This is an activity about the expansion of the Universe. Learners will use a special set of transparency and master sheets with dots representing clusters of galaxies at two different eras of the Universe's history. After aligning the transparency and underlying page, learners then observe and measure clusters moving away from particular locations, graph their data, compute a slope and relate the slope to the age of the Universe. This is Actividad 8.4 as part of El Universo a Sus Pies, a Spanish-language curriculum, available for purchase.
