No Prep Plans: Cambridge Year 8 Science — Galaxies

No Prep Plans: Cambridge Year 8 Science — Galaxies

Take students beyond our solar system with this engaging Galaxy Exploration Display lesson for Grades 6–8. Students investigate the Milky Way, galaxy types, enormous astronomical distances, galaxy collisions, and how modern telescopes are changing what we know about the universe.

Students then become a team of astronomers, using their research to build a Galaxy Exploration Display featuring real telescope images, galaxy classifications, scale comparisons, and a famous galaxy spotlight.

Students Will:
✓ Explain what galaxies are and what holds them together
✓ Identify and classify spiral, elliptical, and irregular galaxies
✓ Explore the structure and scale of the Milky Way
✓ Compare the Milky Way and Andromeda Galaxy
✓ Investigate how galaxies interact, collide, and merge
✓ Explore the large-scale cosmic web
✓ Examine discoveries from the James Webb Space Telescope
✓ Analyze how astronomers estimate the number of galaxies in the observable universe
✓ Communicate astronomical information through images, captions, diagrams, and scale models
