3. 4. Complex Knowledge: demonstrations of learning that go aboveand above and beyond what was explicitly taught. 3. Knowledge: meeting the learning goals and expectations. 2. Foundational knowledge: simpler procedures, isolated details, vocabulary. 1. Limited knowledge: know very little details but working toward a higher level.  understand the electromagnetic spectrum and how it is organized.  understand what different types of electromagnetic radiation can reveal about astronomical objects.  understand and describe important properties of electromagnetic radiation.  understand how technology is used to collect electromagnetic radiation and turn it into images.  understand what can be learned from analyzing the light from astronomical objects.  understand how different types of telescopes work  understand how lenses are used in telescopes.

4. Finishing up

5. Lab/Observation Day  Cut the sheets in half and glue/tape in your journal You only need 3 this time….this will give you enough to finish the lab.  Follow the directions on the lab Make sure that everybody has a chance to look at each station It will be easier the closer you get to the light source Please don’t go ahead until we rotate (it’s going to be dark 

6.  Keep track of the numbers at the bottom (wavelength in angstroms)  Refer to the screen at the front to figure out which element you are looking at  Please take your spectroscopes, diffraction gradients and your colored pencils with you!

7. Lab Day Part 2

8. When you are done…  Read the part of the lab that says “Read”  Do the part of the lab that says “Do”  Answer the question after the part of the lab that says “Question”  Answer the questions at the end of the lab  Come up and show me your completed lab for credit!
