Reflectivity of Light

Experiment #35 from Elementary Science with Vernier

Education Level
Elementary School


Light is reflected from surfaces based on their texture and color. The amount of light reflected is called the reflectivity of the surface. Reflectivity is important in determining our climate on Earth. Things like oceans, trees, ice, and deserts greatly affect how much of the sun’s light energy is reflected and how much heats the Earth.


In this activity, you will

  • Use a Light Probe to measure reflected light.
  • Make conclusions based on your data.
