VA SEA 2017 Lesson Plans
Best suited for advanced high school students, this lesson offers an example of how a biologist uses morphometrics to test hypotheses about sexual selection and evolution in snapping shrimp. Students use software (ImageJ) to measure carapace and claws of two shrimp species with contrasting lifestyles. Students can take measurements themselves using ImageJ, and then analyze using Excel.
