This is an activity about how the Sun can affect the Earth's atmosphere, specifically the ionosphere. Learners will use real data from a Sudden Ionosphere Disturbance Monitor, or SID Monitor, to identify the signatures in the graphed data that can... (View More)

This is an activity about modeling the apparent motion of the Sun as seen from Earth. Learners will use a flashlight, toothpick, and styrofoam model Sun to mimic the relative shadow motion produced by a sundial. The activity will help learners... (View More)

Audience: Informal education
Materials Cost: $1 - $5

This is an activity about measuring angular size and understanding the solar and lunar proportions that result in solar eclipses. Learners will use triangles and proportions to create a shoebox eclipse simulator. They will then apply what they learn... (View More)

This is an activity about the relative sizes of the Earth and the Moon and the distance between them. Learners will inflate a balloon to the approximate size of the moon in relation to a standard globe. They will then hypothesize as to the correct... (View More)

Audience: Elementary school, Middle school

In this activity, students engage in an ongoing investigation to find patterns of sunlight and shadow in a classroom (or any room that gets sunlight) at different times of the day and different times of the year. Students look for repeating... (View More)

This is a lesson about magnetism and solar flares. Learners will evaluate real solar data and images in order to calculate the energy and magnetic strength of a solar flare moving away from the Sun as a coronal mass ejection. This is Activity 3 in... (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 a resource that explains the rationale behind the multiple time zone divisions in the United States. Learners will work through a problem set to practice calculating the time in one time zone, given the time in another time zone. This is... (View More)
