Don't just look at pictures of the Milky Way galaxy, build it with this hands-on activity in which scientists recreate the galaxy we live in.

How do you put something as large as the universe in perspective? Use a series of scale experiments. Classmates collaborate around four experiments to examine the scale of the earth-moon system, our solar system, the Milky Way galaxy,...

In this Drake Equation learning exercise, students read about how scientists can estimate the number of intelligent civilizations that may exist in our galaxy. Students answer 7 questions about the Drake Equation and they use the...

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...

Supernova explosions mark the end of a star's life. Guide the class through an investigation that uses data to calculate the age of a supernova remnant. Using provided data and online software, they analyze data to determine the radius...

The number of craters on the surface of solar system objects has a direct correlation to its age. Learners use the concept to determine the age of several objects in the solar system. Using satellite images, they count craters within a...

Young scientists create a simulation of Hubble's law. Introducing the Big Bang Theory using balloons and a simple lab activity, scholars complete a data table and perform analysis.

Assist your pupils and broaden their horizons with several activities that determine the exact positioning of various communities over the globe. Pupils use data from the Global Positioning System to determine the position and rate of...

The Milky Way is the edgewise view of our home galaxy, a disk made up of billions of stars. The Sun resides on one of the spiral arms of the disk, 30,000 light-years from the thick hub of the galaxy. The actual center, with a black hole...

Globular clusters, compact groups of about a million stars that move around together in galaxies, are among the oldest objects found in the universe. Since they are found most galaxies and since they've been around for so long, globular...

When you are in the city, only a few of the brightest stars are visible. But when you are in the country, you can see many more stars than you can count. Sometimes you can even see the bright belt of our galaxy, the Milky Way. In this...
