitely are experiements that can be conducted in which an object is timed as it moves between two points. You might think about how to do the most accurate possible timing using the TIMER program. What would you time? What timing techniques would you want to compare?

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?
****
Data program is a very interesting program that can be used
in manupilation of data, for example obtaining data from a national
data website and finding out mean, quotient difference in realation
to how demand and supply of certain commodities or government reasources.
@&
Using the data program doesn't constitute an experiment, though there certainly are experiments that could be conducted and analyzed using the program.
Not all students will be familiar with the program at this point, but this could be a good idea for the second round of collaborative labs.

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?
****
Celestia is a free software that can be used to travel to different
planets and can also be used to calculate the orbital raidus of
different planets.
@&
I haven't used this program, but it sounds interesting.
However the program very likely uses calculated results, with no inherent uncertainty, so there would be nothing to actually test, except that the program uses its equations correctly.
So, interesting as this sounds, it doesn't seem that it would be appropriate to a lab experiment.

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?
#$&*
3o minutes
@&
You have some good ideas.
I'll be getting back to everyone with specifics within the next few days.
