The wing has two thin layers of flexible skin stretched between these fingers. The skin is so thin that you can almost see through it. Suggested Procedure Facilitate a class discussion about how a bat's wing is like a human hand to assess what students already know. Let them share ideas. Show students the bat wing pattern.
Bats have many more bones in their wings than the pattern shows.
Because a bat is symmetrical, it will usually have the same number of bones on both sides of the body at approximately the same location. Make copies of the bat wing pattern. Give each student a copy of the bat wing pattern, a sheet of black or brown construction paper, a sheet of white or manila construction paper, scissors and glue. Have students cut out wings and trace them twice onto the construction paper. Instruct students to cut out the two wings.
