Matter has mass and volume. LESSON 1.1 Matter has mass and volume.
MATTER Def: anything that has mass and takes up space Examples: air, pencils, books, skate boards and YOU All matter is made of atoms.
MEASURING MASS Def: how much matter an object contains Unit of measure – gram (g) Tool used for measuring – Triple Beam Balance Mass always stays the same
MEASURING WEIGHT Def: downward pull on an object due to gravity Measured with a scale – usually a spring scale Unit of measure – pound Weight changes as the pull of gravity changes
MEASURING VOLUME Def: amount of space matter occupies Can be determined 2 ways: 1) Formula: length x width x height Tool: metric ruler Unit: cm³
2) Volume by Displacement used for irregular shaped objects MEASURING VOLUME 2) Volume by Displacement used for irregular shaped objects Tool – graduated cylinder Unit – mL Measure amount of water to start, then measure water level after the object is added, then subtract. Difference = volume
