According to N.C.F. 2005 in the upper primary stage science curriculum, which of the following is recommended? a. Concepts should be linked to making sense of everyday experience. b. Concepts should be arrived at from activities/experiments. c. Concepts should be taught through disciplinary approach. d. Along with concepts, laws and theories need to be introduced

NCF 2005 recommends that at the upper primary stage, science be taught through engagement with everyday experiences and through activities/experiments to construct concepts. The disciplinary approach (separating physics, chemistry, biology) is recommended only at the secondary stage. Introducing formal laws and theories also belongs to the secondary stage. Hence only statements a and b are recommended at the upper primary stage.
