Wood platforms to float within the containers.
Paper towels to cover frogs when not being observed. During this exercise you will determine the nervous system location of various reflexes in a frog. In brief, the behavior of a normal frog will be observed and then portions of the nervous system will be sequentially destroyed. If a behavior is still observed in animals with a lesioned system, then the portion that was destroyed does not have the nervous pathways for the reflex. Work in groups of three or four and read through the entire procedure before beginning.
