Help your students build real understanding of redshift and expanding through ninety questions that move from basic recognition to genuine reasoning about how the Earth works.
Among the ninety questions, students will see prompts such as "What does Hubble's constant represent?", "What happens to the light from a galaxy that is moving away from us?", and "In terms of redshift, what does a positive value indicate?"
Each worksheet reviews the same core ideas from a different angle. Use them across a week or unit so students see the material three times without it ever feeling repetitive.
This set is part of a NGSS aligned earth science unit. The unit also covers the Big Bang Theory, Cosmic Microwave Background, Formation of Galaxies, Evidence from Element, Tools of Cosmic Observation, and Dark Energy and Accelerated, 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-ESS1-2.
