Last week, Honors Chemistry students illuminated their studies with a vivid investigation into how atoms reveal themselves through light and color.
In the Flame Test Lab, students observed the unique colors emitted by different metal ions when heated in a Bunsen burner flame. Using water-soaked wooden stirrers to introduce each compound, they tested 14 samples and recorded their observations in a table that included the compound name, formula, and the corresponding flame color. The results showcased a variety of shades of red, green, orange, purple, and yellow. Students then used this data to identify one unknown substance that burned with a bright orange flame.
After gathering their results, students moved from observation to interpretation, connecting each flame color to fundamental concepts of light, such as wavelength, frequency, and energy. They noted that blue light has a higher frequency and energy than red light. Class discussions encouraged students to predict the colors of flames for new compounds, write electron configurations, and identify valence electrons.
By translating color into evidence and understanding, the experience enhanced students' scientific reasoning and communication skills, enabling them to support their claims with clear data. With this strong foundation, students are now better equipped to apply their reasoning in future units and investigations.
