This is an activity during Solar Week, a twice-yearly event in March and October during which classrooms are able to interact with scientists studying the Sun. Outside of Solar Week, information, activities, and resources are archived and available... (View More) online at any time. This is an activity about telling time using the Sun. Learners will create a solar shadow tool and use it to chart changes in the Sun's altitude through the seasons. This activity is scheduled to occur during Thursday of Solar Week. The activity requires access to a sunny outdoor location over the course of several days, weeks, or months, as well as materials and equipment such as pine board, dowel rod piece, drill and drill bit, saw, bulls-eye level, small nails, and either wood glue or hot glue.

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)

The 9-session NASA Family Science Night program invites middle school children and their families to discover the wide variety of science, technology, engineering, and mathematics being performed at NASA and in everyday life. Family Science Night... (View More) programs explore various themes on the Sun, the Moon, the Stars, and the Universe through fun, hands-on activities, including at-home experiments. Information about Family Science Night implementation and support resources, including the facilitator's guide, are available by registering on the Family Science Night Facilitators website (see Related & Supplemental Resources for link).

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 an activity about seasons. Learners compare the seasons though identifying seasonal activities and drawing scenes in each season. Then, they compare the temperature on thermometers left under a lamp for different lengths of time to explore... (View More) how Earth heats more when the Sun is in the sky for longer periods of time. Finally, learners use a flashlight and a globe to investigate how the spherical shape of Earth causes the seasons to be opposite in each hemisphere. This hands-on activity is an additional lesson as part of the book, Adventures in the Attic. (View Less)

This is a book about seasons. Learners will read or listen to a story about two twins, Matt and Matilda, who are tasked with creating a model of the Earth-Sun system for a science fair project. Through some wild seasonal changes they experience... (View More) while creating the model, the two come to a better understanding of the causes Earth’s seasons. Additionally, an extension activity is included, Reasons for the Seasons, as well as reading and vocabulary activities. (View Less)

In this activity, learners draw a circle with a single focus, an ellipse with two foci close together, and an ellipse with two foci far apart, and compare the shapes. Learners then measure the Sun in four images each taken in a different season,... (View More) comparing the apparent size of the Sun in each image to determine when Earth is closest to the Sun. This is the second activity in the SDO Secondary Learning Unit. The activity is reprinted with permission from the Great Explorations in Math and Science (GEMS). (View Less)

This is an activity about the motion of the Earth around the Sun. Learners will act out the motions of Earth as it orbits around the Sun over the course of one year, starting with modeling one day, then one year, and finally the months.

In this kinesthetic activity, learners act out the rotation and revolution motions of Earth around the Sun over the course of one year. Learners also physically model the tilt of the Earth and will identify the summer and winter solstice and vernal... (View More) and autumnal equinox locations in relation to Earth's orbit around the Sun. (View Less)

This is an activity about seasons. Learners begin by brainstorming a list of activities and events that occur in each season. Next, learners perform an experiment by comparing the temperature on thermometers left under a lamp for different lengths...
