This activity enables students to better understand the motion of the Sun and how we use it to measure time. Students create a "horizon calendar" at their school by carefully observing and recording the horizon and the Sun at sunset (or sunrise, for... (View More)

This activity explores how ancient Sun observers made use of natural and built structures to mark solar alignments observed at different times of the year, particularly around the solstices and equinoxes. In Part 1, the teacher prepares a horizon... (View More)

This is a lesson plan for an activity that explores time zone math. Learners will translate their local time to times in other zones around the world and work with the concept of Universal Time, specifically in reference to the reporting,... (View More)

In this activity, students learn the basics of the horizon, direction and the rising and settings of the Sun and stars by making a schoolyard "medicine wheel" with sidewalk chalk on playground asphalt. Medicine wheels are stone rings constructed by... (View More)

This is a web site which explores the desire shared by past civilizations and today's society to observe and study the Sun. Learners can access two interactive modules, which include satellite images, aerial photographs, panoramic pictures,... (View More)

In this activity, students engage in long-term systematic observation to learn about the apparent annual motion of the Sun caused by the Earth’s orbit around the Sun. Students put a dot on a window where sunlight enters the classroom (or any room... (View More)

In this activity, students learn about the motion of the Sun in relation to the Earth, and how geographic directions are defined. Students use a tetherball pole (or an alternative) as a gnomon and the shadow the Sun casts to determine the exact... (View More)

This is a lesson plan for an activity about the nature of the Sun's apparent motion throughout the day. Learners will follow detailed instructions to construct a sundial using everyday materials and make measurements of the shadow cast by the... (View More)

This is a lesson plan for an activity illustrating the reasons for the seasons. Learners predict sunrise, noon, and sunset positions on the dates of the equinoxes and solstices, observe these positions in a planetarium, plot their data on graphs,... (View More)
