Well, I am going to teach you many new games.I intend to instruct you in a science full of interest, wonder, and
beautya science that will afford you amusement in your youth, and riches in your more mature years. In short, I am going to teach you the science ofIf I were to present myself before you with an offer to teach you some new game—If I were to tell you an improved plan of throwing a ball, of flying a kite, or of playing leapfrog, Oh, with what attention you would listen to me!

The tactile component of the observation can only be experience by doing!!!Trap air inside a syringe. Observe as you increase and decrease the pressure.
What’s the evidence that the pressure inside has increased?Slide29
From phenomena to student generated models…Put a small, tied-off balloon into the syringe. Close the system. What happens if you decrease the pressure in the syringe?
Repeat the experiment with a marshmallow. What happens?Slide30
