The Physics of Air Pressure

How do these demonstrations work?

 

All of these experiments run on the same principle. That principle is to lowering the pressure in one system to create a desired effect. There are a few ways in which  a pressure change can happen. The three ways I discussed in my presentation were, changing the volume of the container, changing the temperature of the container, and changing the amount of air inside the container. The Straw race involves changing the volume, the plate suction experiment involves changing the amount of air, Crushing the pop can, Create your own fountain, and fitting an egg into a milk, all involve changing the amount of air in the container as well. This is accomplished through heat. 

 

Some interesting topics to discuss during your lecture.

Below are a few topics I chose to discuss during my presentations. If you have any other ideas, or would like clarification on any of these topics, feel free to contact me.

• The effect of air pressure on weather

• How air pressure helps pump water

• Air breaks and car tires

• Balloons and straws

There are many topics to discuss, this is not an extensive list!
