Suction

Class: 5Ã¨me.

Lesson: La locomotion chez les insectes. Le tÃ©nia

Rationale: Demonstrate suction when discussing the locomotion of flies and the head structure of tÃ©nia by attaching a small tube of rubber to the arm of a student.

Materials:

bulb from an eye dropper (science kit)

a short piece (~2 cm) of hose (the larger diameter hose the better)

a student's arm
