Q6. Picture-based (VSAQ). The lesson shows people keeping cattle on the ground floor in cold regions. What benefit does it provide to the rooms above?
Q7. Observation (VSAQ). Why do we feel active and ready to play after eating, according to the class discussion in the chapter?
Q8. Picture-based (VSAQ). Diyas experiment: Which diya burns longer—one with only wick or one with wick and oil? What acts as fuel?
Q9. Observation (SAQ). List two things in a home/classroom that run on electricity and what they mainly provide (light/sound/heat/movement/cooling).
Q10. Observation (VSAQ). Which bulb type saves more energy for the same light—LED or an old incandescent bulb?

Q12. Match (Match the following). A. Balloon release — B. Rubber band guitar — C. Sun‑warmed cup — D. Water wheel. Options: 1) Heat energy, 2) Movement from air, 3) Sound energy, 4) Movement from water flow.
Q13. Identify (MCQ). Which is NOT a clean source of electricity?
a) Coal b) Sunlight (solar) c) Wind d) Flowing water (hydro)
Q14. Fill in the blanks (VSAQ). Energy is what makes things _____, _____, produce _____, do work and change _____.
Q15. Sort (SAQ). Put the following under the correct headings: “Needs electricity” or “Does not need electricity”. Fan, Solar dryer, Manual hand pump, LED lamp, Candle.
Q16. Identify (VSAQ). Which household fuel creates smoke and pollution when burnt and should be used carefully—LPG or firewood/coal?
Q17. Match (Match the following). A. LED bulb — B. Thick walls & small windows (traditional homes) — C. Battery — D. Pinwheel. Options: 1) Energy-efficient lighting, 2) Keeps home cool/warm naturally, 3) Stored energy, 4) Uses wind to move.
Q18. MCQ. Which safety action is correct?
a) Touching sockets with pens
b) Playing near transformers
c) Reporting broken wires to an adult
d) Fixing live wires by oneself
Q19. Fill in the blanks (VSAQ). Energy from the Sun, wind and water used to make electricity is called _____ energy (because it does not pollute).
Q20. Identify (SAQ). Name one device or activity from the chapter that shows each: heat energy, sound energy, and movement energy.
Competency 3: Discovery of Facts
Q21. Map-based (SAQ). On a map of India, mark any two regions with strong wind/solar/hydro potential (teacher may specify state examples). Briefly state why these are suitable.
Q22. Reasoning (SAQ). Why is using too much coal a problem, and what is a better alternative shown in the chapter’s activities/examples?
Q23. Inquiry (SAQ). If there were no electricity for a day, which daily tasks would be most affected at home and school? Give two examples for each place.
Q24. Application (SAQ). Suggest two ways to make a classroom more energy‑efficient using ideas from the lesson (buildings/devices/behavior).
Q25. LAQ. Explain how the “pinwheel,” “magnifying glass with sunlight,” and “water wheel” activities together show different ways energy makes things work without plugging anything in.
Q26. MCQ. Which change would most likely make the balloon air‑rocket move faster?
a) Less air in balloon
b) More air in balloon (tight inflation)
c) Heavier tape and straw
d) Bending the string sharply
Q27. Reasoning (SAQ). Why are batteries useful even when there is no direct electricity supply, and what word does the lesson use for such energy?
Q28. Inquiry (VSAQ). Write one example each where energy is used for: making sound, producing light, and cooling.
Q29. Application (SAQ). A class builds a small “clean energy home” model. Name two clean energy features they could show from the chapter.
Q30. LAQ. “Energy is everywhere.” Write a short paragraph describing how food, fuel, electricity, and clean natural sources together support daily life, with one example for each.
Activities
Activity 1: Energy Diary
For one day, list every time energy is used around you (food, electricity, fuel, Sun/wind/water). Classify each item by source and suggest one way to save energy for that item.
Activity 2: Classroom Energy Makeover
Draw a simple plan of your classroom showing windows/doors/lights/fans. Mark two changes that can reduce energy use (e.g., LED bulbs, using daylight, cross‑ventilation). Present how these help.
