4. ESSENTIAL QUESTION Why do Astronauts feel weightless in space?

5. CONCEPTS Students will learn the following concepts: The Space Shuttles stays in orbit because of gravity; it is actually falling around the Earth. Astronauts are falling at the same rate as the Space Shuttle, giving them the feeling and appearance of weightlessness.

6. OBJECTIVES Construct a Space Shuttle Model Predict what happens to a space shuttle and its contents when they are in a state of free fall. Explore the effect of free fall on the model shuttle and on an astronaut inside the shuttle.

7. THINK ABOUT IT! On your paper, describe what happens on Earth when a ball is thrown horizontally. You can draw a picture if you need. What will happen if the ball is thrown harder?

8. QUESTION What is it called when one object revolves around another in space like a satellite going around Earth? Answer: an orbit When your throw a ball or any object, what are you really seeing before the ball hits the ground? Answer: a piece of an orbit

9. IMAGINE Now imagine that the ball could be thrown horizontally so hard that it would go around the Earth and return to you, what are you really seeing? Answer: the ball would fall around the Earth, it would be in orbit. Is the ball still falling? Answer: yes, the ball is falling around the Earth

10. COMPARE Now compare the ball to the Space Shuttle, if the ball is falling around the Earth, what is the Space Shuttle doing? Answer: it too is falling around the Earth
