- B. Build an awareness that science learning is tied to social and environmental responsibility
- C. Suggest that nature does not change
- D. Replace science with civics
Q11. A Class 7 group repeats an experiment they think they already understand. The chapter would say this is
- A. A waste of time, since the answer is known
- B. Useful only for marks, not learning
