Every individual has his own psychological environment, in which he lives. Kurt Lewin has used the term ‘life space’ for explaining the psychological environment. The psychological environment enables us to understand the personality of an individual.

The ‘Framework’ of 1975 provided general guidelines and instructional objectives only up-to-the secondary stage. The reasonability of identifying aims and objectives of science teaching and the development of the syllabi and textbooks for different disciplines at the senior secondary stage was given to the curriculum developers.

Every learner is unique means that no two learners are alike in their abilities, interests and talents. Individual learners differ from each other in rate of development. Learners have different strategies, approaches and capabilities for learning that are a function of prior experience and heredity.

Project is an activity willingly undertaken by the pupils for the solution of a felt problem. Steps of project method are- providing a situation, choosing, purposing, teacher’s role, freedom and utility, evaluation and recording.

The best way, especially at primary level, to address the learning difficulties of students is to use a variety of teaching methods suited to the disability. Individuals with intellectual disabilities (ID, formerly mental retardation) benefit from the same teaching strategies used to teach people with other learning challenges. This includes learning disabilities, attention-deficit/hyperactivity disorder, and autism. One such strategy is to break down learning tasks into small steps. 
A second strategy is to modify the teaching approach. Third, people with ID do best in learning environments where visual aids are used. A fourth teaching strategy is to provide direct and immediate feedback.

Because students experience are the base of knowledge construction.Constructivism emphasizes the importance of the knowledge, beliefs, and skills an individual brings to the experience of learning.

The methodology of teaching-learning of environmental concepts, problems and issues is not completely new. Many of the variety of methods used in this case are practically the same as those used in other subject areas. However, since objectives of environmental education demand more challenging learning outcomes, the existing classroom practices need to be supplemented with more innovative and participatory techniques. Merits of problem solving method in environmental education is goal oriented method, selectivity, reative method, etc.

Science is one and at the primary stage, science and social sciences were to be taught as a single subject: ‘Environmental Studies’. Different disciplines of science are only tentative compartmentalization of the subject to facilitate the study of its different aspects; the integrated curriculum should highlight this unified nature of science, 

* curriculum should attempt to link teaching of scientific principles with daily life experiences of the learners, 

* science curriculum should stress more on the processes of science than the product
