Laboratory Equipment Notes
Test tube or bottle brush
Triple beam balance
To find out how tall you are in inches, multiply by.3937 inches per centimeter.
Test Tubes and tongs
Test tube Rack
Probes Bent probe Needle probe
Beaker Cup-like container with graduated markings (known scientific measurements)…
Flask Modified container that can be used for mixing chemicals. Can also be used for the temporary storage of chemicals.
Test tube: Cylindrical glass tube used for conducting experiments.
Test tube rack: Holds test tubes securely before, during, and after experiments.
Microscope Slide: Thin rectangular piece of glass for a specimen to rest upon while viewing with a microscope.
Cover slip: Protective cover placed upon a microscope slide to keep the viewed material stationary.
Depression slide: Specialized microscope slide that has a small depression for viewing material too large for traditional slides. Also used for viewing live specimens.
Graduated cylinder: Provides accurate measurements of liquids used in the lab in increments as small as 1 milliliter (ml).
Test Tube Brush: Used to clean test tubes before and after each lab.
Safety Glasses (Goggles): Worn to protect the eyes from flying debris and sprayed fluids during labs.
Eye dropper: Allows a controlled dispensing of liquids during experiments.
Stirring Rod: Thin piece of glass used in labs for stirring liquids and solids together.
Dissecting Tray: Metal tray with a wax bottom upon which a specimen is explored and experimented during labs involving dissection.
Probe: Blunt thin tool used during dissection that allows for separation of tissues… without causing excessive damage.
Dissecting Needle: Fine-tipped probe used to maneuver parts of a dissection specimen during labs.
Forceps: Also known as tweezers, used for grasping parts of a specimen during dissection.
Petri Dish: A two part dish commonly used with agar for growing micro- organism cultures for study.
18. Microscope: Lab equipment that uses lenses, mirrors, and light to magnify items not seen with the naked eye.
Compound Light Microscope: The kind we use in class. Ours can magnify up to 400 times (400X).
Scanning Electron Microscope Can magnify up to 100,000 times (100,000 X)! Produces a 3-D image of the surface of the object.
Scanning Electron Microscope Bounces electrons off the surface of the specimen.
Scans a 3-D image of the outside of the specimen: Black Widow Spider claw (500X)
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.
Transmission Electron Microscope
Heart muscle cells seen with a transmission electron microscope at 20,000 X.
19. Thermometer: Measures temperature using the Celcius (ºC) scale.
20. Triple Beam Balance: Measures mass of an object, item, or specimen using counter balances (known masses). Mass is measured in grams (g).
Biology AHSGE Standard I- Appropriate Laboratory Materials.
Science AHSGE Standard I-1, part 2- Appropriate Laboratory Materials.
Lab Equipment. Balance Digital Digital Triple beam Triple beam Measures mass Measures mass Unit is a gram Unit is a gram.
Lab Equipment Science equipment Name: Petri Dish Job: shallow dish used for cultures.
Warm –up: What is the density of the block? CUBE DESCRIPTION Material Plastic Length of each side 2 cm Mass 24 grams Weight 6.6 N.
Tour of the Lab and Lab Equipment General Chemistry Galax High School Mrs. Parris.
Lab Equipment. Familiarize yourself with the following: 1. Know the names of the individual pieces of lab equipment. 2. Know the use of each piece. Note:
Lab Equipment. Beaker Beakers hold solids or liquids that are unlikely to splatter if heated or stirred. Measures Volume.
Lab Safety Rules & Procedures 1.No food/drink in the lab area. All you need in lab area: lab instructions, notebook & pen. 2. Safety glasses required for.
Using Metric Tools. 1. Ruler The ruler above has an English side that uses inches and a metric side that uses centimeters. We will only use the metric.
Light Microscopes Use lenses to direct light in order to enlarge images.
Measurement & Scientific Tools. Biblical Reference He measured its wall and it was 144 cubits thick, by man's measurement, which the angel was using.

Chapter 3 Notes, part 1 Looking at Cells Cells were discovered in the 17 th century, when microscopes were invented….
Science Vocabulary. Write this definition in your science folder Cooperate To work together with others to reach a goal.
Measuring Volume Temperature Mass. Reading the Meniscus Always read volume from the bottom of the meniscus. The meniscus is the curved surface of a liquid.
When using hazardous chemicals, always wear an apron, goggles, and gloves. TRUE.
