Exploring Big Bang Evidence – Grade Nine
Students will examine scientific evidence on The Big Bang Theory. This lesson provides inquiry activities for some, but not all, lines of evidence on the Big Bang. Students will apply research guidelines to access scientifically valid evidence via library and/or Internet searches. Students will organize information regarding the background (blackbody) cosmic microwave radiation, Hubble's Law and stellar spectra. Lesson activities include modeling the relationship between color and temperature and investigating relationships between brightness, distance and temperature. Extensions will give students the opportunity to do inquiry activities to "fingerprint" stellar spectra. Students will create a presentation that links the evidence with the theory.
