X-ray Spectroscopy and the Chemistry of Supernova Remnants
This link takes you to a comprehensive unit that delves into emission spectra and supernovas. There are four parts: How and where elements are created, electromagnetic radiation, spectroscopy, and the newest technology for studying our...
Curated OER
How Big Is That Star?
Aspiring astronomers study stars. They compare stars and explain the relationship between radius, mass, and diameter. By creating a star simulation, they discover how a binary star system's orbit can cause changes in the observed...
Curated OER
Electromagnetic Radiation
High schoolers explore the nature of electromagnetic spectrum through a series of experiments. For this physics lesson, students determine how light behaves under certain circumstances. They explain how humans perceive colors.
Curated OER
Radiation Reassessed
Students investigate the dangers of radiation by exploring recent nuclear tragedies. In this scientific debate lesson, students define the idea of radiation "half life" and determine if low doses of radiation are truly damaging to...
Curated OER
An Overview of Solar Radiation
Students examine the Stefan-Boltzmann Law. Students compute basic radiative "constants" of the sun-Earth-atomosphere system. They examine the wavelength of maximum radiation emission.
Curated OER
How Does Radiation Affect You?
Students identify the use and misuse of radiation. They examine human activities that add to the exposure of radiation. They also discover how it can be useful in saving lives.
Curated OER
Chemical Sleuthing
Students engage in a lesson which includes flame tests and the construction of a simple diffraction spectrograph with which to measure sodium ion emissions. They use the Bragg equation to compute the wavelength of the line spectra produced.
