As 2 different irradiated salt samples are heated, students observe bursts of light. This phenomenon provides evidence that the crystals’ electrons were previously energized to an excited state. Students apply prior knowledge of chemical and physical properties to develop a model for what is happening at the atomic level. After a discussion, students revise their model and make predictions on what will happen if conditions are changed.

Time Requirement
Total, 10 minutes. Teacher prep, 5 minutes. Demonstration and discussion, 5 minutes.

Digital Resources
Includes 1-year access to digital resources that support 3-dimensional instruction for NGSS. Digital resources may include a teacher manual and student guide, pre-lab activities and setup videos, phenomenon videos, simulations, and post-lab analysis and assessments.

Learning Objectives

  • Use prior knowledge to make predictions and then develop models based on observations and prior knowledge.
  • Illustrate and explain thermoluminescence on a particulate level and learn that short-wavelength electromagnetic radiation can ionize atoms.

Prerequisite Knowledge and Skills
Students need a knowledge of atomic structure, the location of subatomic particles, and how atoms are ionized. They should also have a familiarity with the electromagnetic spectrum and an understanding of the relationship between frequency, wavelength, and energy.
