Why is This Place So Special for Monarchs?
(Slideshow Overview)

 

Overview

This slideshow tells a story of discovery. Students learn that scientists did not know about the monarch's winter home in Mexico until 1975. Scientists discovered that monarchs migrate each fall to an astonishingly small region in Mexico that measures only 73 miles wide. Within it, the monarchs gather on only 12 mountain sanctuaries where they cluster in colonies by the tens of millions. These mountain sanctuaries provide the unique conditions monarchs need to survive the winter, from November until mid-March. Use this story as a springboard to explore the essential question:

Essential Question

Suggested Activities

Identify Scientists' Questions
Encourage students to identify the questions scientists had when they discovered the monarch's winter home in Mexico. What was surprising about the place? What are the conditions like? (forest habitat, cold temperatures, high elevation, mountain landscape, few flowers/little food, located in central Mexico, unique microclimate).

Explore Rare Habitat
Use Journal Page #1 to explore a map of Mexico and see how rare the monarch's winter habitat is. The monarch sanctuaries are in a rare type of forest called the oyamel fir forest. Ask, Why is it important to conserve the oyamel forest in Mexico? Challenge students to collect different kinds of maps to learn about the unique characteristics of the monarch’s winter habitat.

Measure and Compare
Use Journal Page #2 to explore the size of the monarch overwintering region. Measure distances and compare on a local map for a personal connection. Consider risks and benefits. Ask, What are the benefits and risks of having so many monarchs overwinter in one small region?

Learn about "microclimates" by finding examples in your surroundings. (Brainstorm what this word might mean. Try breaking it down into the words "micro" and "climate.") Have students take temperature readings in different locations on your school grounds. The areas you explore may have different microclimates. Differences in temperature, humidity, wind, and exposure to the sun are factors that can cause microclimate conditions. (See sample map.)

What is a Microclimate?

A microclimate is the climate of a local area where climate conditions differ from the surrounding, general area.

Writing Prompt: Discuss this statement: "The fact that the monarchs can survive for five winter months in Mexico is as amazing as the monarch's spectacular migration." Compare facts about fall monarch migration and the monarch's overwintering season in Mexico.
