Look at the region where the monarchs are now traveling:

• In which year were March temperatures there the warmest? the coldest?

Think about the pace and the direction of the migration:

• In which year was the migration the farthest ahead? the farthest behind?

• In which direction(s) did the migration move each year? Describe.

Why would it make sense for March temperatures and migration to be related? Explain your reasoning.

What other variables could be involved? List as many as you can.
