2. The most important Lab Safety Rule…….. Always follow directions

3. Goggles Goggles should always be worn when chemicals are used, heated, or mixed.

4. Chemical Rules: If you get chemicals in your eyes or on your skin, wash for 15 minutes. Never EVER point a test tube or bottle that you are heating toward yourself or anyone else.

5. Chemical Rules: If you need to smell a chemical, hold it 6 inches away from your nose and wave or waffle the fumes toward your nose. NEVER smell chemicals directly!!!!

6. Cleanliness: Your lab area should always be clean when you start a lab and when you finish a lab. If a toxic substance was used, follow proper disposal directions given by your teacher.

7. Just say NO: Horseplay is NEVER allowed in the lab. If you are caught horse-playing you will be kicked out of the lab. Food, drinks or gum is NOT allowed to be out during a lab.

8. Dress Code: Always tie long hair back Closed-toe shoes only No loose clothing; roll baggy sleeves up tight If it dangles, it’s dangerous!!!

9. Fire: If there is a fire in the room, notify the teacher IMMEDIATELY. If the fire is on you, stop, drop, and roll. Use a fire extinguisher, by remembering PASS (Point Aim Shoot Sweep) the base of the flame.

11. Always remember: Its better to be safe than sorry Tell the teacher if any accident occurs

33. Lab Equipment

34. Beaker Used to hold measure, mix, and transport liquids Not precise for measuring

35. Bunsen Burner To heat substances

36. Cover Slip and Microscope Slide Cover Slip: To flatten the object being viewed and to keep the lens clean Microscope slide: holds the specimen

37. Dissecting Tools: Dissecting pins: to stabilize the organism Dissecting scissors: to cut the organism Dissecting tray: To hold the organism

38. Medicine Dropper: Transports or measures out small amounts of a liquid

39. Forceps: Similar to tweezers; used to grab small objects

40. Funnel: Used when pouring things from one container to another to avoid spills

41. Graduated Cylinder: Designed to make accurate volume measurements which are always read from the bottom of the curve (meniscus)

42. Read the Meniscus

43. What Graduated Cylinder Should You Use? The smaller graduated cylinder that can be used the more precise the measurement. If you had a 10 mL, a 25 mL, and a 50mL graduated cylinder, which would you use for the following: 13 mL 6 mL 47 mL 32 mL

44. Measuring Volume of Irregular Object 1 st Measure a liquid volume (19 mL) 2 nd Place object in graduated cylinder, record volume (24 mL) 3 rd (Object and liquid volume) – (Liquid volume) = volume of object

45. Magnifying Lens Magnifies small objects up to 10 times

46. Microscope Used to view very small objects at a magnification of 40 to 100 times

47. Petri Dish Flat disk with a cover used primarily to grow bacteria

48. Pipette Used to transport liquids (usually small drops)

49. Probe A pointed object used to examine organisms (used during dissection) (4F)

50. Metric Ruler or Meter Stick Used to measure length in millimeters, centimeters, and meters

51. Accuracy VS Precision Accuracy: how close the measurement is to the actual value. Precision: the exactness of a measurement broken down into the smallest possible increment *Best used in experiments because data is more likely to be repeated. *depends on the instrument used

52. Safety Goggles To protect your eyes

53. Scalpel A small blade used to cut tissues

54. Test Tube: Made of special glass; used to carry and heat chemicals When heating, hold with a test tube clamp, slant at 45°angle away from you and others Move across the flame while heating

55. Erlenmeyer Flask VS Florence Erlenmeyer flask is commonly used for storing and mixing liquids. The shape allowing good swirling to mix, with reduced chance of loss of solution. Florence flask is a boiling flask used to bring solutions to the boil. The round bottom allowed good heat distribution and the spherical shape avoided cracks due to heating/cooling stresses.

56. Test Tube Rack and Test Tube Clamp Test tube rack: designed to hold one or more test tubes Test tube clamp: holds one test tube

57. Thermometer An instrument for determining temperature

58. Celsius Thermometer Celsius is the temperature scale that is based on zero degrees being the freezing point of water and 100 degrees as being the boiling point of water.

59. Triple Beam Balance An instrument used for measuring mass

60. Measuring Mass with Containers 1 st measure the mass of the container 2 nd measure the mass of the object inside the container 3 rd (Container and object mass) – (container mass) = object mass

61. Spring Scale Spring scales measure mass. Remember, weight depends on gravity.

63. The most important Lab Safety Rule…….. Always follow directions

64. Goggles Goggles should always be worn when chemicals are used, heated, or mixed.

65. Chemical Rules: If you get chemicals in your eyes or on your skin, wash for 15 minutes. Never EVER point a test tube or bottle that you are heating toward yourself or anyone else.
