What you'll learn

  • Find out just how BIG and FAR and FAST things really get in Space.

Course content

8 sections • 18 lectures • 2h 38m total length

  • Introduction1:37

    Introduces the idea that big is relative in space. This downloadable module fits a semester or year of astronomy as an accredited curriculum for homeschoolers or charter schools.

  • Objective & Warm Up Activity1:02

    Distinguish the relative concept of size by comparing the earth with larger cosmic objects, and practice ordering objects by size through warm-up activities.

  • Big is Relative12:55

    Explore how size is relative, comparing Earth, the Sun, and distant stars. Understand how mass, density, and gravity govern scale from planets to galaxies.

  • Test Questions0:30

    Access and download 25 assessment questions from here or your resource folder, and choose to answer verbally, on paper, or by rereading the lesson; answers appear in the next section.

  • Test Answers0:18

BIG, FAR and FAST challenges your concept of what constitutes size, distance and speed in astronomical terms.

BIG looks at size in the universe by comparing celestial objects with the sizes of things we are more familiar with close by.

FAR takes you on an amazing trip around the universe on a plane, the space shuttle and finally a beam of light to understand how far things really are in space.

FAST
Learn about speed in space and on the Earth, and see how an object’s movement effects the object and everything around it – even time.
