  • Nuclear fusion
  • neutrinos


  1. Draw a picture of the Moon inside the Earth showing its size compared to Earth.
  2. Develop some arithmetic problems comparing the weight of a person on Earth with the weight of a person on the Moon. Example: How much would you weigh on the Moon if you weighed 60 pounds on Earth? (Answer 10). You can do these as fractions (1/6 x weight on Earth = weight on Moon) or division (weight on Earth divided by 6 = weight on Moon). Be creative!
  3. Write a research paper comparing the various evolutionary ideas about the origin of the Moon with the true account found in Genesis 1.
  4. What is God’s special purpose for the Sun?
  5. How big is the Sun?
  6. What distinguishes the Sun from other stars?
  7. Discuss some scientific and Biblical problems with the ‘nebular hypothesis’. See also:

Additional information

Please note: The explanation given in the book about nuclear fusion as a source of energy for the Sun is out of date. Recent results indicate that nuclear fusion is, in fact, a primary source of energy for the Sun.
