** **
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?
for the first idea, one person could be sitting on a bike and coasting down a hill. this person would not pedal at all. The hill would be marked with distances and cones to know when to push the timer button. As the person on the bike coasts, the individual with the timer porgram would hit timer at each cone. SInce the cones would correspond to distances, the information could be used, along with the equations for uniformily accelerated motion, to find the acceleration down the hill. This would be fairly easy to test and would only require cones, a bike, some tool to measure with, and the TIMER program.

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?
This could be done by using individuals of varying weights or objects of varying weights (if this was done something besides a bike would be used because the bike would not balance without a person). The same process as above would be done, however, this time a new trial would be conducted for each weight. The weights vs acceleration could be graphed and the graphs compared to decide if weight had an effect on acceleration. This lab would require the same materials as above, along with weights (or people of different weights), and graphing paper.

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?
This lab would be relitively simple in terms of items required to complete it. Each individual finds their percent error for a best fit line. These percents would then be added together and divided by the number of people to find the average percent error.

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?
About 20 minutes.
