The final exam will consist of  70 multiple choice questions and  3 short answer questions.
Each of the questions below focus on a key concept. Think about how this concept might be asked in the form
of a multiple choice question.
Unit 1: Evolution of Thought
1. What is and what is not science? (list some key words for each)
2. In science, what is meant by a fact? A hypothesis? A theory?
3. Why do scientists prefer the metric system of measurement?
4. What is the rule for taking measurements with the appropriate number of significant figures?
Unit 2: Cosmic Evolution
5. Atomic mass units (AMUs) are used to measure what types of particles?
6. How many neutrons are in sodium-24?
7. What process causes light to be emitted from an atom?
8. What happens to white light when it passes through a prism?
9. What property or properties are different between the different colors of light? The same?
10. What does a light year measure?
11. How does parallax work and why doesn’t it work for far away galaxies?
12. What is the distance to a star in parsecs that creates a parallax angle of 0.500 arcsecs?
13. What does Hubble’s Law state about the distance and speed of galaxies?
14. What elements first formed after the Big Bang?
15. What is inertia?
16. What does mass measure?
17. What is acceleration?
18. What is the difference between speed and velocity?
19. What are the units of speed, velocity, and acceleration?
20. How much does an 80 kg person weigh on Earth? (in Newtons)
21. How much does an 80 kg person weigh on the moon, where the acceleration due to gravity is 1.7 m/s2?
22. If a constant force is applied to an object, what happens to the acceleration if the mass increases?
Unit 3: Planetary Evolution
23. If a substance has a mass of 10.0 g and a density of 2.0 g/cm3, what is its volume?
24. How did the Earth form different layers?
25. Why is the interior of the Earth still warm?
26. What are the 3 forms of radiation? What are the characteristics of each form?
A small amount of extra credit will be awarded by submitting brief answers to these questions on a separate piece of
paper by the day of the final exam.
