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)

This is an activity about constellations. Learners will create a simple star finder using basic materials and learn to use it to be able to identify constellations in the night sky for various dates and times. The star finder can also be used to... (View More) reinforce the concept that the sky seems to change in a predictable pattern. This is Activity F-3 of Universe at Your Fingertips 2.0: A Collection of Activities and Resources for Teaching Astronomy DVD-ROM, which is available for purchase. (View Less)

This is an activity exploring the connections between astronomy and culture. Learners will design their own constellation pattern based on the stars representing Ursa Major and write a short story to go along with their design. Then, they will share... (View More) their pictures and stories to the group and discuss how other cultures around the globe have viewed the same group of stars and created their own myths to explain them.

This interactive, computer-based activity presents a series of inquiries that allow students to discover how the colors, masses, and luminosities of stars are related. Students also investigate how these characteristics influence the life cycle of... (View More) the stars. The concluding activity allows students to use the information learned in the previous activities to determine the eventual fate of our Sun. The activity is part of the Space Mysteries series.
