1. What makes up white light?
2. What happens to the colors that get absorbed?
3. What is a green house?
4. What are the seven colors of the Newtonian rainbow?
5. Which "color" in the Newtonian rainbow does not seem to be a separate, different color?
6. If you were in charge of replacing the color above in the list of seven rainbow colors, what color would you replace it with?
7. What is reflection?
8. What is refraction?
9. Plot the following data on the graph provided and draw a linear best fit line through the data points on the graph.
   
   1. ______________ Calculate the slope of the linear best fit line. The slope is the experimental index of refraction for the material.
   2. ______________ __________ Use the equation of the best fit line above to predict the image depth for a coral head that is 200 cm underwater.
   3. ______________ The above material is reported to have a theoretic index of refraction of 1.5. What is the percentage error for the slope you calculated based against a theoretic value of 1.5?
10. 
    1. __________ _____ How much current does a Singer 3116 sewing machine use?
    2. __________ _____ What is the voltage for a Singer 3116 sewing machine?
    3. __________ _____ How much power does a Singer 3116 consume?
    4. __________ _____ How much resistance does a Singer 3116 sewing machine generate?
    5. __________ _____ If cash power is $0.47 per kWh, how many hours can the Singer run on 1000 watts of power?
    6. __________ _____ If cash power is $0.47 per kWh, calculate the cost to run the sewing machine for eight hours.
11. Plot the data below on the graph provided. Draw a best fit trend line through the data.
    
    
    ____________ ________ For the data above, what is the resistance?
12. 1. __________ What is the atomic number of Zn?
    2. __________ What is the atomic mass of Zn?
    3. __________ How many protons does Zn have?
    4. __________ How many neutrons does Zn have?
    5. __________ How many electrons does Zn have?
    6. ____________________ Zn was an element tested in the electrical conductivity, what is the full name for Zn?
13. Remember that the number of neutrons equals or exceeds the number of protons. The number of protons cannot exceed the number of neutrons in a stable element. Thus the more numerous nucleons are the neutrons.

15. _______________ In general, what color do acids tend to turn floral pigment fluids?
16. _______________ In general, what color do bases tend to turn floral pigment fluids?
17. _______________ Are lime fruits acid, base, or neutral?
18. _______________ Is baking soda an acid, base, or neutral?
19. _______________ Is ammonia an acid, base, or neutral?
20. _______________ Is a bar of hand soap an acid, base, or neutral?
21. _______________ Is laundry detergent an acid, base, or neutral?
22. _______________ Is bleach an acid, base, or neutral?
23. _______________ Is vinegar an acid, base, or neutral?
