Researchers use scientific data to understand what is inside each of the planets. The first in a series of six, this lesson builds off of that concept by having pupils use a data table to create their own scale models of the interiors of...

Between the time scientists discovered Pluto and reclassified it as a dwarf planet, it did not even make one full revolution around the sun. In two activities, scholars investigate scale models and their properties. Pupils find that it...

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.

Add a visual aid to your solar system lessons. Enthusiastic astronomers create a model depicting the nine planets and their distance from the sun. 

Did you know that Pluto is smaller than the United States of America? It is difficult to conceptualize the size of planets and the distance between them, and the instructional activity addresses those exact issues. After a discussion,...

Ever wonder why Pluto isn't considered a planet? Or how large the Earth is compared to the other inner planets? Explore the universe with a series of projects that simulate different aspects of our solar system. The activities require...

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...

Students explore the Solar System and examine the characteristics of al the planets. Through research and discussion, they create catalogs of the Solar System's components. Next, students use their findings to create Powerpoint...
