  • Report breakage to the teacher immediately!
  • YOU are responsible for them dont blame others.

3
Beakers
  • Containers that are used to measure and pour
    liquids, usually made of glass and can be heated
  • They don't measure the volume of liquids very
    accurately. It is usually used as a container for
    mixing or holding chemicals.
  • Measures in milliliters (mL)

4
Beaker Safety
  • Glass wear goggles
  • Use beaker tongs if hot
  • Carry with BOTH hands (one under and one around)

5
Goggles
  • Used to protect your eyes from broken glass,
    chemicals and flames.
  • Clean them carefully
  • Make sure they fit - snuggly, but not too tightly.

6
Test tubes and holders
  • Used to hold and mix small amounts of substances.
  • A TEST TUBE is used as a container to hold
    chemicals during heating or other reactions
  • TEST TUBE RACK supports the test tubes.
  • Glass and chemicals wear goggles.
  • Use tongs could be very hot or very cold

7
Meter stick
  • Meter sticks measure length in cm
  • 100 cm 1 meter
  • Dont bend
  • Not a weapon

8
Graduated cylinders
  • Used to make accurate measurements of liquid
    volumes mL.
  • Get at eye-level with liquid.
  • Measure the Meniscus read the bottom of the
    curve
  • If glass wear goggles, it
  • will fall over easily.

9
Petri dish
  • Used to view small organisms or substances
  • The cover doesnt stay on carry carefully
  • Dont use if cracked.

10
Pipettes and droppers
  • Draw a liquid into a pipette and allow the liquid
    to drain from the pipette in a controlled manner
    - drops.
  • Pipetting is used to quantitatively transfer a
    liquid from one container to another.
  • The DROPPER PIPETTE is a medicine dropper and
    dispenses small drops of liquid.
  • Some have units.

11
Hot Plate
  • A tool that is used as a heat source, usually
    powered by electricity

12
Triple Beam Balance
  • A tool that is used to measure mass (the amount
    of matter) usually in grams.
  • This is a close up of the numbers on the balance.

13
Microscope
  • A tool that is used to view very small objects by
    making them appear larger.
  • This tool magnifies the object using lenses and a
    light source.

14
Microscope Safety
  • Carry with BOTH hands!
  • Clean lenses Very carefully!
  • Coarse focus with low power ONLY
  • (1st) Low power (2nd) medium power (LAST) high
    power
  • Cover when finished

15
Slides and cover slips
  • Slides put small single layer specimens on
    these to view under the microscope.
  • Cover Slip used to cover the specimen on the
    slide.
  • GLASS do not use if scratched or broken!

16
Erlenmeyer flask
  • This is a container which gives only approximate
    measurements of volume is usually used as a
    mixing vessel or a container for heating.

17
Spring Scale
  • a tool that is used to measure weight (the
    heaviness of an object relating to gravity).
  • Measured in Newtons or grams.

18
Hand Lens
  • a tool that is used to observe objects and
    magnify them so that you can get a closer view.

19
Funnels
  • It is used to funnel liquid or fine-grained
    substances into containers with a small opening.
  • Without a funnel, much spillage would occur.

20
BEAKER TONGS
  • These are used to hold a hot beaker.

21
THERMOMETER
  • Used to measure temperature
  • Always use Celsius in the Science lab!
