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

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
