3. Volume Definition:_____________________________ Definition:_____________________________ Tools: Measuring a regular solid: ________________; ____________ Tools: Measuring a regular solid: ________________; ____________ Measuring liquids or irregular solids: Measuring liquids or irregular solids: __________; ____________________ __________; ____________________ Always read the _________ of the meniscus. Always read the _________ of the meniscus. Units: _____; _____; _____; _____ Units: _____; _____; _____; _____ Basic Conversions: 1 cm 3 = _____ mL Basic Conversions: 1 cm 3 = _____ mL 1 L = _____ mL = _____ cm 3 amount of space an object takes up meter stickruler beaker graduated cylinder cm 3 m 3 L mL 1 1000 bottom

4. Method 1: Length x Width x Height Measure the ______________________ of an object and ____________ them together Measure the ______________________ of an object and ____________ them together Example: volume of a kleenex box Length = 22.5 cm; Width = 12.0 cm; Height = 7.6 cm Length = 22.5 cm; Width = 12.0 cm; Height = 7.6 cm Volume = ___________________ = ________ Volume = ___________________ = ________ multiply 22.5 cm x 12.0 cm x 7.6 cm 2052 cm 3 length, width and height

5. Method 2: Water Displacement Add enough water to a beaker or graduated cylinder to ________________________ ________ and record the level of the ___________________ Add enough water to a beaker or graduated cylinder to ________________________ ________ and record the level of the ___________________ Add the object to the water and record the ____________ _______________________; Add the object to the water and record the ____________ _______________________; Subtract the ________ volume from the _________ volume _________. Subtract the ________ volume from the _________ volume _________. completely submerge the object water (initial volume A) new water level (final volume B) initial final (B - A)

6. Water Displacement (con’t) Example: measure the volume of the dinosaur Example: measure the volume of the dinosaur Initial volume of water = ___________ Initial volume of water = ___________ Final volume of water = ___________ Final volume of water = ___________ Volume of dinosaur = ______________ = Volume of dinosaur = ______________ =______ 4.8 mL 5.6 mL 5.6 mL – 4.8 mL 0.8 mL
