Concept:Inquiry-based learning uses direct interaction to explore topics like industrial development.
Explanation:Activity A lets students interview workers about minimum wages, giving firsthand insight into employment and wages in industry.
Activity B asks students to observe land use changes, providing direct experience of how industries affect land patterns.
