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.

States of matter

• Solid- matter that can not flow and has definite volume.

• Liquid- definite volume but takes the shape of its container (flows).

• Gas- a substance without definite volume or shape and can flow.

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

Notebooks

• Why notebooks?• What goes in notebooks?• How are they set up?

– Title Page– Number your Pages– Glue the corners only

• How often do you bring your notebook?• How are they graded?

Types of Matter & Classification of Matter

• Notebook Add-Ons:– Title Page (Name, Period, Drawings/Pictures about yourself)– Next 2 pages: glue in Table of Contents– P. 1: “Unit 1 Organizer/Key Terms”– P. 2: “Unit 1 Proficiency Tracker”– P. 3: “Investigating Changes Lab/Notes”– P. 4: “MSDS/NFPA Activity”– P. 5: “States of Matter/Classification of Matter Notes”

• Homework!– REALLY get your supplies this time! Notebook check next class! (for a

grade!)– Study for Quiz #1 (Scientific Investigations, Physical/Chemical Changes, Lab

Safety, States of Matter, Classification of Matter)

Exit Ticket
