Rockets 01 OPENING QUESTION:  How is it that a rocket can fly in space but an airplane cannot? LEARNING GOAL FOR TODAY: I will be able to show how a rocket can work in outer space after today's class WORDS O' THE DAY: Newton's 3rd Law: For every force exerted on an object, there is a separate but equal and opposite force exerted on a second object. WORK O' THE DAY: Rockets seem to be deceptively simple: Fuel is ignited and the rocket *should* move upward. Why is it, then, that rockets are so difficult to construct AND maneuver. ═══════════════════════════ Before we begin, let's do a review of rocketry for the last 100 years. Group #1: 1940 - 1945 (WWII) Group #2: 1945 - 1960 Group # 3: 1961 - 1975 (The Apollo Years) Group #4: 1975 - 2010 (The Space Shuttle) Group #5: 2010 - Present (Commercial Space Flight) Please work with your group to make a group presentation on rocketry during that period. Make sure to highlight innovations and new designs that happened during your period. Show a picture of a rocket developed during that time period How far did that rocket fly? What kind of fuel did it use? Were there significant problems with that rocket? Interesting tidbits? Let's present! Here's another interesting question -- What is the most powerful machine ever created by human beings?         ═══════════════════════════ Ladies and gentlemen, I give you the Saturn V ("Saturn Five") rocket:   The Saturn V could lift 140,000 kg into "Low Earth Orbit" or it could lift 48,600 kg to the moon! Let's work at making some observations of this image-- take a look at your handouts How much of the Saturn V rocket was used ONLY to get out of the Earth's atmosphere? Let's take a look...
