... b. (Model Rocket Flight) Ask the students if they have ever seen a rocket take off. Ask the students what happens during the flight of a rocket from the point that it takes off to the point that it returns to the ground. Discuss the different phases of a rocket flight: liftoff, ascent, maximum heigh ...
