Thinking Like a Scientist: Can a Butterfly Fly Across the Atlantic
Ocean?
As your students pose their own ideas about this puzzle
— and look at fifth graders' theories — they will begin
to think like scientists. Remind them that scientists are not even
sure of the answer!
Once
they've pondered how the monarchs may have gotten there, invite
them to look at the facts and state the case for one of the theories.
Here are some suggestions:
- Before
having students review the Look
at the Facts page, pass out the Weigh
the Evidence handout.
- To
simplify, you can have the class vote on one theory, and read
the facts with that in mind. (Or you could have small groups each
consider one theory.)
- To
simplify, you can also select and have students ponder just a
few facts from the list.
- Once
students have found evidence to support or refute theories, have
a classroom debate! Small groups can "state the case"
for different theories.
- Report
your ideas to us; we'd love to hear your thoughts! Contact Journey
North >>
- If
you have older students, share this example of how one scientist
layed out an argument to defend his theory. >>
