There will be two collaborative lab activities over the semester. The activities will be for teams of 4, each with a specific function of: designer, experimenter, analyzer, and interpreter. For each activity you will participate in four different investigations, with a different job each time.
#$&*
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. The relationship between the angle of an incline and the distance a ball rolling off it will go.
2. The difference between rotational and straight-line motion when slowing down.
3. The relationship between pendulum length and mass when compared to frequency and period.

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?

This is to determine the relationship of the angle of incline and the distance any type of ball rolling off of it will go. The angle determines the slope, and the slope determines the intitial velocity. To be tested, I would need an incline, a protractor to measure the angle, and some way to mark where the ball lands. To test it, I would do several trials of rolling a ball off of an incline, with the inclined changed to various angles. The data would help determine the relationship.

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?
****
For my second idea, I would test the difference between rotational and straight line motion, specfically the rate of slowing down for each. To test this, I would need a timer, objects to use to simulate a rotational motion system and a straight line system, and a way of measuring distance for each. To test it I would accelerate each system for several trials, and record the rate at which each slows down.

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?
****
For this idea, I would test it using a pendulum, with several diferent string lengths. I would have a timer, and record data for frequency and period. I would take several trials of different pendulum lengths, and record the frequency and period for each so I can compare the results and analyze the data.

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.
I'll be getting back to you soon on this.
