  1. Measuring Volume: Outline I. Volume a. Definition: the amount of space an object takes up (or occupies) • Volume of Liquids • a. Equipment Used: • b. Unit of Measurement: graduated cylinder, beaker liter (L) milliliter (mL) Packet p. 10

  2. Volume of Regular Solids • a. Formula: • b. Label: • c. 1 cm3 = V = L x W x H cm3 1 mL • Volume of Irregular Solids • a. Method Used: water displacement Packet p. 10

  3. Measuring Volume of Liquids Definition: the amount of space an object takes up (or occupies) Instruments used: graduated cylinder beaker Metric unit of measurement: liter L

  4. The graduated cylinder is marked off in equal units of volume. The volume of the liquid Is 7 mL.

  8. Irregularly shaped Measuring Volume of a Solid: Method used: water displacement graduated cylinder Materials needed: Metric unit of measurement: cm3 Booklet

  9. Water Displacement Method Step 1: Add water to a graduated cylinder and record the amount. Step 2: Place the object into the graduated cylinder. Step 3: Record the volume of the water with the object. Step 4: Find the difference in water volume by subtracting. Step 5: Convert the liquid volume measurement (mL) to the measurement for solid volume (cm3). *** Remember: 1 mL = 1 cm3 A B

  10. Example #1 Volume of water in graduated cylinder A = 200 mL Volume of water in graduated cylinder B = 270 mL Difference in water: 270 mL - 200 mL = 70 mL Volume of rock: 70 mL = 70 cm3 A B

  11. Volume of water without object: Volume of water with object: Difference in water volume: _____ Volume of object _____ mL = _____ cm3 32 mL 38 mL 38 mL 32 mL 6 mL 6 6 Volume of water without object: Volume of water with object: Difference in water volume: _____ Volume of object _____ mL = _____ cm3 32 mL 44 mL 44 mL 32 mL 12 mL 12 12

  12. Volume of water without object: Volume of water with object: Difference in water volume: _____ Volume of object _____ mL = _____ cm3 65 mL 69 mL 69 mL 65 mL 4 mL 4 4 Volume of water without object: Volume of water with object: Difference in water volume: _____ Volume of object _____ mL = _____ cm3 46 mL 54 mL 54 mL 46 mL 8 mL 8 8

  13. 50 mL Volume of water without object: _____ Volume of water with object: _____ Difference in water volume: _____ Volume of object _____ mL = _____ cm3 52 mL 52 mL 50 mL 2 mL 2 2

  14. volume – the amount of space an object takes up liquids are measured in mL or l graduated cylinders and beakers are used to measure liquids volume solids are measured in cm3 V = L x W x H - regular-shaped solid water displacement method - irregular-shaped solids
