Synopsis: Every year millions of monarch butterflies manage to find their way from hatching grounds in North America to wintering grounds in Mexico. These butterflies log up to 2,000 miles to arrive at their destination: a few fir tree-covered ridge tops in Mexico that none have ever been to. How do these lovely lepidoptera know where to go? How do other species migrate? What are modern threats to migrating species?

Questions
1. Why do monarch butterflies migrate?
2. What roles do the summering and wintering grounds play in their lifecycle? How do the seasons, food sources and reproduction fit into the picture?
3. What other species migrate?
4. What human activities can interfere with the migration of these various species? How can negative effects be minimized?
5. What are two unusual factors about the migration of the northern elephant seal in the North Pacific Ocean?
Lesson
Plans/Activities
1. Be a research assistant! Scientists at Monarch Watch rely on students to gather data and submit research reports about the migration of monarch butterflies in their area. Students use the data to assess research hypotheses. Instructions for monarch rearing are also included. This website offers projects appropriate for all grades.
2. Join an online research community! Even if monarchs don't fly through your back yard, you may still be able to gather and share migratory data for other species through The Journey North website. Students can follow online as various species complete their seasonal migrations, or participate in one of the site's ongoing projects. Periodic challenge questions will keep students on their toes. This website provides projects appropriate for all grades.
3. Get a green thumb for butterflies! Plant a butterfly garden at school. In addition to providing a great habitat (or snack) for butterflies, students may be able to observe butterflies pass through four life stages in the wild. This project is appropriate for all grades.
