Separation

• Separate mixtures because parts keep different properties.
• Methods: handpicking, sieving, filtering, evaporation.
• Choose method by size, solubility, and state.
• Looking Around 3 — cleaning rice, filtering water.

Level 1 — Core idea

Verbal: Pick stones from rice by hand — stones bigger and harder to see.

Symbolic: Separate without changing identity of parts.

Visual: Sieve: small flour through, big bran stays.

Level 2 — Going deeper

Evaporation: salt from salt water — water evaporates, salt left. Filter: mud from muddy water with paper/cloth.

NCERT anchor

NCERT Looking Around 3, Chapter 7 water filtering and Chapter 6 rice cleaning match these methods. Always ask adult for heat steps.

How get salt back from salt water?

Step 1 — Heat dish of salt water (**evaporation**)
Step 2 — Water becomes vapour; **salt remains**
Step 3 — Adult supervision for heat ✓

Separate pebbles from sand.

Step 1 — Pebbles **larger** than sand grains
Step 2 — Use **sieve** — sand falls through, pebbles stay
Answer: **Sieving**

• Method for stones in dal?
• How separate mud from water?
• What stays after salt water evaporates?
• Stretch: Tea leaves from tea — which method?

Revision tip: Flowchart: big bits? → handpick/sieve. Dissolved? → evaporation. Muddy? → filter.

• 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.
