These hands-on activities are a great way for students to gain perspective on the relative sizes and distances of each planet, the relationship between the sun and Earth, and much more.

For the first time, NASA scientists have generated a full image of the sun, front and back, using twin orbiting satellites. The new view of Earth's star will allow for the study of solar weather events like coronal mass ejections that...

This engaging activity introduces students to the concept of albedo and how it relates to Earth's energy balance. They measure the albedo using maps, data tables, and a shaker filled with popcorn kernels. Then, they estimate the Earth's...

This illustration from the Lunar and Planetary Laboratory shows the approximate sizes of the planets relative to each other. Note that the planets are not shown at appropriate distances from the Sun.
