Supernova Chemistry
By measuring the wavelength, frequency, and intensity of electromagnetic radiation, scientists determine the temperature, density, and composition of far away items. Scholars rotate through ten lab stations using a spectroscope at each...
Curated OER
The Guest Investigator Puzzle
Learners conduct a brief astrophysics lab matching the EUVE spectra of various kinds of "mystery" stars with the spectra of known stars taken at Extreme Ultraviolet and optical wavelengths to determine their type.
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
Time That Period
Physical science starters play with a pendulum in order to experience periodicity. Detailed procedures and a worksheet are included for day one. For day two, learners will use a graphing calculator to help them plot orbit data from a...
Curated OER
What's the Frequency, Roy G. Biv?
Students examine the concept of frequency and wavelength. They analyze how frequency and wavelength relate to each other by conducting an experiment involving measuring and timing wavelengths by pulling adding machine tape through an...
Curated OER
Time That Period!
Students analyze data received from high-energy satellites of various binary star systems' orbital periods or stellar rotation periods.
