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...

The density of the huge planet of Saturn is 0.7 g/cm3, which means it could float in water! In the second part of 22, science pupils explore the size and order of the planets. They then calculate weight and/or gravity and density of...

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...

Can we model how large the solar system really is? Attempt an astronomical feat with a hands-on-activity that uses a roll of toilet paper. Young scientists measure the distances of the planets from the sun to create a scale model of...

Create a scaled model of our solar system in your classroom! Scholars work collaboratively to build paper mache planets and hang them in their proper position to showcase each planet's location in the solar system.   

There's no need to stay inside; get out of the classroom and create a scaled map of the solar system on your playground field! In collaborative groups, scholars identify the distance between the sun and other planets, place planet...

Creating a solar system map is a snap thanks to a hands-on activity! Science scholars explore the solar system by building it wherever they choose during an interactive from PBS's Space series. Users pick both the location and scale for...

In 2006, New Horizons began its mission to fly to Pluto. As it continues its journey, scholars track its progress with the help of an informative website, all the while reinforcing measurement concepts with the construction of a scaled...

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...

The propellant needed for space explorations runs in the thousands, while paying to get the craft into orbit costs millions! In the second installment of three, two activities explore laws of conservation of energy and momentum. Using...

Scholars go on a hunt to locate objects that best fit the measurements to create an eye-catching scale model of the solar system. 

Get crafty with the help of pictures and a real-time demonstration from a video that details the step-by-step process in creating a paper solar system.
