Extra Credit Opportunities

Complete the electromagnetic spectrum activity....help each other.
THIS IS EXTRA CREDIT and due by May 6 if you want it added to your score


Start the activity on studying the cosmos. We'll finish this during the week of May 2-6

HR Diagrams and Stellar Life Cycles

This activity will take about an hour to go through. For each page, you should either take notes or add to a mind map.

Each person will turn in their own detailed document.

The Telescopes in the Sky

WATCH THE VIDEO. This is connected to your review and the giant space telescopes.

Take a look at Chandra, the x-ray telescope

Wednesday, 4/20

Go to the neon discharge tube lab at PHET. Use it to answer the following questions.

1. Gather evidence to prove that different elements have unique characteristics (hint: use a PrtSc button and paste into a Word document)
2. Explain, step-by-step, how a single electron is excited by a discharge lamp
3. Compare step-by-step emission to a continuous stream emission.
4. Using JUST the applet, not a google search, how do you think fluorescent light bulbs work? (hint: do all line spectra need to be visible?)

Be ready to hand this in tomorrow.

==============Poster

Create a poster that talks about emission and absorption spectra, and details how they can shift due to rotation, red shift, or blue shift. use your book to do this.

Galileo and the Moons of Jupiter

Galileo became a heliocentrist largely due to his observations about Jupiter's 4 biggest moons:  Io, Europa, Ganymede, and Callisto.  Using his telescope, he observed these moons and their patterns around the planet.  He marked the motion of the moons in terms of Jupiter Diameters as viewed through his telescope.

Set up a Open Office Calc table with the names of the 4 moons at the top and the dates on the left side.

Gather data for at least 30 days using the Jupiter moon position applet a

Create a x-y scatter graph for each moon.

Hand in with you and your partners' names by the end of the period

Designing your Travel Brochure, part 2

You'll need to think about the sights to see along your trip from the perspective of a tourist.   Are there noticeable features to see?   The possibility of surfing in an alien ocean?  Fossil studies to go to?

Assume you will spend at least a month at each location.  Is there a 'top 5' list you should visit, in terms of geological significance (plates, volcanoes, oceans, landmarks?).  You should already know this

How long will it take to get there?  To do the math, use the distances found in an orrery.  Here's one and here's another sample that would have been useful yesterday (thanks, Josh)


While your spaceship may travel at the speed of the space shuttle, it may take a while to get there.  Will you have a lovely greenhouse?  Special spacesuits designed for ventures outside the planet?


Your brochure must be ready by Monday.  I would suggest a shared google presentation or folder that can serve as a 'digital brochure.'   Let me know if you need some help.

This is a 40 point project, which means it is as valuable as a test.   Choose wisely what you will do.

Comparing the planets

Part 1:  Start with the circular orbital sets found on my desk. Our Earth is the 'third rock from the sun'.   Figure how much of a year is represented by the 24 cards, and compare that orbit in proportion to the orbit of a) Mercury and b) Mars.   Note what direction the planets are moving during the time frame.
a) How much of a year is represented?
b) One Mercury year represents how much of an Earth year?  Explain your answer.
c) Repeat for Mars.

When you are done, turn the yellow cards and your work in, on individual paper.

Part 2:   Get into groups of 3 or less. You will be comparing one of the following sets.   Not everyone can choose the same set, so pick wisely so it is distributed across the class.  If you are not working, I will be disappointed.  While I do not expect you to complete the entire project, your research should be done, and you should be started on the brochure.

• Mars and Neptune and Earth
• Mercury and Saturn and Earth
• Our Moon and Titan and Earth
• Venus and Uranus and Earth
• Ceres and Jupiter and Earth

You may start by looking here, as well as looking at the materials I have given you, the textbooks, and the Nine Planets.  Any other resources must be referenced in the body of an email.

Organize your materials in a t-chart format.  At the end of the hour, give it to the substitute.

Your goal tomorrow is to create a travel brochure that will move you from one location to another.  You must include an itinerary of events, how the magnetic field and your weight on the locations will matter, the probably time frame, assuming you travel at space shuttle speeds, safety equipment needed and a variety of visuals.   The brochure will be printed in color for grading; please send the completed document to my gmail address.
