In this activity, learners will discuss possible reasons for the seasons, create a list of suggested factors, test these factors in research groups, and report their findings in a symposium format. This is Activity B-9 of Universe at Your Fingertips... (View More)

This is an activity about the size and scale of the Sun-Earth system. Learners will take an imaginary trip to the Sun by comparing images of the Sun and Earth at different points in altitude above the Earth. This is to ultimately conceptualize the... (View More)

This is an activity about how the Earth's axial tilt causes its seasons. Learners will make a model using polystyrene spheres and a light bulb to represent the Earth-Sun system, showing why the tilt of the Earth’s spin axis causes its seasons due... (View More)

Audience: Middle school
Materials Cost: $1 - $5 per student

This is an activity about seasons. Learners will analyze monthly temperature data from various cities around the globe in order to dispel the misconception that the distance between Earth and Sun may be responsible for the seasons. This is Activity... (View More)

Audience: Middle school
Materials Cost: Free per group of students

This is an activity about the rotation of the Sun. Learners examine images of the Sun taken by the Yohkoh satellite, use a grid overlay to mark the positions of the sunspots, and then calculate the rate at which the spots move to determine the... (View More)

This is an activity about graph interpretation. Learners will compare, interpret, and discuss four graphs of the speed, temperature, magnetic field strength, and density of a coronal mass ejection as it swept past Earth in 1997. This is the third... (View More)

This is an activity about the solar activity cycle. Learners will construct a graph to identify a pattern of the number of observed sunspots and the number of coronal mass ejections emitted by the Sun over a fifteen year time span. A graphing... (View More)

This is an activity about the movement of a coronal mass ejection. Learners will plot the path of two coronal mass ejections (CMEs), both the distance traveled and the increasing angular width, as they leave the Sun and travel outward through the... (View More)

This is an activity that uses numerical information to help dispel the prior conception that distance from the Sun causes the seasons on Earth. Learners will examine two images of the Sun, taken six months apart, measure the apparent diameter of the... (View More)

Audience: High school

This is a lesson plan for several related activities about the Sun. Learners will observe how a candle flame is like the Sun, brainstorm why the Sun is needed and how energy from the Sun is used, construct a Sun-Earth scale model illustrating both... (View More)
