2. Warm Up
List two safety rules and why they are important in the science lab.
2. What is your scicence class website address?

3. Lab Equipment

4. Beaker
Beakers hold solids or liquids that will not release gases when reacted or are unlikely to splatter if stirred or heated.

5. Goggles
Goggles or safety glasses are forms of protective eyewear that usually enclose or protect the area surrounding the eye in order to prevent particulates, water or chemicals from striking the eyes

6. Erlenmeyer Flask
Erlenmeyer flasks hold solids or liquids.

7. Triple Beam Balance Scale
A triple beam balance is an instrument used to obtain precise measurements of masses.

8. Metric Ruler
A metric ruler is used to measure the length, height and width of an object or the distance between two points, objects or places.

9. Florence Flask
it is used for the mixing of chemicals. Narrow neck prevents splash.

10. Graduated Cylinder
A graduated cylinder is used to measure volumes of liquids.

11. Test Tubes
Test tubes are used to heat, hold and mix small quantities of liquid or solid chemicals during experiments.

12. Test Tube Holder
A test tube holder is useful for holding a test tube which is too hot to handle.

13. Test Tube Brushes
Test tube brushes are used to clean test tubes and graduated cylinders.
Forcing a large brush into a small test tube will often break the tube.

14. Test Tube Racks
Test tube racks are for holding and organizing test tubes on the laboratory counter. Plastic racks may melt in contact with very hot test tubes.

15. Glass Stir Rod
A glass rod is used to manually stir solutions. It can also be used to transfer a single drop of a solution.

16. A thermometer is a device used to measure temperature.

17. Medicine Dropper
A medicine dropper is used to transfer a small volume of liquid (less than one mL).
On top of each medicine dropper is a “rubber bulb”

18. Spring Scale
A spring scale can not measure mass, only weight.

19. Forceps
Forceps (or tweezers) are used to pick up small objects.

20. Funnel
A funnel is used to aid in the transfer of liquid from one vessel to another.

21. Beaker Tongs
Beaker tongs are used to move beakers containing hot liquids

22. Bunsen Burner
Bunsen burners are used for the heating of nonvolatile liquids and solids.

23. Ringstands and their Components
Ringstands are a safe and convenient way to perform reactions that require heating using a Bunsen burner.

24. Ringstands and their Components Iron Rings
Iron rings connect to a ringstand and provide a stable, elevated platform for the reaction.

25. Ringstands and their Components Utility Clamps
Utility clamps are used to secure test tubes, distillation columns, and burets to the ringstand.

26. Ringstands and their Components Wire Gauze
Wire gauze sits on the iron ring to provide a place to stand a beaker.
On older wire gauze, the white material is asbestos!
