Volume, Mass, and Weight…OH MY !

MATTER: Anything that has mass and takes up space.

MASS: The amount of matter an object has.

Mass Units: Kilograms (kg) or grams (g). Mass is measured using a triple beam balance Mass does NOT change, unless there is weight loss or gain.

Measuring Mass Measuring how much mass an object contains Make sure you “zero the balance” Start with the biggest weight and work toward the smallest

Calculating Mass Start with the hundreds, then add the tens, and last the ones g

WEIGHT: the pull of gravity on an object.

Weight Units: pounds (lb) or Newton (N). Weight is measured using a scale or spring scale. Weight is affected by gravity so therefore it CAN change.

VOLUME: the amount of space an object takes up or contains

Volume of Liquids (irregularly shaped objects) Units: Liters (L) or Milliliters (mL) Measured using a graduated cylinder OR using the displacement method.

Calculating Volume (irregularly shaped objects) Read the volume. Answer: 37 mL or 37 cm³

Volume of Solids (regularly shaped objects) Units: meters cubed (m³) or centimeters cubed (cm³) Measured using a metric ruler.

Calculating Volume (regularly shaped objects) Volume = Length x Width x Height V= 10cm x 5cm x 9cm V= 450 cm³ 10 cm 5 cm 9 cm

Helpful Hints 1mL= 1cm³ So, if a solid displaces 2mL of water in a graduated cylinder then its volume is 2 cm³.
