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. 

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

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...

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...

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, lesson procedures, and associated worksheets are all...

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...

Finish or launch your unit on the solar system with a jigsaw project covering major celestial concepts such as the Milky Way Galaxy, asteroids, meteors, comets, Earth's moon, and, of course, all the planets. Learners start by...

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...

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...

These may not all be your cup of tea, but you'll likely find some gold in this math games packet. Find brief, easy-to-execute games (like Integer Football) and that are perfect for review or even a substitute teacher plan. 

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...
