  • 8:30 – 9:00: Check-in and Networking
  • 9:00 – 9:15: Workshop Introduction
  • 9:15 – 10:30: The Biology of Skin: Explore how experimental work in zebrafish led to a better understanding of the gene SLC24A5, explore polygenic inheritance using a simple mathematical model, learn about the methods by which geneticists identify skin-color genes and estimate heritability, and learn how geneticists analyze genetic variations to trace an individual’s ancestry.
  • 10:40 – 12:00: Some Animals are More Equal Than Others and Trophic Cascades: Explore examples of what can happen when there are changes in the population size of one species in an ecosystem using the I2 Strategy to scaffold interpreting data.
  • 12:00 – 12:40: Lunch Break and Networking
  • 12:40 – 2:10: DNA Fingerprinting: Engags students by combining elephants, species conservation, and forensics to teach key biological concepts and science practices using actual cases.
  • 2:20 – 3:40: Elephants and More Elephants: We will explore a scientist at work about the Great Elephant Census, a Click and Learn on Survey Methods, and a hands-on activity on how scientists conduct sample counts.
  • 3:40 – 4:00: Afternoon Wrap-Up
