This is a set of instructions for building a physical model. The model simulates the Sun's paths across the sky at summer solstice, winter solstice, and the spring and fall equinoxes. A bead simulates the Sun, moving along a cord, from rising along... (View More) the eastern horizon to setting on the western. The bead can be moved from path to path to demonstrate solar alignments, the solstices, and equinoxes. The model is created to be unique to the user's latitude, and is useful for including in lessons that teach about the seasons or archaeoastronomy. (View Less)
Learners explore Earth's rotation and the Moon's role in our 24-hour day, using their bodies to explore and model the Earth's daily motions in this kinethetic exploration. They relate the motion of the Earth about its axis (rotation) to the... (View More) appearance of the sky over the course of the day. Learners consider the role of the Moon in slowing Earth's rotation over time; if the Moon didn't exist, Earth might be spinning more quickly, giving us an eight-hour day! This activity is part of Explore! Marvel Moon, a series of activities developed specifically for use in libraries. (View Less)
This is an online set of information about astronomical alignments of ancient structures and buildings. Learners will read background information about the alignments to the Sun in such structures as the Great Pyramid, Chichen Itza, and others.... (View More) Next, the site contains 10 short problem sets that involve a variety of math skills, including determining the scale of a photo, measuring and drawing angles, plotting data on a graph, and creating an equation to match a set of data. Each set of problems is contained on one page and all of the sets utilize real-world problems relating to astronomical alignments of ancient structures. Each problem set is flexible and can be used on its own, together with other sets, or together with related lessons and materials selected by the educator. This was originally included as a folder insert for the 2010 Sun-Earth Day. (View Less)
This is a companion book to the Traditions of the Sun web site. Learners can use the book to learn about the Sun's dynamic nature, explore images from NASA's cutting-edge solar missions and understand more fully the human connection we all have to... (View More) our Sun. The book also allows learners to see how the Sun-Earth connection is made at Chaco Canyon, including the sunrise over Chaco Canyon's great kiva, celebrations of the changing seasons in the Southwest and the Great Houses whose placement required precise observations of the Sun and stars.
