We watched Savage Sun movie exerpts
We took notes regarding:
The Sunspot Cycle
Maunder Diagram
Space Weather
Day 2
Go to the link below. Try looking at a spectra that is 350 degrees, 1000 degrees, and 6000 degrees. What amount of visible radiation is shown in each of those? Why do we have blackbody spectra for stars?

Complete the sun lab using the sheets provided, and the link shown below

Investigate screen and experiment with the situations. Predict what will happen under the following situations:
What will happen when the voltage is increased?
With the voltage at a given amount, what will happen when the heater percentage is reduced?
If conditions are set so that light is being produced in multiple molecule mode, what will happen in single atom mode? Check your predictions.
Questions: 1. What condition(s) must be met in order for light to be produced by a discharge lamp?
2. What event(s) occurs to actually produce the light we see?
3. Does the spectrophotometer indicate unique spectrums for each gas?
4. What types of electromagnetic radiation are produced?
5. How could this phenomenon be used by astronomers?
