Warm-Up and Preparation

  • Divide students into lab groups and give each a candle, match, candle holder, paper and colored pencils.
  • Remind students of safety protocol and expectations when handling fire, then instruct them to light their candles.
  • Once lit, have students draw a sketch of the flame in their notebooks, using the colored pencils and paying close attention to colors.
  • When finished, have students share their drawings and answer these questions in their lab groups:
    • What did you notice about the color of the flame?
    • Why do you think parts of the flame were different colors?
    • Which part of the flame do you think was the hottest? Why?
    • How may the colors of the flame relate to heat?
  • Have students blow out their candle and collect supplies, then ask students to share their prior understanding of stars with their lab groups and hypothesize the connection between stars and the candle experiment.
