Calculating Iridium Fallout from an Asteroid Impact

This Calculating Iridium Fallout from an Asteroid Impact activity & project also includes:

Should we be afraid of a large asteroid impact on Earth today? Young scientists estimate the size and composition of an asteroid similar to the one that caused the K-T mass extinction. They apply algebraic formulas to answer questions before having a discussion about the assumptions and conclusions the data help them reach.

Instructional Ideas

• Pre-teach parts per notation before working through the rest of the lesson
Classroom Considerations

• Relies on prior knowledge of algebra, solving for volume and surface area of spheres, scientific notation, metric units, and density
• Lesson works as an extension to the short film The Day the Mesozoic Died, but stands alone if needed
Pros

• Provides two versions, one with guided calculations and the other without
• Designed to connect math and science concepts

• None
