This paper looks at the extraction of oil from African Breadfruit (Treculia Africana) seeds using different solvents. The seeds were crushed into powder and the oil was extracted from the powder. The method of extraction employed was soxhlet (Solvent extraction method). The solvents used were Acetone, N-hexane, Ethanol, Petroleum Ether and Diethyl ether. The amount of oil extracted by each solvent was recorded and the % yield was calculated.Conc. Diethyl ether had the highest % yield of 15.02 while Ethanol had the lowest % yield of 0.2. Also there was a significant difference in the yield of oil extracted byDiethyl ether and Conc. Diethyl ether showing that the concentration of a particular solvent has an effect on the quantity of oil yield.

All learning activities are geared towards not what the teacher is going to teach, but what the outcome of that teaching should be, what the learner is supposed to do, and at what level. Education plays a main role in shaping the learner to be a better, responsible citizen and an active member of the society. It provides the ladder for achieving success in life as well as constructive utilization of acquired skills and knowledge. Critical thinking should be taught in schools so that students may learn to think for themselves and make their own choices, as well as to prepare them for the difficulties of adult life and to help them live a full and happy life that includes critical thinking. The instructor is at the core of traditional education, which does not foster inventiveness or originality. Critical thinking approach will erase traditional teaching deficiencies and will breed professional competence, cognitive transformation, and self-confidence. Various strategies that can foster the development of critical thinking across disciplines in education have been explored by researchers recently, and despite the acknowledged importance, critical thinking skills are frequently not taught explicitly; teachers are not intentional in the teaching and learning process, the assumption being that students will learn from the implicit values buried deep within our teaching philosophies. It is essential that teachers understand critical thinking processes and employ instructional activities to build these processes to teach critical thinking abilities. Researching critical thinking is a continuous process since it is a contentious and extensive topic in terms of definition and progress.
