Filtering Water

Looking Around 2 — Water. Cleaning muddy water with cloth filters is a hands-on activity in the Water chapter.

• Dirty water has mud and bits we can see.
• Filtering removes insoluble dirt through cloth or filter.
• Filtered water may still need boiling.

Verbal: Filtering traps visible dirt — mud and leaves stay on the cloth; clearer water passes through.

Symbolic: Settle → pour → filter. Removes: mud, sand. May NOT remove: tiny germs (need boiling).

Level 1 — What is filtering?

Pass water through cloth, paper, or sand filter — dirt stays behind.

Level 1 — Home methods

Muslin cloth over vessel; matka water with candle filter (intro).

Level 1 — What filtering removes

Mud, sand, leaves — visible dirt.

Level 2 — What it may NOT remove

Tiny germs (need boiling or UV).

Level 2 — India

Jal Jeevan Mission — clean tap water; village pond water filtered at home.

How would you clean muddy water from a puddle?

Step 1 — Let mud **settle** at bottom.
Step 2 — Pour top water through **clean cloth**.
Step 3 — Cloth traps mud particles.
Answer: Settle, then filter through cloth.

• What does a filter catch?
• Filter or boil — which kills germs?
• Name material used to filter at home.

Stretch: After filtering pond water, is it safe to drink? What extra step would Amma add?

Revision tip: Try a home demo: mix mud in water, settle, filter through muslin — draw before/after sketches.

• 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.

• "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?"

• 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.

• 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).

This material emphasises experiential "learning by doing", competency (apply/create/analyse), vocational exposure, critical thinking, and multidisciplinary connections. Designed to feed live worlds, AI Mentor (with memory), gamification, robotics, parent analytics, and future skills — not just exam prep.

Portfolio Evidence Idea: Your photo/table/reflection/project + one sentence on "How this helps me in real life or a possible future path."
