 * Does knowing how to use a scale on a map help you understand how to use scale to measure distances in the universe? How are they similar? How are they different?
 * Yes because we already understood how to use a scale on a map so that helped us understand the scale for the universe. The two scales are similar because they both use a smaller measurement to equal larger measurements. The two scales are different because the universal scale covers much larger distance than the scale on a map.
 * Vast distances in space are often measured in light-years. A light-year is the distance that light travels in one year, or about 6 trillion miles. Altair, a star in the constellation Aquila, is 16.6 light-years away, which means that the light we see now from that star left its surface 16 years and 219 days ago. Describe what was happening in the world when the light we are seeing from Altair first left that star. How far away is Altair in miles?
 * 16 years ago I was not born but my parents were married and the star's light was on its way to earth. 99.6 trillion mi;es is how far altair is away.
 * Explain why it would be impossible for scientists to measure stellar distances that are accurate to within a few feet. Why is it not critical to attain such accuracy when dealing with astronomical distances?
 * It is critical to attain accuracy because the distances are much larger and any mistake can send someone to somewhere else.


 * Essential Question: How do you apply Newton’s laws to describe motion? **

1. How do you describe different gravity environments? 2. What are the characteristics of projectile motion? 3. How are elliptical orbitals maintained? 4. What were some significant contributions Isaac Newton made to the description of motion?
