Background of the Study
Biology as a subject of life and living things needs to taught not just theoretically but practically for it be functional and to lay the base foundation needed for science and technological development.
Erickson (2005) noted that for a science teaching and learning to be effective every student must be given an opportunity to handle the materials of science and experience science personally. Biology is the study of life and living things, so a resourceful teacher does not have any reason for teaching biology, supporting him Asiabaka(2010:266) education is the key to national development, it provides the intellectual capability needed by man to enhance the human and material resource for scientific and technological advancement.
