Harleen asked her teacher, “Why do roses have thorns?” What must be the pedagogy of an EVS teacher towards this curiosity?

The correct answer is: Ask her to observe animals eating plants with and without thorns.

Pedagogical Analysis:
Environmental Studies (EVS) pedagogy at the primary level emphasizes active learning, inquiry, and hands-on observation rather than direct rote transmission of facts.
When a student asks, “Why do roses have thorns?”, a constructivist teacher avoids simply giving the direct functional answer (e.g., "to protect themselves"). Instead, the teacher guides the student to construct their own understanding through observation and critical thinking.

Why this option is the most appropriate:
1. Promotes Observation and Inquiry: By observing animals interacting with plants that have thorns versus plants that do not, Harleen can notice that animals tend to eat the thornless plants while avoiding the thorny ones.
2. Active Knowledge Construction: This firsthand observation allows Harleen to figure out the protective function of thorns on her own, making the learning experience meaningful and memorable.
3. Development of Science Process Skills: Comparing two different scenarios (plants with thorns vs. plants without thorns) helps develop analytical skills such as comparison, hypothesis testing, and drawing conclusions from evidence.
