Another one of the main messages I hope you have gathered from this lesson is how important the study of light is to astronomers. For the most part, everything we learn in the upcoming lessons will rely on astronomical observations that rely on the tools and techniques you just studied.
First, please take the Web-based Lesson 3 quiz.
- Go to Canvas.
- Go to the "Lesson 3 Quiz" and complete the quiz.
Activity 2 - Discussion
For this activity, I want you to reflect on what we've covered in this lesson and to consider some of the most basic questions about how astronomers do astronomy. Since this is a discussion activity, you will need to enter the discussion forum more than once in order to read and respond to others' postings.
Submitting your work
- Enter the "The Nature of Astronomical Experiments" discussion forum in Canvas.
- Post your ideas about the topic I have posted to that forum.
- Read postings by other ASTRO 801 students.
- Respond to at least one other posting by asking for clarification, asking a follow-up question, expanding on what has already been said, etc.
You will be graded on the quality of your participation. See the grading rubric (identical to the one from Earth 530) for specifics on how this assignment will be graded.
Activity 3 - Lab
During this week, you should complete work on the lab exercise you began during Lesson 2.
- Lab 1, Part 2 is located on the next page.
- Perform the data analysis and calculations, and write answers to the questions.
- Submit your work to Lab 1 in Canvas.
Reminder - Complete all of the lesson tasks!
You have finished the reading for Lesson 3. Double-check the list of requirements on the Lesson 3 Overview page to make sure you have completed all of the activities listed there before beginning the next lesson.
