This set of professional development videos introduces teachers to Journey North, an Internet-based program that engages students in investigations of wildlife migration and seasonal change. Each year, thousands of students and their teachers across North America come together to experience the annual cycle through observation, inquiry, research, and the sharing of data. The video programs show how to use the project in the classroom and feature examples of 2nd- through 7th-grade teachers and their students engaging in some of the most popular Journey North investigations.
