Time Intervals
In this time intervals worksheet, high schoolers solve 8 problems where they determine the time gamma-ray bursts last, the time black hole micro-flares are emitted, the time coronal mass ejections travel and the days between lunar phases...
Curated OER
How Far...How Powerful
Students explore the concept of gamma ray bursts. They examine basic physics concepts about light, measure the shifts of spectral lines, and utilize Hubble's Law to deduce the velocity of an astronomical object.

Gamma Ray Bursts
Students study an article on Gamma Rays. In this investigative lesson students study the energy and wavelengths of gamma rays and the theories behind them.
Curated OER
How Far... How Powerfu
Learners work with a real optical spectrum of a gamma ray burst afterglow taken at the Keck Observatory. They measure the shifts of spectral lines, deduce the velocity of the astronomical object, and then use Hubble's Law to get its...
Curated OER
How Far... How Powerful
Students review some basic physics concepts about light, explore redshifted spectra and Hubble's Law, and use them to find out how far away, and how powerful, gamma ray bursts truly are.
