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...

In this cosmic bar graph worksheet, learners 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...

In this galaxy learning exercise, students use a website to research the 3 types of galaxies and how Edwin Hubble classified galaxies. This learning exercise has 1 graphic organizer and 4 fill in the blank questions.

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...

Reach for the stars with a fun space science video! Viewers learn about the different types of stars in the galaxy, as well as the ways to organize and classify them based on color and age.

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...

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

Eighth graders take a quiz to review the different objects in space. As a class, they define terms related to galaxies. In groups, they make a model of the Milky Way galaxy using materials provided to them by their teacher. To end the...

In this classifying dinosaurs learning exercise, students follow directions to make a classification chart for each kind of dinosaur. Students follow 16 sets of directions.

Students simulate stars in the Milky Way Galaxy using newspaper prints. In this space science lesson plan, students compare the number of 'stars' on their page to familiar things. They calculate how many pages they need to have the same...
