Brainstorm What is chemistry? What will you see this unit? What
will you hear discussed? What will you do this unit? Slide 2 Slide
3 Outcomes 2.1k- What are caustic materials? What are some
reactions that should be avoided? 2.4s- Demonstrate knowledge of
WHMIS standards, by using proper techniques for handling and
disposing of laboratory materials AF. Safety- Show concern for
safety in planning, carrying out and reviewing activities Slide 4
1.1 Identification of Safety Issues 1) Independently create a list
of the safety hazards that appear on the next slide. 2) When asked,
turn to your partner and share your ideas 3) Share as a whole
class. Slide 5 Slide 6 Lab Safety Mind Map Create a mind map by
adding lab safety ideas to the following topics Lab Safety
ClothingBehaviorsProcedures Prevention Slide 7 Lab Rules Using the
mind maps you created, come up with 5 rules for working safely in
the lab Share as a class Slide 8 Lab Safety Video

Safety Scenarios With your assigned group, choose one scenario
Create a skit to explain your scenario and the right and wrong way
to handle the situation Be ready to share! Slide 10 Safety Rules 1.
Read & know procedure. 2. Wash hands after lab. 3. No food or
drink in the lab no tasting! 4. Wear safety googles always. 5. Waft
substances to smell them. 6. Tie back long hair. 7. No flip-flops
or open shoes 8. Place test tubes in a test tube rack when
transporting and pouring in liquid. Slide 11 Safety Rules 9. Wipe
up spills. 10. Wipe off counter after lab. 11. Place chipped/broken
glass in broken glass pail. 12. Label ALL beakers/test tubes. 13.
Report all accidents/spills. 14. Stay at your lab bench with your
group. 15. Never leave lab bench unattended. Slide 12 PPE Personal

Symbols-examples Slide 17 Household Symbols Slide 18 WHMIS Symbols
Workplace Hazardous Materials Information System Differs from
household symbols WHMIS is worldwide! MSDS- Material Safety Data
Sheets Information about each chemical used Ex. Flammability,
volatility, mp, bp Slide 19 Slide 20 WHMIS symbols Where would you
see each of these symbols? Slide 21 Special Note: Caustic ability
to burn or corrode tissue ; refers to strong bases NaOH Corrosive
ability to corrode; mainly refers to acids HCl Corrode means to
gnaw at (Latin) Slide 22 Reactions to AVOID Bleach X ammonia =
Chlorine gas (BAD) Used as a chemical warfare agent in WWII
corrosive especially when inhaled + Slide 23 Assignment Pg. 96 qs.
3, 4, 5, 6, 7 Review as a class when finished Slide 24 1.2
Classifying Matter 1.2k -How can we classify materials based on
properties? 1.2k - How can we classify materials based on their
composition? Slide 25 Try It On a spare piece of paper How would
you group/classify the following items? *Make sure to jot down your
justification for your groups.* Slide 26 1.2 Classifying Matter
Matter any substance that occupies space and has mass Ex. Air,
Water Example of non-matter is: Skills Ideas Energy Slide 27 1.2
Classifying Matter Particle Model of Matter (review) Matter is made
of particles Particles attract each other Particles are always
moving Particles move faster with higher temperatures Each pure
substance has different particles than another substance Slide 28
1.2 Classifying Matter A. States of Matter SolidLiquidGas
MeltingEvaporation FreezingCondensation Deposition Sublimation
Slide 29 1.2 Classifying Matter Draw the particles within the
beaker to demonstrate the particle model of matter and states of
matter Solid Liquid Gas Slide 30 1.2 Classifying Matter B.
Composition Matter Mixtures Mechanical mixtures Solutions
Suspensions Colloids Pure Substances Compounds Elements Made of 1
kind of matter One kind of atom Two or more atoms/eleme nts in a
fixed proportion Combo of pure substances Looks like one substance
Particles are suspended & hard to separate Particles suspended
but can be separated Different parts are visible Slide 31 1.2
Classifying Matter Examples Matter Mixtures Mechanical mixtures
Solutions Suspensions Colloids Pure Substances Compounds Elements
Oxygen O 2 H20H20 Vinegar Grape jelly Italian salad dressing Choc
chip cookie Slide 32 1.2 Classifying Matter Heterogeneous
mixtureHomogeneous mixture Appear as two or more parts Appear as
one Mechanical mixture, suspension, colloid Solutions Slide 33 1.2
Classifying Matter Solutions can be in different states dont let
this fool you! Type of SolutionExample Solid in liquidIced Tea
sugar + water Liquid in liquidVinegar acetic acid + water Gas in
liquidPop carbon dioxide + water Gas in gasAir Oxygen + nitrogen
Solid in solidBrass copper + zinc Slide 34 1.2 Classifying Matter
C. Properties of Matter Matter can be identified and classified
based on physical and chemical properties Slide 35 Physical
property Description Lustre, color, odor, texture, Melting point o
C solid liquid Boiling point o C liquid solid Hardness Mohs scale;
ability to resist being scratched (Diamond is 10 hardest)
Malleability Ability to be pounded or rolled into sheets ex.
aluminum Ductility Ability to be stretched into long wire ex.
copper Crystal shape Salt = cube silicon = diamond shape Solubility
Ability to be dissolved ex. Oil is not soluble in water Density Oil
is less dense than water Conductivity Electrical or heat Viscosity
Rate at which a liquid flows Ex. Molasses is viscous Slide 36
Chemical Properties Reaction with acids Reaction with water
Reaction with air Ability to burn Reaction to heat Video: Chemical

LAB: Identifying Mystery Substance Turn to pg. 100-101 Pre-lab:
Title Question Outcome look on outcome sheet and write out the
outcome the lab is building on Read through procedure be ready to
answer questions before you are able to enter the lab Safety list

What evidence shows that properties of a material are changed? 1.3k
- How do you know if a new substance has been made? Try IT: Turn to
pg. 105 Skill Practice Slide 41 1.3 Changes in Matter Physical
ChangeChemical Change Composition stays the same Formation of a new
substance with new physical properties Evidence: -State changes
-Dissolves Evidence: -change in color -change in odor -formation of
solid or gas -release or absorption of energy (cool or hot) Ex. Ice
cream meltingEx. Propane burning (combustion) Slide 42 Practice:
Label each of the following as either a Physical (P) or Chemical (
C) change SubstanceP or C Ice cubes melting Burning a candle
