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...

Should Pluto be considered a planet or a dwarf planet? Scholars research planets in our solar system to understand their similarities and differences. It also includes memory activities related to the order of the planets. 

New Horizons began its journey to Pluto in 2006. Ten years later, it continues its mission. In that time, scholars have surely grown, but how much more will they grow by the time New Horizons reaches its destination? Find out with an...

Thoroughly written, this plan walks you through every detail of having your high school astronomers design scale models of the solar system. Complete instructions on building to scale, instructional activity procedures, and associated...

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...

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...

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...
