Lab Tools are WAY COOL!!!

RULES:

Lab tools are NOT toys! Wash them, dry them, and put them back

in their place after every lab. Report breakage to the teacher

immediately! YOU are responsible for them – don’t

blame others.

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)

Beaker Safety

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

Goggles

Used to protect your eyes from broken glass, chemicals and flames.

Clean them carefully

Make sure they fit - snuggly, but not too tightly.

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

Meter stick

Meter sticks measure length in cm 100 cm = 1 meter Don’t bend Not a weapon

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, itwill fall over easily.

Used to view small organisms or substances The cover doesn’t stay on – carry carefully Don’t use if cracked.

Petri dish

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.

Hot Plate

A tool that is used as a heat source, usually powered by electricity

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.

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.

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

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!

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.

Spring Scale

a tool that is used to measure weight (the heaviness of an object relating to gravity).

Measured in Newtons or grams.

Hand Lens

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

Funnels

It is used to funnel liquid or fine-grained substances into containers with a small opening.

Without a funnel, much spillage would occur.

BEAKER TONGS

These are used to hold a hot beaker.

THERMOMETER

Used to measure temperature

Always use Celsius in the Science lab!
