Pressure+Lesson+Experiments

Today we are going to talk about air pressure, after the lesson and video we'll talk about the experiments where going to do tomorrow.

If you wave your hand in the air, what do you feel?

Air pressure is all around us.

Air pressure is the pressure applied by the atomosphere.



Air pressure is high at sea level.

The closer we are to Earth's surface, the higher the air pressure is and decreases the higher up in the atmosphere you go.

(look at picture with students. Show that the cat is under multiple blankets and the dog is under 1 blanket, then go over sentences with students and write in "lots" and "few")

Ask class, "who can tell me where air pressure is highest?"

Next time we meet we'll do 4 different experiments!! Can we get the water to drain from one container to another by placing it higher?



Can we submerged this cup under water and still keep the paper towel dry?



Will the air pressure outside of the cup keep the water from spilling?



Is it possible to chop a ruler in half with it only being held down by a single sheet of newspaper?
