Canvas homework due Wednesday. Lab this week: Parallax. Overview of the Universe. Solar System, Galaxy, Universe. Largest scales. Expanding Universe. Evidence for a Big Bang. Evidence for an accelerating Universe . Lesson 1. Stars. • The Sun and stars appear to move from east-to-west across the sky.. • They are not really moving. It is the rotation of the Earth that gives this illusion.. Stars. • Stars are ball-shaped masses of superheated . *ezemslaw@yahoo.com ABSTRACT kilometers. Defined in this way, the Niger Delta consists of nine states (Abia, Akwa Ibom, Bayelsa, Cross River, Delta, Edo, Imo, Ondo and Rivers) and 185 local governmen Size of the Earth (Geometry!!!!!).

If you know the distance an object travels in a certain amount of time, you can calculate the speed of the object. . Speed is a type of rate. A rate is a measurement of something that occurs or changes in one unit of time.. Scientific Notation. Power. of 10.

A person walks ½ mile each ¼ hour. How far do they walk in one hour? How long does it take them to walk one mile?. In this lesson you . will learn how to find unit rates in situations involving fractions. How are instantaneous speed and average speed different?. . Speed. Average speed is computed for the entire duration of a . trip (includes starts and stops so it slows your rate down), . and instantaneous speed is measured at a particular . 1. Ancient Astronomy.
