  1. Only copy the slides that have this background  (spiral notebook)

  2. MetricSystemPart 3Volume

  3. What is Volume ? • Volume is a measure of how much space something takes up

  4. 3 Methods of Measuring Volume

  5. Method # 1: • Measure the volume of a liquid directly using glassware

  6. Meniscus Definition: the curved surface of liquid in a container

  7. Practice: 53 mL

  8. Practice: 11.5 mL

  9. Practice: 6.6 mL

  10. Method # 2: • Calculate the volume of a regularly shaped solid using geometry

  11. Geometric Formulas: • Volume of a cube is …. l x w x h i.e. 4cm x 5cm x 2cm = 40cm3 • Volume of a cylinder is ….  r2 h i.e.  x (5cm)2 x 10cm = 785cm3

  12. NOTE: Volume can be measured in: liters (L), milliliters (mL), etc. OR… cubic meters (m3) cubic centimeters (cm3), etc.

  13. Remember this slide? Benefits of the Metric System: • It uses the decimal system (10’s!) • It is an International Standard. • The units relate to each other.* • *(More on this later!)

  14. The units relate…. 1 cm3 = 1 mL using water as a standard: 1 mL H2O = 1 cm3 H2O = 1 g H2O

  15. Typically, …and cm3 or m3 are used to describe the volume of a regularly shaped solid. mL or L are used to describe the volume of a liquid...

  16. Method # 3: Calculate the volume of an irregularly shaped solid using water displacement

  17. Use water displacement to find the volume of objects with weird shapes:

  18. Use Water Displacement to find the volume of an irregularly shaped solid, such as a rock: 32 ml 22 ml - ----------- 10 ml 32 ml 22 ml

  19. A formula for water displacement:V = Vf - Vi Volume of Object = (Final Volume) - (Initial Volume)
