1. Turn in Flint Safety contract and parent form and pick up papers from front 2. Draw me a picture/cartoon of what NOT to do in lab!
Lab Safety!!!
What rules does Ms. Johnson think are important? Obey instructions the first time they are given. No unauthorized experiments! Always wear safety equipment. Dress appropriately for lab. Only use what you need. Dispose of chemicals only according to directions. Dispose of broken glassware only in the designated place. Hold test tubes appropriately when being heated. Hot glass looks exactly the same as cold glass. Waft to detect chemical vapors. The first thing to do in emergency drills is turn everything off.

Matter is anything that has mass & takes up space (solids, liquids, gases, plasmas)
States of Matter
Classification of Matter
SOLUTIONS COLLOIDS SUSPENSIONS
Pure Substance: Made up of only ONE thing & has a CONSTANT COMPOSITION Element: Made up of ONE atom (one element from the periodic table!) Cannot be broken down any further EX: Carbon (C), Nitrogen (N), Oxygen(O), Sodium (Na) Compound: TWO or more atoms chemically combined (molecule) Can be chemically broken down into individual atoms Definite ratio of elements in the compound EX: Water (H2O), Salt (NaCl), sugar (C6H12O6)
Mixture: Made up of TWO or more substances (amount of each substance doesn’t matter) that can be physically separated Homogeneous: Substances are mixed EVENLY throughout Looks the “same” EX: Sugar Water, Salt Water, Kool-aid Heterogeneous: Substances are NOT evenly distributed Looks “different” throughout EX: Concrete, Dirt, Pond Water
