I know that 80s don't seem like a very high grade, but if you got an 80 on a pretest, that's actually super good. Getting an 80 on a pretest means that you already know 80% of what you're going to learn in the unit. That's really cool! It means that you already have a lot of prior knowledge!
We started exploring atoms, elements and compounds as well - we began to talk about how they're related and how they're different. I learned that atoms make up all matter. They're classified into elements, and they're counted as similar when they have the same atomic number. Compounds are substances made of two or more elements.

Mr. Ferriter also taught us that the atoms in solids are packed tightly together and vibrate. The atoms in liquids slide past each other and are less dense. Finally, the atoms in gases move unpredictably and quickly through the air.
I wonder if atoms also affect the way substances look. I know they affect the way that compounds feel because they'll be either solids, liquids or gases. But do the atoms affect their color or texture as well?
To answer my question, I'm going to pay special attention to these properties during this unit.
