Mnemonics: The Wonderful World of Science | Science for Class 6 PDF Download

1. Science and Curiosity

Mnemonic: Curious Minds Explore, Ask, Discover

• C – Curiosity: Like babies who touch and observe everything, curiosity is the starting point of science.
• M – Method of thinking: Science is described as a way of thinking and observing to understand the world.
• E – Explore: The process of exploration helps us discover how things work.
• A – Ask questions: Science begins with asking questions like “Why does this happen?”
• D – Discover: Through questioning and exploration, we make discoveries.

2. Science is Everywhere

Mnemonic: Stars, Flowers, Crops – Science Helps All

• S – Stars: Science explains that stars shine because of internal reactions.
• F – Flowers: Flowers bloom due to changes in light and temperature.
• C – Crops: Understanding how plants grow helps farmers produce better crops.
• S – Solves mysteries: Science helps solve everyday mysteries in nature.
• H – Helps us understand: It gives clarity to how the natural world works.
• A – Answers questions: It helps us answer “why” and “how” things happen.

3. Exploring Earth

Mnemonic: Plants And Ecosystems Thrive

• P – Plants: A seed becomes a plant with water, sunlight, and soil nutrients.
• A – Animals: A caterpillar turning into a butterfly is explained by metamorphosis.
• E – Ecosystems: Forests, oceans, and deserts are examples of different ecosystems.
• T – Thrive: These systems support life by providing food, shelter, and oxygen.

4. Importance of Food

Mnemonic: Food Gives Energy And Growth

• F – Food: A basic need for all living beings.
• G – Gives: It provides fuel for daily activities.
• E – Energy: Helps our body perform tasks, like thinking and moving.
• G – Growth: Supports body development and health, especially in children.

5. Importance of Water

Mnemonic: Water Flows In Three Forms

• W – Water: Essential for life and fun (e.g., jumping in puddles).
• F – Freezes: At 0°C, water becomes solid ice.
• I – Ice (solid): One of the forms water can take.
• T – Turns to steam: Boiling at 100°C changes water into gas (steam).
• F – Forms: Solid (ice), Liquid (water), Gas (steam) — all seen in daily life.

6. Properties of Materials Around Us

Mnemonic: “Metals Shine, Plastics Bend, Papers Tear”

• Metals → Metal properties (Shiny, used in keys, recyclable)
• Shine → (Reinforces metal’s appearance)
• Plastics → Plastic properties (Flexible, used in rulers, recyclable)
• Bend → (Reinforces plastic’s flexibility)
• Papers → Paper properties (Tearable, used in books, recyclable)
• Tear → (Reinforces paper’s fragility)

7. Scientific Method Steps

Mnemonic: Old Ants Hate Testing Rotten Cookies

• O – Observe: Look closely at what’s happening (e.g., plant growing toward light).
• A – Ask a question: “Why does the plant grow that way?”
• H – Hypothesis: A smart guess — maybe it grows to get more light.
• T – Test it: Set up an experiment with different light conditions.
• R – Results: Check if plants in light grew toward it.
• C – Conclusion: Decide whether your guess was right or wrong.

8. Example of Scientific Method (Pen)

Mnemonic: Observing Quietly Helps Test Correctly

• O – Observe: The pen isn’t writing.
• Q – Question: Why did it stop?
• H – Hypothesis: Maybe the ink is finished.
• T – Test it: Check the refill.
• C – Conclusion: If ink is empty, you’re right. If not, guess again.

9. Key Points Summary

Mnemonic: Cool Scientists Make Smart Choices Together

• C – Curiosity: The foundation of science and discoveries.
• S – Science = thinking & observing: Science is a way to observe and think critically.
• M – Method (scientific): A structured process to find answers.
• S – Steps: Observe, Ask, Hypothesize, Test, Analyze, Conclude.
• C – Collaboration: Scientists work together to learn and grow.
• T – Teamwork: Essential in making scientific breakthroughs.
