 Identify,
adapt, or invent a sport that people on the moon will find interesting,
exciting, and entertaining. Write a proposal to NASA which
includes the following: a description of your sport and its
rules and how it meets the basic requirements for a sport; a comparison
of factors affecting sports on Earth and on the moon in general; a
comparison of the play of your sport on the Earth and on the moon
including any changes to the size of the field, alterations to the
equipment, or changes in the rules.
 Research
how the work of scientists Antoine Lavoisier, Isaac Newton, and Albert
Einstein related to the study of mass. To what extent are
their ideas compatible or contradictory? Present your
findings or use an A Layer Assignment form.
 In
recent years, many Olympic athletes, such as sprinters, swimmers,
skiers, and speed skaters, have used modified equipment to reduce the
effects of friction and air or water drag. Research a piece
of equipment used by one of these types of athletes and the way it has
changed over the years. Explain how physics has impacted
these changes. – Use an A Layer Assignment form.
 Research
Newton’s contributions to physics and write a onepage
summary. Do you think his three laws of motion were his
greatest accomplishments? Explain why or why not.
Use an A Layer Assignment form.

Older roller coasters rely on chain systems to pull the
coaster up the first hill, newer ones depend on hydraulic systems to do
the same job. Research each of these two systems.
What do you think are the advantages and disadvantages of using each
system? Which one should be used? Why? – Use an A
