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 participating in 2 series of collab lab activities. The first will be used to begin to develop a degree of teamwork and collaboration. Four parts of a group: the designer, the experimenter, the analyzer, and the interpreter
#$&*
The first series of activities will be spread out over the first half of the semester, the second series over the second half of the semester.
The first series will be based on systems you have seen in the Key Systems videos.
You will begin by describing at least three ideas for investigations related to the Key Systems videos. Valid ideas will ultimately be developed proposals, each of which will describe a question that could be investigated and tested using simple materials such as those seen in the videos. You will eventually develop three proposals, one of which will be chosen for an investigation. You will be the designer for that investigation.
At this point we're just beginning to explore ideas for the first series of investigations. Your instructor will work with you to further develop your ideas, and perhaps to explore other related possibilities.
Right now you don't have a wide variety of experimental techniques available to you, so this first series of investigations will be relatively simple.
List below three ideas for things you think might be fairly easy to test, based on the systems you have seen so far.
****
1.) A relationship that exists between an objects mass and pendulum
2.) When speed is decreasing is there a difference between a motion that rotates and a motion that stays straight
3.) Will an angle of a ramp effect the distance that a toy car traveling down will go.
#$&*
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?
****
Have an L shaped piece of metal and various lengths of string to use as the pendulum. You will also need a variety of masses to attach the pendulum. The data program and timer program would be used to analyze and record the data.
#$&*
Discuss your second idea. How do you think it might be tested? What sort of items do you think might be required? How do you think your idea might be tested?
****
I would use a straight ramp and possibly something similar to a water hose, and let a ball travel down each one. I would use both the data and timer program.
#$&*
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?
****
I would set different slopes for the ramp and roll a toy car off at each slope and measure the distance from edge of table to the impact point with of the floor. Then I would use the data program to find mean and standard deviation for each slope of the ramp.

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?
45 minutes

You have completed the first series of collaborative labs.
In that series you developed some important skills with teamwork, collaboration and communication. By now you have also developed additional lab techniques and insights, as well as an expanded understanding of physics and the standard formulations of motion, energy, momentum, forces and other topics.
You now have a good idea of the function of each member of the team, the designer, the experimenter, the analyzer and the interpreter.
You are also familiar with the items in your lab materials package.
The second series of activities will be spread out over the remainder of the semester. The investigations in this series will be more substantial and extensive than those of the first series, though we will limit the scope to keep the workload reasonable.
Please give a brief statement of three proposals for the second series of investigations, relevant to the topics of the labs you have performed and/or the material covered so far in the course. It should be possible to conduct your proposed investigations using the materials in the lab package, and/or common items you can expect your team members to have.

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?
****
Setup a sloped ramp. Use the 3 different sized balls and discover which size goes the furthest off the table and which one gets from the top of the ramp to the bottom of the ramp the fastest. Is there any relationship to the results?
#$&*
Discuss your second idea. How do you think it might be tested? What sort of items do you think might be required? How do you think your idea might be tested?
****
Have two ramps facing each other and roll the different sized balls down one ramp and measure how far it travels up the other.
#$&*
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?
****
I would perform the domino sliding lab but instead of a flat surface use a slightly inclined surface.
