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?

Using two rubber bands and a paper clip to make a sling which can hold the rubber band and pinning them down down with pins on the plywood we can then use the timer to time the ball
We can measure the rubber bands and the tension and force they have and we can see how much the force propels the rubber band and how much was taken by external circumstances such as friction by calculating how far it should have gone.

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?
****
Use a string attached to a bag which holds objects of a known weight, attach the magnets together around the string to hold it in place. Put the magnet on a metal surface and place objects in the bag until the magnets no longer can hold it up (or till the string breaks) and possibly test it with other magnets to find the force of various ones.

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?

A measure of how the length of the string of a pendulum affects the total number of oscillations before the pendulum stops. By actually using the pendulum and counting the oscillations at various pendulum lengths. A washer and a string and a measuring device.Still as said before its asked above

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 min
