students will measure objects in their environment to
compare to given lengths.
- Put the students in pairs
and give each pair a string cut to 5 feet and a string
cut to 5 inches.
- Discuss with the students
that the long piece of string is similar to the length
of some megabat wingspans and the short string is
similar to some types of microbat wingspans.
- Pass out the Measuring
with Bat Wings Worksheet.
- Have the students complete
the worksheets by moving about the room and measuring
classroom items in comparison to their strings.
- Count by 5's with
questions such as "What would the wingspan be of
3 megabats tip to tip?" (With their
wingspans being 5 feet.)
- Research and find out the
average wingspan of different kinds of bats. Cut
strips of paper, or string, to those lengths, label
them and display them in the classroom or hallway.
- Measure how many inches
are in 5 feet. Ask how much longer a megabat's
wingspan is than a microbat's.
