In the teaching and learning of science, some science process skills are needed and this article will briefly speak of four:
(1) OBSERVATION:- Just as detectives look for clues to murder weapons, motive of crimes and criminals; a student must possess trained skills for observation using the sense of sight, touch, smell, hear, taste, etc. According to Hodgson and Scanlon (1983) "the powers of observation can be learnt..."
(2) CLASSIFICATION:- This is another skill of a scientist or someone learning to become a scientist. This ability requires a very deep understanding of how to sort things in accordance with their types or properties using genres, habits, sizes, colors, ages, genders, etc.
(3) COMMUNICATION:- Whether written, spoken, coding, or other means; scientific researches and outcomes are brought to light through communication. Any student of science must be skilled in talking, writing, drawing, charting, plotting; for the sole aim of scientific developments.
(4) PREDICTION:- One of the skills that places science ahead of other disciplines is prediction. A good scientist should be able to guess correctly what happens when a glowing splint of wood is introduced into a glass jar full of gas. The wood splint will definitely burst into flame.
