26 Depression slide

27 Beaker  Cup-like container with graduated markings (known scientific measurements)…

28 Flask  Modified container that can be used for mixing chemicals. Can also be used for the temporary storage of chemicals.

29 Test tube:  Cylindrical glass tube used for conducting experiments.

30 Test tube rack:  Holds test tubes securely before, during, and after experiments.

31 Microscope Slide:  Thin rectangular piece of glass for a specimen to rest upon while viewing with a microscope.

32 Cover slip:  Protective cover placed upon a microscope slide to keep the viewed material stationary.

33 Depression slide:  Specialized microscope slide that has a small depression for viewing material too large for traditional slides. Also used for viewing live specimens.

34 Graduated cylinder:  Provides accurate measurements of liquids used in the lab in increments as small as 1 milliliter (ml).

35 Test Tube Brush:  Used to clean test tubes before and after each lab.

36 Safety Glasses (Goggles):  Worn to protect the eyes from flying debris and sprayed fluids during labs.

37 Eye dropper:  Allows a controlled dispensing of liquids during experiments.

38 Stirring Rod:  Thin piece of glass used in labs for stirring liquids and solids together.

39 Dissecting Tray:  Metal tray with a wax bottom upon which a specimen is explored and experimented during labs involving dissection.

40 Probe:  Blunt thin tool used during dissection that allows for separation of tissues… without causing excessive damage.

41 Dissecting Needle:  Fine-tipped probe used to maneuver parts of a dissection specimen during labs.

42 Forceps:  Also known as tweezers, used for grasping parts of a specimen during dissection.

43 Petri Dish:  A two part dish commonly used with agar for growing micro- organism cultures for study.

44 18. Microscope:  Lab equipment that uses lenses, mirrors, and light to magnify items not seen with the naked eye.

45 Compound Light Microscope:  The kind we use in class. Ours can magnify up to 400 times (400X).

46 Scanning Electron Microscope  Can magnify up to 100,000 times (100,000 X)!  Produces a 3-D image of the surface of the object.

47 Scanning Electron Microscope  Bounces electrons off the surface of the specimen.

48 Scans a 3-D image of the outside of the specimen:  Black Widow Spider claw (500X)

49 Transmission Electron Microscope  Can magnify up to 200,000 times (200,000 X) !!  Electrons pass through the specimen.  A flat image is produced that shows the specimen’s insides.

50 Transmission Electron Microscope

51 Heart muscle cells seen with a transmission electron microscope at 20,000 X.

52 19. Thermometer:  Measures temperature using the Celcius (ºC) scale.

53 20. Triple Beam Balance:  Measures mass of an object, item, or specimen using counter balances (known masses). Mass is measured in grams (g).
