The Color Temperature is a captivating experiment that demonstrates the concept of color temperature and how different light sources emit different colors of light. In this activity, participants will observe and compare the color temperatures of various light sources to understand the relationship between temperature and the color of light emitted.

Materials Needed:

  • Different light sources with various color temperatures (for example, incandescent bulb, fluorescent bulb, LED bulb, candle, natural sunlight, etc.)
  • White or neutral-colored surfaces (for example, white cardboard, paper, or fabric)
  • Optional: Light meter or smartphone app with a color temperature measurement feature

Instructions:

  1. Introduction: Begin by introducing the concept of color temperature and its relevance to different light sources. Explain that color temperature is a measure of the color of light emitted by a source, often measured in Kelvin (K).
  2. Light Sources: Gather various light sources with different color temperatures. For example, you can include an incandescent bulb (warm light), a fluorescent bulb (cool light), an LED bulb (neutral light), a candle (warm light), and natural sunlight (daylight).
  3. Setup: Set up the light sources in a darkened room or space, ensuring each light source illuminates a white or neutral-colored surface (cardboard, paper, or fabric).
  4. Observations: Have participants observe and compare the colors of light emitted by each source. Encourage them to describe the differences they see and note any color shifts.
  5. Color Temperature Measurement (Optional): If available, use a light meter or smartphone app with a color temperature measurement feature to measure the color temperature of each light source. Compare the measured values with participants’ observations.
  6. Discussion: Lead a discussion about the color temperature of each light source. Explain that lower color temperatures (for example, around 2700K) are associated with warm, reddish light, while higher color temperatures (for example, around 5000K to 6500K) are associated with cool, bluish light.
  7. Applications: Discuss real-life applications of color temperature, such as in photography, filmmaking, and indoor lighting choices.
  8. Lighting Preferences (Optional): Ask participants to share their preferences for different lighting scenarios and color temperatures based on personal preferences or specific activities.

Safety Precautions:

  • Handle light bulbs and electrical equipment with caution to avoid electric shock or injury.
  • Adult supervision is recommended, especially when dealing with electrical components.

The Color Temperature provides an opportunity for participants to explore and understand the concept of color temperature and its impact on the color of light emitted by different sources. It promotes observation, critical thinking, and an appreciation for the science behind lighting and its applications in various settings. Additionally, the activity encourages participants to consider the importance of color temperature in designing lighting environments for different purposes.
