Classifying Galaxies

Scientists classify everything from the smallest cells to the largest galaxies, but how do they decide on a classification system? Scholars use 40 pictures of galaxies taken by the Hubble Space Telescope to sort and try creating their...

Seventh graders name the different classification of galaxies. In this astronomy lesson, 7th graders sketch and describe the morphology of NGC 1097. They write a paragraph describing what a black hole is.

In this cosmic bar graph activity, students solve 2 problems using given bar graphs that plot the number of galaxies vs. the galaxy type and the number of gamma-ray bursts vs. the burst classification. Students find the fraction of...

Skim the surface of the earth with this brief, compact, summary of outer space. The sun, stars, galaxies, planets, and phases of the moon can be found in this all-in-one resource. Seventh graders will enjoy these simple worksheets to do...

But isn't the Milky Way a candy bar? Lead a detailed discussion on the complex topic of our solar system and the Milky Way Galaxy as the class explores stellar evolution, structure, and investigates the relationship between luminosity...

Students compare specific similarities and differences among galaxies by examining features visible in the photographs, identify types of features found in galaxies, and discuss what the classification groups they devised might tell them...

Many people know that fiber optics are used in delivering the Internet, but are surprised to learn they are also used in astronomy. Scholars explore light, reflection, and fiber optics through hands-on activities. They discuss methods of...

It takes 225 million years for our sun to travel around the galaxy. The presentation covers astronomical units, light years, telescopes, types of stars, the life cycle of a star, and types of galaxies. This is the last lesson in a...

Students use the provided website to classify galaxies after exploring information about elliptical, spiral, lenticular, and irregular galaxies and using the Hubble Tuning Fork.

Students practice skills used in scientific investigation while studying the three main types of galaxies. Students identify Earth as part of Milky Way galaxy, the parts of galaxies, and the types of galaxies, as well as classify...
