Practice / Application At each station perform the describe activity and record your observations in the Application section of your journal

Connection Use your observations from today’s activities to answer: What Makes Air Pressure Change?

Exit Summarize what you have learned about air pressure today. Please make sure that you are writing at LEAST 3-5 sentences!!

Hair Dryer – Ping Pong Ball What to Do:  Turn the hair dryer on high and point it toward the ceiling. Make sure to use a cool-air setting!  What do you think will happen if you gently place the ping pong ball into the stream of air? Will it blow away, drop to the floor or float? Try it and see.  Try walking slowly, tilting or jiggling the hair dryer. What happens to the ball?

Leaf Blower – Toilet Paper Place roll of toilet paper on broomstick, and have two volunteers hold the broom stick horizontally. Shoot the air stream from the leaf blower at the bottom of the toilet paper sending it high into the air and covering your target.

Atomizer Fill the cup nearly full of water by dipping it into the pail. Hold the cup level with one hand, and - with the fingers of the same hand - hold a half straw vertically so that its bottom end is immersed in the water and its top end is about 1.5 inches above the water’s surface. Using your other hand, hold another half straw to your lips so that you can blow through it. Hold the cup so that you can blow a stream of air perpendicular to and across the top of the immersed half-straw.
