To prepare for this Assignment:
• Review Walden University’s General Education Learning Outcome: “Change” in the Syllabus. Consider how the General Education DEEP-C model contributed to your ability to discover and evaluate ideas from different perspectives, and is instrumental in your progress toward achieving personal goals and effecting positive social change.
• Revisit definitions of social responsibility shared in the Week 1 Discussion in light of all the information you have considered throughout this course.
• Read Chapters 11 and 12 in the Loeb (2010) course text.
• Reflect on the exercise in collective action represented by the Group Project. Think about the benefits collective action offers for accomplishing the goals of the Group Project.
The Assignment:
Write a 3- to 4-paragraph journal entry in which you briefly analyze the value of collective action in working toward social change.
• Describe how your perspective has evolved or changed through this course and how you believe it will continue to evolve after the course.
• How has this experience influenced your ability to create positive social change beyond the term of this course?

2. Estimating The Number Of Stars In The Night Sky
For this experiment, you will need an empty toilet paper roll and a clear, dark night. Before you start, jot down the number of stars that you think you can see in the night sky.
Aim your toilet roll at a part of the sky well above the horizon to avoid any haze pollution. Hold your roll steady and allow your eyes to get used to the light for a few seconds. Count the number of stars that you can see within through the roll. Do this four more times in other parts of the sky, and average the five counts.
The viewing diameter of a toilet roll is about 1/135th of the entire sky, at least for a relatively flat area. Mountains, buildings, and large trees will obscure some of the sky. To determine the number of visible stars, multiply your average by 135.
1. Light And How We Read It
Building a Spectroscope and Analyzing Spectra
For this module you will be required to build a spectroscope. First review the instructions to build a spectroscope, and then watch the following video.
Make Your Own CD Spectrometer
Summary: Dr. Andrew Steele shows us how to make a spectrometer, a device used by scientists to analyze light, using a cereal box and a CD.
Your CD or DVD will not be harmed in the process, but please don’t risk discs you would rather keep.
A spectroscope breaks incoming light into its individual components so that the original source can be identified. Once you have built your spectroscope, you will test various light sources and answer questions regarding those sources.

For Your Success:
This is a fun series of labs, though the first one is a bit labor intensive. You won’t want to wait until the last minute to start it.
Learning Outcomes:
1. Describe how scientists gather information about other star systems.
2. Calculate how many stars are visible to the average human.
3. Reconstruct the relative scale of the solar system.
