AN INVESTIGATION ON SAFETY PROCEDURE IN SCIENCE LABORATORY ( EDUCATION PROJECT TOPICS AND MATERIALS)
This research study was carried out to investigate the safety procedures in science laboratories in some selected secondary school in Abeokuta Ogun State. There is doubt that school science laboratories are remarkably safe places to teach and learn. There are, however reason for believing that the present level of safety risk might rise rather than fall. If most accident can be prevented by suitable knowledge and adequate planning. The careful and thorough organisation which is of particular importance in teaching. Science at school level demands a knowledge of the likely and of possible hazards in each teaching situation. It is hope that these lessons and in advising pupils, thereby encouraging the development of necessary safety skill, and attitudes in those engaged in experimental science.
1.1 BACKGROUND TO THE STUDY
Science can be defined as an attempt by human beings to organize their experience about nature into meaningful system of explanation. It can also be regarded as organization of reasonable variable sense experiences of man about natural and artificial occurrences in his environment, it is through science that regularities of nature are predicted, described and explained. Science cannot be said to be broad-based, unless it is postulated on the important pillars of experimentation, out-door work and above all, development of project. Apart from creating opportunities of probing the theoretical concepts taught in the classroom, practical work also inculcates scientific skills, ethics and regulatory principal of science.
Science is activity, and effective science learning is by doing. For a child to master the art of writing for example, he must be given opportunities to write as often as possible. Similarly, science learning demands that a teacher should create varied opportunities for students to engage in “doing” activities that enable them to make sense of the world around them, make new discoveries, solve interesting problems, and develop skills.
A laboratory is an environment for acquisition of skills and other scientific learning; it could be comprehensive where more than a trade is taught, it may be a building room or outside room designed for scientific research or for the teaching of practical science. Bajah (1975) sees a laboratory as an activity area in which role learning gives way to a combination of complex mix of cognitive, affective and psychomotor domains in learning with the sense of sight, feeling, smelling and doing playing dormant roles.
A pure science laboratory are classified based on the act of sciencing to be learnt. Generally, laboratory are infrastructure whose goal are to promote human learning and efficiency for a definite goal therefore an expert must oversee the construction, sitting and equipping of these building to enhance safety.
