Class 5 EVS (Our Wondrous World) Chapter 7, Energy — How Things Work, opens Unit 4 (Things Around Us) by exploring what energy is (movement, heat, light, sound), sources of energy (food, fuels, electricity, Sun, wind, water), and why clean renewable energy is vital for the future.
What Class 5 EVS Chapter 7 Covers
What is Energy & Everyday Sources (Food, Fuel, Sun, Wind, Water) identifies energy in action—moving, heating, lighting and making sound (Activities 1–3)—and compares energy from food for living beings, fuels (petrol, diesel, LPG, coal, wood) for vehicles and stoves, and natural solar, wind (firki/windmills) and flowing water energy.
Electricity, Clean Energy & Conserving Energy traces how electricity powers homes without smoke, how solar panels (like Cochin International Airport, the world’s first fully solar-powered airport), wind farms and hydro-wheels generate clean electricity, and lists practical ways to save energy at home and school.
