###### How do you intend to collect and analyze information to ascertain stakeholder satisfaction with the initiative? What information will be looked at, and who are the stakeholders that will be considered?
August 22, 2019

A.) Imagine that astronomers have discovered intelligent life in a nearby star system. Imagine you are part of a group submitting a proposal for who on Earth should speak for the planet and what 50-word message should be conveyed. Be sure to answer all three questions below, if you choose this option.

(A) Who should speak for Earth and why?

(B) What should this person say in 50 words?

(C) Why is this message the most important compared to other things that could be said?

Instructions: should be at least 200 words.

B.) Observing Jupiter’s Moons

Big Idea: Sky objects have properties, locations, and predictable patterns of movements that can be observed and described.

Goal:  Students will conduct a series of inquiries about the position and motion of Jupiter’s moons using prescribed Internet simulations.

Computer Setup:

Access      http://space.jpl.nasa.gov/ and

a) Select THE MOON in the “Show me _______ “ drop down menu

b) Select THE SUN in the “as seen from _______ “ drop down menu

c) Select the radio button “I want a field of view of ____ degrees”  and set the drop down menu to 0.5

d) Select the check box for EXTRA BRIGHTNESS and then Select “Run Simulator”

Phase I:  Exploration

1) The resulting image shows what one would see looking through a special telescope.  In this picture, where is the observer with the special telescope located?

2) How does the image change if you INCREASE the field of view?

3) What is the exact date of the image?

4) Astronomers typically mark images based on the time it currently is in Greenwich, England, called UTC.  What is the precise time of the image?

5) Using a ruler to measure the distance on the screen between the middle of Earth and the middle of the Moon, what is the measured distance?  You do NOT need to know the exact number of kilometers, but simply a ruler-measurement you can compare other measurements you make later.  Alternately, you can use the edge of a blank piece of paper held in the landscape orientation and mark the positions of Earth and Moon or the Squidgit ruler found on the last page.

6) Use the browser’s BACK button to return to the Solar System Simulator homepage.  Now, advance the time by 1 hour and determine the new distance between the Earth and Moon.

7) Use the browser’s BACK button to return to the Solar System Simulator homepage.  Now, advance the time by one day from when you started and determine the new distance between the Earth and Moon.

8) Use the browser’s BACK button to return to the Solar System Simulator homepage.  Now, advance the time by three days from when you started and determine the new distance between the Earth and Moon.

9) Use the browser’s BACK button to return to the Solar System Simulator homepage.  Now, advance the time by five days from when you started and determine the new distance between the Earth and Moon.

10) Use the browser’s BACK button to return to the Solar System Simulator homepage.  Now, advance the time by 10 days from when you started and determine the new distance between the Earth and Moon.

11) Use the browser’s BACK button to return to the Solar System Simulator homepage.  Now, advance the time by two weeks from when you started and determine the new distance between the Earth and Moon.

12) Use the browser’s BACK button to return to the Solar System Simulator homepage.  Now, advance the time by one month from when you started and determine the new distance between the Earth and Moon.

13) Use the browser’s BACK button to return to the Solar System Simulator homepage.  Now, advance the time by three months from when you started and determine the new distance between the Earth and Moon.

14) It has been said that it takes about one “moon-th” for the Moon to go around Earth.  Which of your observations confirms or contradicts this statement?  Explain.

Phase II – Does the Evidence Match the Conclusion?

15) Set the Solar System Simulator to observe Jupiter from the Sun, where Jupiter takes up 10% of the image and measure the distance between Jupiter and Io shown on the image, and identify which side of the planet Io is on.

16) Advance the “time” by one day, and record the distance between Jupiter and Io.

17) Advance the “time” by two days from when you started, and record the distance between Jupiter and Io.

18) Advance the “time” by three days from when you started, and record the distance between Jupiter and Io.

19) Advance the “time” by four days from when you started, and record the distance between Jupiter and Io.

20) Advance the “time” by five days from when you started, and record the distance between Jupiter and Io.

21) Advance the “time” by six days from when you started, and record the distance between Jupiter and Io.

22) If a student proposed a generalization that “Io orbits Jupiter about every 48 hours,” would you agree, disagree with the generalization based on the evidence you collected?  Explain your reasoning and provide specific evidence either from the above questions or from evidence you yourself generate using the Solar System Simulator.

Phase III – What Conclusions Can You Draw From the Evidence?

Europa is one of the four largest moons orbiting Jupiter.  The others are Io, Callisto, and Ganymede.  What conclusions and generalizations can you make from the following data collected by a student in terms of HOW LONG DOES IT TAKE EUROPA TO ORBIT JUPITER?  Explain your reasoning and provide specific evidence, with sketches if necessary, to support your reasoning.

23) Evidence-based Conclusion:

Phase IV – What Evidence Do You Need?

Imagine your team has been assigned the task of writing a news brief for your favorite news blog about the length of time it takes Ganymede, the largest moon in the entire solar system, to orbit Jupiter once.  Describe precisely what evidence you would need to collect in order to answer the research question of “Over what precise period of time does it take Ganymede to orbit Jupiter?

24) Create a detailed, step-by-step description of evidence that needs to be collected and a complete explanation of how this could be done—not just “look and see when the Ganymede is first on one side and then on the other,,” but exactly what would someone need to do, step-by-step, to accomplish this.  You might include a table and sketches-the goal is to be precise and detailed enough that someone else could follow your procedure.

Phase V – Formulate a Question, Pursue Evidence, and Justify Your Conclusion

Your task is design an answerable research question, propose a plan to pursue evidence, collect data using Solar System Simulator (or another suitable source pre-approved by your lab instructor), and create an evidence-based conclusion about some motion or changing position of a moon of the solar system, which you have not completed before.

Research Report:

25) Specific Research Question:

26) Step-by-Step Procedure, with Sketches if Needed, to Collect Evidence:

27) Data Table and/or Results:

28) Evidence-based Conclusion Statement:

Phase VI – SummaryPRINT YOUR NAME

29) Create a 50-word summary, in your own words, that describes the motions of the Galilean moons and how this changes over time.  You should cite specific evidence you have collected in your description, not describe what you have learned in class or elsewhere. Feel free to create and label sketches to illustrate your response.
