Curated OER
The Big Bang-Hubble's Law
In this Hubble's law worksheet, students use data for galaxies which include their distance and speed. Students make a graph to show the distance to each galaxy and the speed of each galaxy. They use their graph to answer 4 questions...
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
Learners 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.
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.
