We're watching pressure suck the egg down into the bottle.


The fire is what took the oxygen out of the air and changed the pressure in the bottle.


The air pressure keeps the water in our cups from spilling everywhere.


The pressure kept all the water in the cup!


Trying to get our cups to work.

Students... under pressure.

Will the egg fit into the jar? How will it get there?
I bet you can't pull that bag out! Can you??? We shall see.

We filled a cup half full with water, put an index card over the rim of the cup and flipped it upside down. The higher pressure was pushing up on the card allowing the card to stay on the cup and keeping water inside cup.


Trying to get the bag out of the jar but the high pressure outside of the jar keeps the bag from coming out of the jar.



An egg sits on top of the bottle. The matches are lit!




The fire burns up oxygen inside the bottle. The lower air pressure created causes the egg to fall!



Blowing in between two pieces of paper creates lower pressure between the papers making them touch each other.




Trying to pull a bag out of a jar that has lower pressure inside of it is really hard.

We are experiencing an air pressure. This is where we filled cups half way up with water and placed an index card over the top and flipped the cup over!!!
Our three teachers; Claire, Stephanie, and Amelia are teaching us about air pressure. The activity required us to blow on sheets of paper the same length to see which direction the air pressure moves the paper.

This is an example of what our teachers are teaching above. The air pressure is moving the papers inward.

Here is Samantha experimenting and learning about how the air pressure is causing the sheets of paper to move inward.

The flame will allow the egg to fall through the bottle. (without the fire the egg is too big to fit through).

Here we can see the flame is allowing the egg to fall through, the air pressure from the outside is pushing the egg down into the glass.

Here is the egg experiment before the air pressure starts to effect it. Once Stephanie lets go of the egg, the air pressure is at work!














There is more pressure pushing on the outside of the card rather than the the inside of the card! The air pressure is keeping the card in place so the water does not spill out.

Once the match took up all the oxygen in the glass container the egg was pushed in by the air pressure outside the glass bottle. To get it out you would need to blow into the bottle to change the air pressure.

This showed that the egg was bigger than the container and needed help getting into the container. The match was still lit and since it was only 1 match it took a while to push the egg in.

For this experiment we tried to fit an egg inside a glass container that had a smaller opening than the egg. This is the first step of lighting a match and putting it into the container underneath the egg.

For this experiment we put water in the cup and tried to capture it with the piece of paper. It worked because the air pressure created a suction to the paper.

Elissa is blowing in between 2 pieces of paper. When this happens, the pieces of paper stick together instead of blowing apart.




Elissa is trying to pull the bag out of the container but can't because of air pressure. When we stuck our hands in the container we could feel like pressure inside.
