  4. Length Approximations • Kilometer (Km) = 1,000 meters • About the distance from bike rack at LSMS to baseball field at Centennial • Meter (m) • About the distance from the floor to a door handle • Centimeter (cm) = 1/100 of a meter • About the width of your pinky • Millimeter (mm) = 1/1,000 of a meter • About the thickness of a dime

  5. Volume • Amount of space an object takes up • Basic unit is a Liter (L) • We also use milliliter (mL) and Cubic centimeter (cm3) • mL = cm3 • Measure with a ruler and math or graduated cylinder (meniscus)

  6. Volume Approximations • Liter (L) • About the volume of a Nalgene water bottle • Milliliter and Cubic Centimeter = 1/1,000 of a Liter • About one drop from a medicine dropper

  7. Mass • Amount of matter in an object • Basic unit is a Gram (g) • We also use Kilogram (Kg) • Measured with a scale or balance
