The star maps can be used to find constellations and identify stars with extrasolar planets.... (View More) (Northern Hemisphere only, naked eye) (View Less)

This is an activity about the Doppler effect. Learners will use long springs or ropes to examine the frequency and wavelength of various waves. Then, they will observe a demonstration of the Doppler effect for sound waves, using this understanding... (View More) to investigate the shifted spectra of sample galaxies. Finally, learners will user their data to create a graph of distance versus recession speed, illustrating Hubble’s Law regarding the expansion of the Universe. This is Actividad 8.3 as part of El Universo a Sus Pies, a Spanish-language curriculum, available for purchase. (View Less)
