  1. Measurement-A Common Language Volume

  2. Volume • The amount of space matter can occupy. OR • The amount of matter an object can contain.

  3. When measuring the volume of a liquid, scientists use a unit known as the… • Liter (L).

  4. To measure the volume of smaller liquids we use the….. • Milliliter (mL)

  5. The instrument used to measure the volume of liquids is called the… • Graduated cylinder.

  6. Meniscus • The curve in the top surface of water in the graduated cylinder

  7. Observing - What is the proper way to read a meniscus? • Read the milliliter marking at the bottom of the curve

  8. Volume Volume of Rectangular Solids

  9. How can the volume of a solid object be measured? • To measure a rectangular object such as a shoebox, multiply the object’s length, width, and height

  10. The Metric unit known for measuring solids with a larger volume is known as the… meter (m).

  11. The formula for calculating the volume of a rectangular object is: Volume = Length x Width x Height

  12. Why is the unit cm³ used when calculating the volume of a rectangular object? • When multiplying the object’s length, width and height, the cm units are also multiplied cm x cm x cm = cm³

  13. Practice: A shoe box has a length of 10 cm, a width of 4 cm and a height of 20cm. Volume = Length x Width x Height Volume = Volume =

  14. Volume Volume of Irregular Solids

  15. How is the volume of an irregular solid such as a rock measured? • To measure the volume of an irregular solid, immerse the object in water, and measure how much the water level rises • Water displacement method

  16. How does the water displacement method work? • Record the volume of water in the graduated cylinder • Carefully place the irregular solid into the water. Record the volume of the water plus the object • Subtract the volume of the water alone from the volume of the water plus the object

  17. Density • Density is a measure or how much matter is packed into a given volume. • To find density you simply divide the mass by the volume. d=m/v
