Lab Tools are WAY COOL!!!

1. Lab Tools are WAY COOL!!!

2. 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.

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 • Don’t 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 doesn’t stay on – carry carefully • Don’t use if cracked.

10. Pipettes and droppers • The DROPPER PIPETTE is a medicine dropper and dispenses small drops of liquid. • Some have units. • 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.

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!
