Bethany Samantha Arlinda Rebecca


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.
