Introduction to Chemistry I
• Take out a pen or pencil
and notebook.
• Your phone should be in
your bag!
• What materials will I need?
• What are the rules and
expectations?
Materials
• Three ring binder or
notebook
• Calculator
• Pen and/or pencil
• Username and
password MEMORIZED
Classroom Rules:
• No food…..ever.
• Only water in a bottle with a
lid.
• If I see your phone, I take your
phone.
• Once you’re in the room, you
stay in the room.
• Backpacks remain under your
desk for the entire block.
Be responsible.
Be prepared to work.
Participate.
Grading
•
Homework (~10%)
– Completion grade
– Late works will earn 50% of assigned value
•
Classwork and Labs (~40%)
– Should be your own work. Simply copying will not earn you any
credit.
•
Projects, Tests and Quizzes (~40%)
– Periodic quizzes, Tests or Projects at the end of a unit
– Each day a project is late 10% deduction in grade.
•
Daily Participation (~10%): The following are behaviors that will
help you earn participation points:
-Following instructions and on task behavior
-Answering and asking questions in both small groups and as a
class.
Review of Matter
• Matter is anything that
has mass and volume.
– Mass is a measure of an
object’s resistance to
change in motion.
– Volume is the amount of
space an object takes up.
Notes: Physical Properties of Matter
• Physical properties can be observed or
measured without changing the composition
of matter.
• Physical properties are used to observe and
describe matter.
Notes: Examples of Physical Properties

• Volume
• Color
• Texture
• Odor
• Density

Notes: Density
• Density: The amount of matter
in a certain amount of space.
• To measure density:
– Measure mass.
– Measure volume
• V=lxwxh=
• Units = cm3
• In order to calculate the
density:
– Density = mass / volume
– Units = g/cm 3
Lab: Density Calculation
• Density: The amount of matter
in a certain amount of space.
• In this lab:
– Choose several blocks.
– Measure mass.
– Measure volume
• V=lxwxh=
• Units = cm3
• In order to calculate the
density:
– Density = mass / volume
– Units = g/cm 3
