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.

Use multiple rubber band chains to observe the effects of superpositioning
Attach a “heavy” rubber band chain to a “light” rubber band chain and observe how the waves transfer between the two when plucked.
I’m having trouble coming up with ideas for this set of labs. Most of the ideas I have are for experiments that have either been performed as coursework, or as the experiments on cds. If neither of the first two are adequate, I would appreciate any help you can offer coming up with a basic premise to test.

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?

Attach a long rubber band chain to two fixed points. Attach a second shorter chain to one of the same fixed points and attach the other end to the first chain so that they are running more or less parallel. Pluck the two chains at the same time/different times and observe the effects on the length of chain beyond where the shorter chain is attached.

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.
****
Attach a chain made up of heavy rubber bands and larger paper clips to a smaller chain of rubber bands with smaller paperclips. Pluck each end and observe how the waves transfer to the smaller or larger chain.

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?

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?
Not long for the actual write up, but I have been thinking for several days and have come up with little.
