FOSS Planetary Science Investigation 5: Moon Craters (7 days)
Big Idea
Although active geological processes, such as plate tectonics and erosion, have destroyed or altered most of the very early rock record on Earth, other objects in the solar system, such as lunar rocks, asteroids, and meteorites, have changed little over billions of years. Studying these objects can provide information about Earth's formation and early history.(K-12 Framework Core Idea ESS1.C)
Essential Questions
Are lunar craters the products of volcanism or impacts? How can you design an investigation to get more evidence about impacts creating craters?
How does the size of a crater and its ray length vary based on the height of a dropped marble?
How does the size of the incoming object affect the size of the crater? the length of the rays?
Are lunar craters the result of volcanism or impact?
Part 6: Does Earth have craters?
Part 7: Where did the moon come from?
Standards

Science & Engineering Practices
Students will drop objects into flour to model crater formation:
  • Planning and Carrying Out Investigations
  • Developing and Using Models
  • Obtaining, Evaluating, and Communicating Information
  • Analyzing and Interpreting Data
Engaging in Argument from Evidence:  students use evidence to support their claim on crater size
Engaging in Argument from Evidence:  students cite specifc evidence to support their claim on crater formation
  • Developing and Using Models:  student use computer simulations to weigh evidence on origin of the Moon
  • Engaging in Argument from Evidence
Content/Core Ideas
  • Craters of various sizes result when meteoroids of various sizes hit the Moon's surface.
  • Craters can be categorized by size and physical characteristics.
  • The Earth has had similar impacts but have been erased by dynamic processes on Earth.
  • The moon was formed by a massive impact early in Earth's history.
Crosscutting Concepts
  • Cause and Effect
  • Scale, Proportion, and Quantity
  • Systems and System Models
