Give your earth science students a focused look at galactic collisions with ninety questions built for real classroom use, whether you are starting a new unit or reviewing before a test.
Sample questions include "What phenomenon often occurs in the center of merging galaxies?", "What is often observed in the infrared spectrum of merging galaxies?", and "What can be inferred from the presence of young stellar populations in interacting galaxies?"
Because the three worksheets share the same content in three different formats, you can spread them across the week: one for diagnosis, one for practice, and one for assessment, without repeating a single question.
This set is part of a NGSS aligned earth science unit. The unit also covers Types of Galaxies and Their, Structure of the Milky Way, Star Formation and Nebulae, Hertzsprung Russell Diagram, Stellar Life Cycles Low, and Galactic Rotation and Dark, all in the same three worksheet format, so your classroom routine stays familiar while the topic changes.
Suitable for Grade 9-12 earth science classes, and for review at any point in the school year. This set is aligned to NGSS standard HS-ESS1-3.
