Explanation

A school can be described as:

1. A social laboratory for children – It serves as a space where children experiment with social interactions, learn cooperation, and develop interpersonal skills.
2. A model social centre – It represents a microcosm of society, teaching norms, values, and civic responsibilities.
3. Responsible for awakening the sense of collective life – It fosters teamwork, community spirit, and an understanding of shared responsibilities.

Thus, a school encompasses all these roles in shaping individuals for societal participation.
