Give your earth science students a focused look at gravity in galaxies with ninety questions built for real classroom use, whether you are starting a new unit or reviewing before a test.
Students will answer questions such as "What happens to the orbital speed of stars as they move away from the galactic center?", "Why do some stars in a galaxy move faster than expected based on visible mass?", and "What is the significance of the rotation curve of a galaxy?"
All three worksheets cover the same topic in different question styles. That means you can use one as a pretest, another for practice or homework, and the third as a follow up quiz, without students ever seeing the same question twice.
This set is part of a NGSS aligned earth science unit. The unit also covers What is Gravity, Modeling Orbits, Gravity and Moons, Gravity and Inertia in Space, Changing Gravity Mass, and Gravity Fields Visualization, all in the same three worksheet format, so your classroom routine stays familiar while the topic changes.
Suitable for Grade 6-8 earth science classes, and for review at any point in the school year. This set is aligned to NGSS standard MS-ESS1-2.
