Rockets: Educators Guide
provides lessons, activities, and information on basic rocket science and rocket history. Lessons include making and flying paper rockets, investigating ways to increase the power of rocket fuels, estimating the altitude a rocket achieves during flight, and demonstrating how rocket liftoff is an application of Newton's Laws of Motion. Emphasis is on hands-on science, prediction, data collection and interpretation, teamwork, and problem solving. (National Aeronautics and Space Administration)

Interesting Fact:
To enable a rocket to climb into low earth orbit, it is necessary to achieve a speed, in excess of 28,000km per hour. A speed of over 40,250 km per hour, called escape velocity, enables a rocket to leave earth and travel out into deep space. Attaining space flight speeds requires the rocket engine to achieve the greatest action force possible in the shortest time. |
