Your 'collaborative labs' report has been received. Scroll down through the document to see any comments I might have inserted, and my final comment at the end.
** Collaborative Labs_labelMessages.txt **
** **
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?

My first idea is in the lines of the optical interference, where more complex patterns can be used with patterns that increase its distance from each other. Along with different patterns, the student can test the shining of laser through the pattern through different distances from the wall as well as the transparency. My idea can be tested through the using of laser and transparency with patterns.

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?

My second idea is to identify the components of a concave mirror which include focus point , distance of object, distance of image , height of image and object through measurements and experimentation with the mirror . First the student observes the mirror through trying to find the focal point and so on and later he/she uses measurements and numbers to find the actual measurements and see if it was right with his/her observation. The supplies needed include a concave mirror and an object of choice.

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?

Repeat the focusing light thru cylindrical lens experiment but which alcohol and colored beverage to see if that affects the results gained and then compared and contrast with the control of the experiment which is the water filled cylinder.

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?
20 minutes

All of these are excellent ideas. I'll follow up soon.
