Take a virtual tour of the solar system starting with detailed information about the sun.

Use the following lithographs to envision the scale of our solar system. View different models of planets at different scales, an infographic about the relative sizes of the planets and distance from the sun, and images of the largest...

Teach the concept of scale models and the size of the solar system through this extensive lesson plan. Students will learn about scale models, estimate which objects to use to create a scale model of Earth and Sun, and figure out how far...

Discover interesting information about the planet Venus through a vast archive of photographs and scientific facts.

For this science lesson students will work collaboratively to learn and introduce the eight planets, sizes, characteristics, and their order. They will use size comparisons, research a planet, design a poster and create a PowerPoint...

Enter our solar system to interact with the planets, moons, asteroids, meteors, and more. Investigate with NASA scientists and explore missions related to space exploration. Read facts, compare statistics, look through resources, and...

This activity explores the relative size of the eight planets that circle around the Sun.

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.

Examine the variety of weather found on all of the planets in the solar system with this classroom exercise. Students will see a video and observe differences and similarities among the planets.

Discover interesting facts about Jupiter, the largest planet in the solar system.

Discover interesting facts about Saturn, the second-largest planet in the Solar System.

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.

A brief overview of Titania, Uranus's largest moon. Includes a very good description of the moon's surface. A NASA picture of the day.

An article about the Planetary Science Institutes's advanced computer software, which it uses to model the way the solar system may have formed. Includes some insights into the results already obtained.

Constellation of articles, images, diagrams, posters, videos, and more on the subject of the search for planets, particularly Earth-like planets, outside our solar system.

Explore the mythology, structure, observational history, gravitational force, and orbit of Earth's Moon.

The purpose of this activity is to use scaling in order to give students an idea of the size of Mars in relation to the Earth and the Moon as well as the distance between them. The students will have to calculate dimensions of the scaled...

Flip this interactive card to start learning about Jupiter, the largest planet in our solar system. Answer multiple-choice and fact-or-fiction questions and review some fast facts about Jupiter.

Students explore the outermost planets of our solar system: Saturn, Uranus and Neptune. They also learn about characteristics of Pluto and its interactions with Neptune. Students learn a little about the history of space travel as well...

In this simple lesson, students grow yeast to learn how the climates on each of the nine planets would affect life.

Discover interesting facts about Mars, the furthest planet from the sun.

Young scholars are introduced to the fabulous planet on which they live. Even though we spend our entire lives on Earth, we still do not always understand how it fits into the rest of the solar system. Students learn about the Earth's...

Students learn how engineers navigate satellites in orbit around the Earth and on their way to other planets in the solar system. In accompanying activities, they explore how ground-based tracking and onboard measurements are performed....

This site is astronomy for kids and teachers! Here students can learn about the planet Earth of the Solar System including fun facts, mass, day, year, and distance from the Sun.
