How Many Monarchs Can You Count in One Minute?
An Online Challenge Activity
(Back to Introduction)

• Count monarchs flying across each practice window for one minute.
• Calculate the migration rate using standard units of measurement.
• Compare your results to find which shows the strongest migration.
Count: Click the links below to count the flying monarchs!
 Window #1 Window #2 How many monarchs did you count in Practice Window #1? _________________ How many monarchs did you count in Practice Window #2? ______________________
Calculate: What is the migration rate?

Take the results from your practice counts above and find the migration rates, in monarchs per minute and monarchs per hour:

Window #1: ____ monarchs/minute = ___ monarchs/hour

Window #2: ____ monarchs/minute = ___ monarchs/hour

Compare: Where was the migration strongest?
• How would you report your findings on the migration rates in each window? Try writing scientific statements about the migration rates in this test using standard units of measurement: monarchs per minute and monarchs per hour.
• How did this activity help you prepare for observing monarchs and reporting your sightings to Journey North?
