High Can You SEE a Monarch?
It's hard to know how high monarchs fly during migration because it's so hard to observe them. They disappear from view!
Dr. Lincoln Brower wondered how high he could see a monarch in flight overhead. So he went outside in the big backyard of his college campus to find out.
What simple experiment could you design to answer this question? Have a class discussion. Then look at the pictures of Dr. Brower’s experiment.
