 Stand Up, Pair Up, Share
Warm Up
 A balance and a graduated cylinder are used to
determine the density of a mineral sample. The sample
has a mass of 14.7 g and a volume of 2.2 cm3. What is
the density of the mineral sample?
A. 0.15 g/cm3
B. 32 g/cm3
C. 13 g/cm3
D. 6.7 g/cm3
Use your phone as a calculator
Density = mass/volume
Using Emergency Safety Equipment
 Fire Extinguisher
 Remember the acronym PASS PULL, AIM, SQUEEZE, and SWEEP.
 Step 1- PULL the pin on the handle.
This will allow the handle to work.
Stand 8’ to 10’ from the fire.
 Step 2- AIM the nozzle at the base
of the fire. Hit the fuel. It will not do
any good to aim at the flame tops
because the chemical from the
extinguisher will pass right through
them.
 Step 3- SQUEEZE the top lever or
handle. This will allow you to release
the contents of the extinguisher.
 Step 4- SWEEP the nozzle from side
to side

Using Emergency Safety Equipment
 Fire Blanket
 Step 1- Remove fire blanket from its
container.
 Step 2- Shield your face, arms and
hands with the blanket by wrapping the
outside of the blanket around your
arms.
 Step 3- PLACE, do not throw, the fire
blanket on the burning material. No air
should be getting to the flames.
 Step 4- If it is safe, turn off the heat
source causing the fire.
 Step 5- Leave the blanket on the
burning material at least 30 minutes.
Do not remove the blanket until it is
cool.
 Note: If you are smothering a clothing
fire you should tightly wrap the blanket
around the person whose clothes are
burning and roll that person on the
floor in the blanket.
Using Emergency Safety Equipment
 Face/Eyewash
 Step 1- Guide injured student to
the eyewash station. Because
the first few seconds after
exposure to a chemical are
critical, eyewash/face wash must
be within 10 or fewer seconds of
anywhere in the room.
 Step 2- Use your hands to hold
the eyes open while using the
eyewash to be sure water
reaches the eyes.
 Step 3- Flush skin or eyes with
tepid water (60- 90 F) for at
least 15 minutes.
 DONOT RUB!
 Step 4- Get medical assistance
immediately.
Are everyday substances and
chemicals dangerous?

Science Safety
 Think about the Lab rule
 What are some lab rules?
 With your table group you will act out a lab rule or
procedure that is either safe or unsafe.
 Group Roles
1. Reader- reads the scenario
2. Actor- acts out the scenario being read
3. Props- Provides objects the actor can use to portray the
objects being read in the scenario
4. Actor/Props- Does which ever role is needed
 The class will then take a vote to decide what is rule is
and if it is safe or unsafe.
 If it is unsafe the class will explain what they should do in
the unsafe situation and how to have made the scenario
safe in the first place
Vote
 Safe
Unsafe
Homework
 On a piece of computer paper make a cartoon giving an
example of how to act safely in a science classroom and
how to act unsafely in a science classroom.


-the cartoon must have a minimum of four colors
-there must be at least one sentence describing
the scenario on each box

-label the science safety equipment

-drawings must show effort
Warm Up
The pickup truck has a changing velocity
because the pickup truck —
A can accelerate faster than the other two vehicles
B is traveling in the opposite direction from the other
two vehicles
C is traveling on a curve in the road
D needs a large amount of force to move
Velocity = Speed + Direction
Force = Mass X Accleration

With your group and on the white board write a 6
sentence explaintion describing how you would use
these objects to heat the contents of a test tube.
Briefly describe how you would use
these objects to heat the contents of
a test tube.
First, put on safety goggles and lab apron. Tie
back long hair and check your shirt sleeves.
Second, light alcohol burner with match.
Third, remove test tube from rack and hold test
tube with test tube clamp.
Finally, when heating test tube, hold with clamp,
place bottom of test tube over flame, and point
the opening away from your face.
Triple Beam Balance
Can you figure out how to make the
balance even?
If 2 diamonds = 1 circle and
2 squares = 3 circles, what do you need to
balance out 1 square?

Why is measurement important?
 Use it in daily life
 Cooking
 Construction
 Decorating a room
 Driving
 Communication
 Need to be able to communicate measurements and distances to other
people
Measurement & Physics
 Physicists try to find relationships between the quantities they measure 
use units of measurement to do this
 Measure the very largest and smallest things in the universe
 Smallest: mass of an electron
 Largest: light years (distances between stars and galaxies)
How to use a ruler
1.
Determine if you are measuring in centimeters or inches
and find that unit’s side of the ruler.
2.
Place the “0” mark at one end of the object you are
measuring.
 Each dash after a whole inch is 1/16 of an inch
 Each dash after a whole centimeter is 1/10 of an inch
