Carolina Chemonstrations®: Energy Transformations with Irradiated Salt Kit

Item # 840357 Exclusive

Spark your students’ interest in atomic theory and structure with this teacher-led, student-engaged demonstration kit. Students observe thermoluminescence from irradiated salts on a hot plate and learn about excited states of electrons. They calculate the energy released during these transitions and relate their observations to real-world applications of ionizing radiation. This demonstration requires approximately 10 min and materials are sufficient for 5 demonstrations.

  • Observe thermoluminescence from irradiated salts
  • Illustrate and explain electron excited states on a particulate level
  • Demonstrate the release of photons as excited electrons fall back to a lower energy
  • Relate observations to real-world examples of ionizing radiation

This teacher-led, student-engaged demonstration kit gets students thinking about the particulate interactions that result in thermoluminescence. Students observe colorful sparks from irradiated salts on a hot plate and learn about the excited states of electrons. As irradiated lithium chloride and sodium chloride are heated, they undergo thermal fluorescence and release photons that can be seen as visible light. Students calculate the energy released during these transitions and relate their observations to real-world applications of ionizing radiation. The 2 irradiated salts in this kit have been irradiated with gamma radiation but are not themselves sources of ionizing radiation. This demonstration requires approximately 10 min and materials are sufficient for 5 demonstrations.
