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.

1- Test to see how a ball rolls down a ramp from different heights.
2- Amount of oscillations in a pendulum when magnetic forces are included.

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?

Test to see how a ball rolls down a ramp from different heights.
The ball would start at rest and then roll down the ramp to see how far it travels. We would change the ramp height using dominoes. A ruler would be needed also.

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?
****
Using a pendulum test how many oscillations occur with magnets on one side of the pendulum. Attached to the pendulum would be a magnet also. This would be interesting seeing how the magnets are attracted and/or repelled and how it effects the amount of oscillations.

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?
****
Test the force exerted on a rubber band with various amounts of dominoes attached to one end (ie. different weights). See how much each of these rubber bands move the dominoes and how much they stretch.

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?
15 minutes

`` Thanks. Your ideas look good. I'll get back to you soon on the collaborative labs, after receiving a responses from a few more students.
