Today in Chemistry Mrs. M had us go into the math lab and read the scribe post. When in the math labe we worked on signing into Chemthink, if you have not done so already. After creating a profile or singing into Chemthink Mrs. M had us read and take notes on a tutorial on atoms, molecules, compounds, and other basic units. We also learned the molecular and atomic structure of solids, liquids, and gas in the tutorial. To find this tutorial go on Chemthink, sign in, and on the left hand side there will be a box saying Tutorial. This tutorial is very, very helpful expecially when Mrs. M told us to take a ten question quiz, and if you get more than three wrong then you have to start over, which is also found on Chemthink. Despite it sounding very easy, in reality it was more than difficult for most people and they had to take the test many times. There is no limit on how many times you can take the test but if you keep failing she encouraged us to re-read the tutorial.
Atom: Most basic unit of matter
Molecule: A group fo atoms held by a chemical bond
Element: A substance made out of one type of atom
Compound: Two different types of atoms present in the same molecule
Solid: Atoms vibrate but are not free moving
Liquid:Atoms are free floating and are close together.
Gas: Very fast free flating atoms
