AGENDA:1 – Quick Chem and
Discussion2 – Brain Pop3 – Cornell Notes4 – Graphic Organizer
Today’s Goal: To differentiate
between the different states of matter.
HOMEWORK: 1. Read Chapter 3.1
pages 71-75. Answer questions1-4 on page 75.
2. Make for vocab flashcards for the section.
Cornell Notes Ms. Barkume10/9
States of MatterWhat are the 3 states of matter?
What are the properties of the states of matter.
Solid, Liquid, Gas
Summary: Finish in Class
Solid Retain fixed volume; rigid particles locked into place.
Definite volume.
Not easily compressible; little free space between particles.
Definite shape.
Does not flow easily; does not expand when heated.
Particles vibrate or move slowly; does not move from place to place
Liquid Assumes shape of its container; particles slide past one another. Indefinitie volume.
Slightly compressible; some space between particles.
Indefinite shape.
Flows easily; expands some when heated.
Vibrates; particles move past one another linearly.
Gas
(Vapor)
Assumes shape of its container; particles move past one another fast.
Indefinite volume.
Easily compressible; lots of free space between particles. Indefinite shape.
Flows easily; expands a lot when heated.
Particles move fast at high speeds and no pattern to movement.

Summary (finish for homework or in class if time permits)
Percent Error
Percent Error: (Accepted Value – Measured Value) x
100 Accepted Value
Example: Accepted value = 1.2 Measured value = 1.3 (1.2 – 1.3) x 100 = 8.3 % 1.2Actual Density of H2O = 1.00 g/mL
Steps of Inquiry
Ask a QUESTION
Make a PROCEDURE
Interpret RESULTS
Make a Conclusion
Guides
Influences (data)
Using data to:
Density
Density is a physical property of matter.
Defined as the amount of mass per unit of volume.
Density = mass (grams)volume (mL)
Reading Graduated Cylinders
Graduated cylinders are used to measure volume of liquids.
How much liquid is the graduated cylinder?
Reading Graduated Cylinders
Graduated cylinders are used to measure volume of liquids (in mL).
How much liquid is the graduated cylinder? The curved line is
the meniscus. Read the volume from the bottom of the curve.
The volume of the liquid is 35 mL.
Reading Graduated Cylinders
Graduated cylinders are used to measure volume of liquids (in mL).
To read, find the lines labeled with numbers
Count the steps between Divide
10/10 =1
Every tick mark is 1mL
Reading Graduated Cylinders
Read at the meniscus10/10 =1
Every tick mark is 1mL
Volume = 35 mL
1/5 = 0.2
Every tick mark is 0.2 mLVolume
is 6.2 mL
Types of Data• Data does not equal scientific evidence• Previous knowledge + DATA = Scientific
Evidence• Qualitative Data: information that describes color,
odor, shape, or some other physical properties• Quantitative Data: Numerical information that
tells you how much, how little, how big, how tall or how fast.
• Data Tables organize data for display and understanding.

Tables5 – Wrap Up
Today’s Goal: To understand the
importance of lab safety and lab safety rules
HOMEWORK:1. Complete lab
safety worksheet
Data Table
Data Tables display data Previous knowledge + DATA = Scientific
Evidence Qualitative Data: information that
describes color, odor, shape, or some other physical properties
Quantitative Data: Numerical information that tells you how much, how little, how big, how tall or how fast.
Understanding Lab Safety
• You should NEVER try to taste any of the substances.
• You should ALWAYS wear your lab goggles. Some of the lab materials are skin, eye irritants.
• Always dispose of the laboratory materials appropriately.
• Wear appropriate clothing and shoes.• REMEMBER the class rule: FOLLOW
DIRECTIONS!
