Student Internet investigation that explores light, radiation and the Sun. The activity is divided into two parts. Part one gives students a good overview of what light actually is; the electromagnetic spectrum, and spectroscopy (the study of light). Part two explores the Sun's internal structure, atmosphere, magnetic anomalies; and solar events such as sunspots, flares and coronal mass ejections and their effects on Earth.
The latest links containing images and data are presented as well for these topics. I use this computer lab activity as a review for my astronomy class as part of the Unit VI "Light and the Sun" review but it can also be used at an 8th grade level Earth/Space web quest. (Some students will finish the activity within one class period but generally it will take about an hour or so to complete.)
Topics/terms in this activity include:
Electromagnetic waves, EM spectrum, Sun, stars, radio waves, infrared rays, visible light, ultraviolet rays, x-rays, gamma rays, wavelength, frequency, spectrum, blackbody radiation, transverse velocity, radial velocity, star motion, spectroscope, continuous spectrum , emission spectrum , emission lines, absorption lines, spectroscopy, atoms , nucleus , neutrons, element , ground state, ionized , excited states , quantized, photons , molecules, star, photosphere, core, radiation zone, convection zone, granulation, chromosphere , transition zone, corona, solar wind, sunspots, sunspot cycle , solar cycle, prominences, flares, Coronal Mass Ejections (CME’s), nuclear fusion
