Young scholars discover how astronomers used the diameter of the Earth's orbit around the Sun as a baseline for estimating the distance of some stars, and the meaning of "Parsec" and "light year."

In this nebula worksheet, students read about the Chandra X-ray Observatory that captured the given image of a pulsar and its nebula. Students solve 3 problems including using similar triangles and proportions to find the image width,...

In this single variable equations worksheet, students solve 5 problems using different equations to solve for one unknown. They use Hubble's Law to find the velocity of a galaxy knowing the distance it travels.

In this unit conversions worksheet, students solve 13 problems using given conversion factors to convert measurements from one unit of measurement to another.

In this variables and expressions worksheet, high schoolers solve 7 problems using different mathematical formulae to find the length of Earth's day in the future, the distance to the galaxy Andromeda, the temperature of a gas cloud...

In this galaxy worksheet, students use the Internet or other resources to answer 13 questions about the galaxy NGC-1232. They are given a photograph of the galaxy to help determine the width and diameter of certain regions of...

Young scholars investigate stars and the solar system by completing a worksheet.  In this space science lesson, students complete a fill in the blank worksheet based on the stars and components of the cosmos. 

Students discover the vocabulary used for distances in space and review measurement units and instruments before creating a scale model of the planets. They determine how to calculate the relative distances between the planets using a...

In this interactive prepositions worksheet, students practice using prepositions in sentences. Students choose the correct preposition for each blank in the passage. There are fifteen in all.

In this bellwork on the electromagnetic spectrum and planets worksheet, students answer questions about the information determined using a spectroscope, the geocentric and heliocentric models of planet rotation and the planets.

In this interactive tutorial students will explore galaxies. Learn what the Milky Way Galaxy is like, how various galaxies are grouped into clusters and superclusters and why those particular galaxies clump together.

This learning module includes a nonfiction reading passage about galaxies including the Milky Way followed by a multiple choice self-assessment which gives students immediate feedback.
