Study Notes

Metric System

  • The metric system is based on the number 10.

Basic Units of Measurement

  • The basic unit of length in the metric system is the meter (m).
  • The basic unit of mass in the metric system is the gram (g).
  • The basic unit of liquid volume in the metric system is the liter (L).

Mass and Volume Conversions

  • 1 gram (g) represents a mass of 0.001 kilograms (kg).
  • 1 liter (L) is equal to 1000 milliliters (mL).

Reading Graduated Cylinders

  • A meniscus is the curved surface of a liquid in a container.
  • To properly read the level of a liquid in a graduated cylinder, place the cylinder on a level surface and read the level at eye level, using the bottom of the meniscus.

Unit Comparisons

  • A centimeter (cm) is larger than a millimeter (mm).

Calculating Area

  • When multiplying two of the same units together to calculate area, square units (e.g. m², cm²) should be used.

Water Displacement Method

  • The water displacement method is used to measure the volume of an object.

Claim and Reasoning Definitions

  • A definition of Claim is not a statement that can be proven or disproven.
  • Reasoning is the process of drawing a conclusion based on evidence.
