1. Magic with Metals: Rusting of Iron

Relevant Chapter: Chapter 4 - Materials: Metals and Non-Metals (CBSE Class 8)

Materials Needed:

• Iron nail
• Water
• Transparent glass
• Salt (optional)
• Oil (optional)

Steps:

• Place the iron nail in a glass of water.
• Let it sit for a few days.
• Observe the change in the nail.

Optional Variation: Add salt to speed up rusting or oil to slow it down.

Scientific Explanation:

Rusting is a chemical reaction between iron, water, and oxygen, forming iron oxide. This helps understand the corrosion process explained in your textbook.

Safety Tip:

Ensure younger children are supervised while handling sharp nails.

2. Invisible Ink Using Lemon Juice

Relevant Chapter: Chapter 5 - Coal and Petroleum (Carbon Compounds)

Materials Needed:

• Lemon juice
• Cotton bud or paintbrush
• White paper
• Iron or light bulb (heat source)

Steps:

• Dip the cotton bud in lemon juice and write on the paper.
• Let it dry.
• Gently heat the paper with a light bulb or iron.
• Watch the hidden message appear.

Scientific Explanation:

Lemon juice is an organic compound. When heated, it oxidizes and turns brown, demonstrating chemical change and properties of carbon compounds.

Safety Tip:

Do not let children handle the iron. Use adult supervision.

3. Balloon Blowing Up Itself (Acid-Base Reaction)

Relevant Chapter: Chapter 2 - Microorganisms: Friend and Foe

Materials Needed:

• Balloon
• Vinegar
• Baking soda
• Bottle
• Funnel

Steps:

• Fill the bottle with vinegar.
• Use a funnel to put baking soda inside the balloon.
• Fix the balloon over the bottle mouth.
• Tilt the balloon to drop the baking soda into the vinegar.

Scientific Explanation:

This is a classic acid-base reaction. Vinegar (acid) reacts with baking soda (base) to release carbon dioxide gas, which inflates the balloon.

Safety Tip:

Use appropriate quantities and avoid ingesting any chemicals.

4. Newton’s First Law with a Coin and a Card

Relevant Chapter: Chapter 11 - Force and Pressure

Materials Needed:

• Glass
• Cardboard strip
• Coin

Steps:

• Place the card over the mouth of the glass.
• Place the coin on the card.
• Flick the card horizontally.

Scientific Explanation:

The coin falls into the glass due to inertia, demonstrating Newton’s First Law of Motion.

Safety Tip:

Use lightweight, unbreakable glasses for safety.

5. Water Cycle in a Bag

Relevant Chapter: Chapter 18 - Pollution of Air and Water

Materials Needed:

• Ziplock bag
• Blue food colouring (optional)
• Water
• Permanent marker
• Tape

Steps:

• Add coloured water into the ziplock bag.
• Seal it and tape it to a sunny window.
• Watch condensation and evaporation over a few days.

Scientific Explanation:

This shows the water cycle — evaporation, condensation, and precipitation — in action.

Safety Tip:

Seal the bag tightly and place it out of children’s reach.
