No Prep Plans: Cambridge Year 8 Science Earth & Space — Asteroids

No Prep Plans: Cambridge Year 8 Science Earth & Space — Asteroids

Bring asteroid science to life with an engaging, hands-on Asteroid Impact Investigation designed for Cambridge Year 8 Science / US Grade 7 and adaptable for Grades 6–8.

Students investigate asteroids, near-Earth objects, the Chicxulub asteroid impact, impact craters, and modern planetary defence. They then become planetary defence scientists as they conduct a controlled crater investigation, analyze their experimental data, and consider how scientists might protect Earth from a future asteroid threat.

Students Will:
✓ Explain what asteroids are and where they are found in our solar system
✓ Distinguish between the asteroid belt and near-Earth asteroids
✓ Investigate the Chicxulub impact and its connection to mass extinction
✓ Explore how asteroid impacts create craters and environmental effects
✓ Design and conduct a controlled asteroid impact model investigation
✓ Identify independent, dependent, and control variables
✓ Collect and analyze crater diameter and depth data
✓ Use claim, evidence, and reasoning to explain experimental results
✓ Evaluate the strengths and limitations of scientific models
✓ Explore NASA’s DART asteroid-deflection mission
✓ Consider why early detection is critical to planetary defence
✓ Design a response plan for a potential asteroid threat
