Weighing the Evidence for a Mass Extinction: In the Ocean
Description
Student Learning Targets
- Measure and compare irregularly shaped objects to identify patterns in rock layers above and below the K-T boundary that can be correlated to a dependent variable.
- Collect and categorize objects from multiple observations, converting scaled images and making direct size comparisons between specimens.
- Analyze information contained in graphs.
