  1. Lab Equipment

  2. Microscope: makes an enlarged image of a very small object.

  3. Graduated Cylinder: measures the volume of liquids and solids

  4. Safety Goggles: protects eyes when using heat and chemicals

  5. Beaker: holds and measures liquids.

  6. Dropper: measures out drops of a liquid

  7. Metric ruler: measures length

  8. Balance: measures mass

  9. Thermometer: used to measure temperature

  10. Anemometer • Measures wind speed

  11. Barometer • Measures air pressure

  12. Rain gauge • Measures amount of precipitation/rain

  13. The Metric System: aka SI (system international) • most commonly used system • most other countries use it • all sciences use it

  14. We will use the following units of measure: • Mass = gram (g) • Volume = liter (L) for liquids or cm3, cubic centimeter (cm3) for solids • Temperature = degrees Celsius • Time = second (s) • Length = meter (m) • Density = g/cm3; 1mL = 1cm3

  15. Length • Length: distance between 2 points • metric rulers and meter sticks are used to measure length

  16. Mass: measure of the matter in an object

  17. Density • mass per unit volume of a material • found by dividing mass by volume

  18. Time • Time: interval between 2 events

  19. Temperature • measure of how hot or cold something is • we will use Celsius • Water: Freezing= 0 degrees Celsius, Boiling = 100 degrees Celsius • ‘normal’ human body temperature = 37 degrees Celsius

  20. Volume: amount of space occupied by an object • if you can measure straight sides with standard length units, you can figure volume by multiplying the outer dimensions.

  21. volume can also be measured in liters. • BE AWARE OF THE MENISCUS!! • Meniscus: the curvature of the surface of water. • Always read water levels at the lowest point (bottom of the meniscus)
