Class- January 6th 2010

Hey everyone,
Today we talked about many things including particles, your science presentations which were due on the 18th, and fluids.

Starting with the science presentations, they will not be counted late until friday so please hand it in. Remember every day after the due date will have 10% taken off of it.

Particles! Today we talked about the particle theory which is below:

1. Matter is made up of tiny particles.
2.These particles are constantly moving.
3.Particles and Matter are held together by a very strong electric force.
4.There are empty spaces between the particles and matter that are very large when compared to the particles themselves.
5.Each substance has unique particles that are different from other particles and substances.
6.Temperature effects the speed of particles. The higher the temperature the higher the speed of the particles.

Remember all pure substances are homogenous.
Imagine a labradoodle (Labrador, and Poodle) this breed of dog would technically speaking be heterogeneous because the animal is made up of two different substances, whereas a purebred golden retriever is homogenous because it is made up of the same substances.

Ok, gold for example is a pure substance because it is built up of the same particles.
Gold in the periodic table is AU, it is easier for most people to remember Amazingly Unique, because those two words might help you remember the term AU, and gold is unique.
