I've spent more time than I've had this week on physics. I know what I turned in for this assignment is week. At this point, I just need to get done with the weeks assignment.

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 two group labs this semester. I will participate as 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.

Marble rolling on plane
Paper clip rotation
Pendulum cycles
#$&*
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?
****
Find velocity of object on incline. Tested on incline with marble. Marble, flat object, ruler, timer program

@&
To make a test some quantity we control will need to vary, while some other quantity dependent on our controlled quantity will also vary.
It's not clear what quantities are expected to vary here.
*@
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?
****
Find time for paper clip to rotate. Use paper clip, push pin, timer.
#$&*
@&
To make a test some quantity we control will need to vary, while some other quantity dependent on our controlled quantity will also vary.
These quantities would be our independent and dependent variables, respectively.
What would be the independent and dependent variables for this investigation?
*@
Discuss your third idea. How do you think it might be tested? What sort of items do you think might be required? How do you think your idea might be tested?
****
Make a pendulum. Use string and weight and timer program.
#$&*
@&
What would be the independent and dependent variables for this investigation?
How specifically would we observe them?

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 minutes.

Good suggestions, but they need to be fleshed out a bit more.
See my notes and insert your responses, then please resubmit.
