Learners will explore different ways of displaying visual spectra, including colored "barcode" spectra, like those produced by a diffraction grating, and line plots displaying intensity versus color, or wavelength. Students learn that a diffraction... (View More)

This interactive, online activity introduces the idea that everything emits electromagnetic radiation, including students. Students discover how the light emitted from an object (a robot) changes as the object is heated. A graph shows the amount of... (View More)

This is an online lesson associated with activities during Solar Week, a twice-yearly event in March and October during which classrooms are able to interact with scientists studying the Sun. This activity is scheduled to occur during Monday of... (View More)

This interactive, online activity introduces students to the electromagnetic spectrum. Students view the electromagnetic spectrum in its entirety and become familiar with the characteristics of waves. Images of the sun in different wavelengths of... (View More)

This is a lesson about using the light from the star during an occultation event to identify the atmosphere of a planet. Learners will add and subtract light curves (presented as a series of geometrical shapes) to understand how this could occur.... (View More)

Traditionally, spectral images are two dimensional, and related to text. This kinesthetic activity has groups of students position themselves along a printed spectrum to make spectral patterns and model various elements. Includes photos, teachers... (View More)

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)

This modular activity traces the history of telescope development and highlights the interplay between technological and scientific advances. Milestones in telescope development are highlighted in the ten sections called "eras," with specific... (View More)
