A layer Assignment

1. 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.
2. 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.
3. 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.
4. Research Newton’s contributions to physics and write a one-page summary.  Do you think his three laws of motion were his greatest accomplishments?  Explain why or why not.  Use an A Layer Assignment form.
5. 3.  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 Layer Assignment form.
