LIGHT ABSORPTION by chemical substances

LIGHT

MASS – by using different types of balances. The balances included below are arranged according to the amount of precision they provide (from least to most).

  • Even more precise: Analytical Electronic balances
  • Most precise: Micro-Analytical Electronic balances

MOISTURE in soil

OXYGEN (O2) GAS in air

pH of (aqueous) solutions

  • Using litmus paper
  • Using pH test strips
  • Using a universal indicator solution
  • Using Vernier’s pH sensor

PHYSICAL CHARACTERISTICS of stream channels

READING SCALES of lab instruments

SURFACE AREA

TEMPERATURE

TOTAL DISSOLVED SOLIDS in (aqueous) solutions

TURBIDITY of (aqueous) solutions

VOLUME of liquids

  • Using graduated cylinders (Video 1)(Video 2) (Video 3) (Video 4, which pays special attention to accuracy, precision, and uncertainty)
  • Using beakers, cylinders, Erlenmeyer flasks, and volumetric flasks (Video 1)

VOLUME of irregular shaped (solid) objects
