D-day (demo day)

Great day once again in seventh period chemistry. Three awesome demos and of course an immense amount of learning. We dove right into our notes on the properties of gases. We discussed the relationships between NUMBER OF ATOMS, PRESSURE, VOLUME, and TEMPERATURE. The Chem Think homework did a beautiful job of explaining this and so did Mr. Lieberman. The notes for Tuesday's class are slides 1-5 .

Gases pt.1

The first demo was the bed of nails demo. Liebs tricked all of us (mostly Bailey) into believing that he was some sort of crazy superhuman daredevil by lying on a bed of nails

It turns out that any average Joe can lay on this plank, because of a simple equation.

Pressure = Force/Area. Because the area is so large, the pressure is decreased and the bed of nails becomes very comfortable.

The next demo involves a vacuum, a small Japanese child, and a garbage bag. It was meant to simulate the feeling of having 15 lbs of pressure on us at all times.

The third demo involved shaving cream and more vacuums. This demo can also be done with a balloon.

Because there is almost no air outside of the balloon, it expands.

The moral of today's class is that if anyone ever asks you what you do in Chemistry, you tell them that we lie on beds of nails and put kids in bags without air.

Next scribe is Takashi, he deserves it after what he went through.
