1. 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 lenses and telescopes work
Understand and describe the quantization of energy at the atomic level
Understand that all objects emit and absorb electromagnetic radiation and distinguish between objects that are blackbody radiators and those that are
Qualitatively describe the shift in frequency in sound or electromagnetic waves due to the relative motion of a source or a receiver

2. Learning Goals: What is electromagnetic radiation?
What can different types of electromagnetic radiation reveal about astronomical objects?
What are the important properties of electromagnetic radiation and how are they typically organized?
What can be learned from analyzing the light from astronomic objects?
How is technology used to collect electromagnetic radiation and turn it into images?

3. Finally
Spectrum Analysis
Light
Analysis

4. Lab/Observation Day Follow directions
Cut the sheets out and glue in your journal at end
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 to next table until we rotate
When you rotate, please be careful! These are hundreds of dollars each!

5. Your Paper Should Look Like This at the end

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

7. Ar H He Hg I Kr Ne

8. Emission Spectrum of Each Element

9. 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 be careful with the expensive equipment
DO NOT TOUCH THE BULBS!!
Please leave your markers at the lab station!
Put them back into their box. 
We wont finish them all today
We will do half today and half tomorrow

11. Light Entrance
Light for Ruler

12. You have to get really close
Yes No

13. If you have hair….Don’t get too close

14. Sometimes it is very hard to see

15. There is a station at my desk with a candle
This is also a station where you must go outside and look at the spectrum of sunlight
Don’t stare at the sun!
DO NOT TOUCH THE BULBS!!
Try to figure out which bulb corresponds to each element
