English Notes Chapter 3.4 – At the Science Fair Class 6 Maharashtra Board

Notes For All Chapters – English Class 6

1. Introduction

This chapter is about two science experiments:

• Marbling – A way to make beautiful paper designs using oil paints and water.
• Magic Watering Can – A special watering can that controls water flow using air pressure.

2. What is Marbling?

Marbling is a method of decorating paper with colorful designs.
It works because oil does not mix with water.

Things Needed for Marbling:

• A bucket of water
• Oil paints (red, blue, yellow, etc.)
• Turpentine or kerosene (to mix with paints)
• A brush
• White paper

Steps to Do Marbling:

Fill a bucket three-fourths with water.
Mix oil paints with turpentine or kerosene.
Sprinkle the colors on the water using a brush.
Use the brush to twirl the colors into patterns.
Gently place a sheet of paper on the water.
Lift the paper and let it dry.

Why It Works?

• Oil floats on water and forms colorful patterns.
• The paper picks up the colors, creating beautiful designs.

3. What is the Magic Watering Can?

A special watering can that controls water flow using air pressure.

Things Needed to Make It:

• An empty tin with a lid
• A nail and hammer

Steps to Make a Magic Watering Can:

• Take an empty tin.
• Use a nail and hammer to make a hole at the bottom.
• Make many small holes in the lid.
• Be careful while using the hammer.
• Your magic watering can is ready!

How to Use the Magic Watering Can:

• Cover the bottom hole with your finger.
• Fill the can with water.
• Put the lid on and turn it upside down.
• Remove your finger – water will start falling like a shower.
• Cover the hole again – the water stops.

Why It Works?

• Air pressure controls the flow of water.
• When you block the hole, air cannot enter, so water stops flowing.
• When you open the hole, air enters and pushes the water out.

4. Important Words & Meanings

Marbling – A technique to create beautiful designs on paper.
Turpentine/Kerosene – A liquid used to thin oil paints.
Air Pressure – The force of air that controls water flow.
Experiment – A science activity to learn new things.

5. Lessons from the Chapter

• Science can be fun and creative!
• Marbling shows how oil and water do not mix.
• The magic watering can teaches us about air pressure.
• We should try simple science experiments to learn more.
