Exploring the Universe: Star Formation

In this activity, learners model a star-formation process by adding energy (via a hairdryer) to matter floating in space (ping pong balls) to see how much of it they can get to "clump" in an empty container.

DESCRIPTION

In this activity, participants will learn how stars form from the dust and gas that exists in space clumping together. They'll model the star-formation process by adding energy (via a hairdryer) to matter floating in space (ping pong balls) to see how much of it they can get to "clump" in an empty container. The more matter they can accumulate, the larger their model star will be. This activity can be adjusted to make it easier for younger participants.

OBJECTIVES

LEARNING GOALS

    1. The space between stars, planets, and other large objects is not empty—it contains gas and dust.

    2. Stars are born when huge amounts of gas and dust clump together.

    3. The more gas and dust that clump together, the higher the new star’s mass.

    4. NASA scientists use telescopes to learn more about how stars form.
