This iOS app for iPhone, iPad and iTouch, allows families and educators to investigate and learn about the Sun at home, at school, or anywhere. It provides 13 free, easy to use, hands-on activities, plus live images of the Sun from NASA's SDO... (View More)

This is an activity about ultraviolet light. Participants will experiment with ultraviolet light sensitive plastic beads, which are generally white but turn colors when exposed to UV light. Participants are informed about the nature and risks of UV... (View More)

This is an activity about sunlight as an energy source. Learners will create a plant box and observe that a plant will grow toward the Sun, its primary source of energy. This hands-on activity is an additional lesson as part of the book, The Day... (View More)

This is a lesson about the electromagnetic spectrum. Learners begin by arranging a set of picture cards; in the discussion afterwards, this activity is related to the electromagnetic spectrum as an arrangement of energy waves. Next, using a... (View More)

This is an activity about magnetism. Using bar magnets, classroom materials, and a compass, learners will explore how bar magnets interact with one another and with other materials, use a compass to find the direction north, and use various... (View More)

This activity demonstrates Lenz's Law, which states that an induced electromotive force generates a current that induces a counter magnetic field that opposes the magnetic field generating the current. In the demonstration, an empty aluminum can... (View More)

This is an activity about the properties and characteristics of Earth’s magnetic field as shown through magnetometer data and its 3D vector nature. This resource builds understanding of conceptual tools such as the addition of vectors and... (View More)

This is an activity about the properties of electromagnets, which is a crucial underpinning for understanding how magnetic fields are generated in nature, in the surface of the Sun, and in the interior of Earth. Learners will create an electromagnet... (View More)
