Looking Around 2 — About Me / Clothes We Wear. Sunrise routines and seasonal clothing in Looking Around 2 depend on the Sun's light and heat.
What you'll learn
- The Sun gives us light and heat.
- Day and night — Sun appears to move across sky.
- Never look directly at the Sun.
Key concepts
Verbal: The Sun gives light and heat. It appears to rise in the east and set in the west.
Symbolic: Earth rotates → day (Sun side) / night (away from Sun). Never stare at the Sun.
Level 1 — Sun's gifts
Light to see, heat to warm Earth, helps plants grow.
Level 1 — Day and night
Earth spins — Sun side = day, other side = night.
Level 1 — Morning to evening
Sun rises in east, sets in west (appears to — Earth rotates).
Level 2 — Seasons (intro)
Summer sun feels stronger; winter sun lower and milder.
Level 2 — India
Surya namaskar at sunrise; drying papads and pickles in sun.
Worked example
Why do we wear lighter clothes in hot sunny weather?
Step 1 — Sun gives strong **heat** in summer.
Step 2 — Body needs to stay cool.
Step 3 — Light cotton clothes help.
Answer: Sun's heat — lighter clothes keep us cooler.
Common mistakes
| Mistake | Why | Fix |
|---|---|---|
| Sun moves around Earth | Appearance | Earth rotates (Class 2 simplified) |
| Safe to stare at Sun | Dangerous | Never look directly |
| Sun shines at night | Day/night cycle | Your side turned away from Sun |
Quick check
- What two things does the Sun give us?
- East or west — where does sun rise?
- Why hang clothes outside on sunny day?
Stretch: Why do farmers dry grain in the sun before storing? Name two Sun gifts besides drying.
Revision tip: Notice sunrise direction once this week — link morning light to which side of your home is east.

Interactive Exploration Suggestions (Drishti Live Worlds)
- Use the platform-native live simulation or PhET-style tool for this topic (number line, Venn, physics playground, molecule builder, sensor dashboard, etc.).
- Mirror / body / home activity: physically do the concept (count objects, measure, role-play) and photograph or describe for portfolio.
- Voice or text reflection with AI Mentor: explain the concept to a younger student or family member.
AI Mentor Prompts (Socratic, Board-Adaptive)
- "Explain this concept to a Class 6 student using one real example from an Indian home, school, market, or festival."
- "What is one common mistake students make here, and how would you catch yourself making it?"
- Stretch: "How does this connect to coding, robotics, money, health, environment, or a future career?"
Gamification, Portfolio & Parent Visibility
- Complete the core practice + one extension activity (photo, table, short reflection, or mini-project) for base XP + topic badge.
- 5-7 day streak or family discussion note = multiplier + visible artifact in parent/principal dashboard.
- Best real-world application stories (anonymised) featured on class or national leaderboard.
Robotics, STEM & Future Skills Bridges
- One hands-on project or measurement using the Drishti kit or household items that makes the concept physical.
- Direct link to at least one Future Skill track (Money Management, Green Tech, Cyber Defenders, Micro-Entrepreneurship, AI Mastery, Sustainable Living, Personality Development).
- Coding extension where relevant (simple script, simulation, or data logging).
