Did you know scientists can tell the age of an asteroid by looking closely at its craters? This final lesson of a six-part series focuses on two asteroids, Gaspra and Ida, in order to demonstrate the concept of dating asteroids. Scholars...

How in the world can something as big as the solar system possibly fit in your pocket? Complete this simple modeling activity and find out, as young scientists gain an appreciation for the incredible scale of outer space.

Trying to understand the vastness of outer space can be quite a challenge for young scientists. Help put things in perspective with this cross-curricular activity as students work in pairs creating scaled models of...

Why do scientists use models? In the first installment of 22, groups create scale models of our solar system. They then share and discuss their models.

Math and science come together in this cross-curricular astronomy lesson plan on planetary motion. Starting off with a hands-on activity that engages the class in exploring the geometry of circles and ellipses, this lesson...

Use a variety of whole fruits to represent the different planets in the solar system to introduce scale sizes to your math or space science class. They follow suit by creating a non-scaled model of the solar system using specific-colored...
