Explore 1. Look at each star and its spectrum. It might help to print out all the spectra so you can compare them all.

Study the spectra carefully and answer the questions below.

Question 1. What do you notice about the spectra? What are the most important features they all have in common?

Question 2. What differences do you notice among the spectra? How do the features you identified in Question 1 change among the 14 spectra?

Question 3. Do you notice a relationship between a star's color and what its spectrum looks like?
