CONTENT OF THE LESSON

INTRODUCTION

Every day, we see different colours around us. The flowers in the garden, the green leaves on trees, the blue sky, colourful clothes, fruits, and traffic lights all have different colours. Colours make our environment beautiful and help us identify and describe objects easily.

When sunlight shines through tiny drops of rain, it forms a rainbow, which shows seven beautiful colours. We can also create new colours by mixing two or more colours together.

In this lesson, pupils will learn the meaning and types of colours, the colours of the rainbow, how new colours are produced by mixing colours, and the natural sources of colours found in our environment.

LESSON 1 – MEANING OF COLOURS

Colours are the different appearances of light that we see with our eyes. Colours make objects look different and help us identify and describe them.

Examples of colours include: red, blue, yellow, green, orange, purple, black, and white.

TYPES OF COLOURS

1. Primary Colours

Primary colours are the basic colours that cannot be produced by mixing other colours.

The three primary colours are:

• Red

• Blue

• Yellow

2. Secondary Colours

Secondary colours are formed by mixing two primary colours.

Examples of Secondary Colours are:

• Red + Yellow = Orange

• Yellow + Blue = Green

• Blue + Red = Purple (Violet)

3. Neutral Colours

Neutral colours are colours that are neither bright nor dull.

Examples of Natural Colours are:

• Black

• White

• Grey

IMPORTANCE OF COLOURS

• Colours make objects beautiful.

• They help us identify and describe things.

• They are used in art, painting, and decoration.

• They are used in traffic lights and road signs.

• They help us distinguish one object from another.

LESSON 2 – MEANING OF A RAINBOW

A rainbow is a band of seven colours that appears in the sky when sunlight shines through raindrops.

The colours of the rainbow are called the components of light because they are the different colours that make up white light from the Sun.

COMPONENTS (COLOURS) OF THE RAINBOW

The seven colours of the rainbow are:

1. Red

2. Orange

3. Yellow

4. Green

5. Blue

6. Indigo

7. Violet

A simple way to remember them is: 

R – O – Y – G – B – I – V

(Red, Orange, Yellow, Green, Blue, Indigo, Violet)

IMPORTANCE OF THE RAINBOW

1. It shows that white light is made up of seven colours.

2. It is a natural and beautiful sight in the sky.

3. It helps us learn about light and colours.

4. It is used in the study of science.

LESSON 3 – MEANING OF COLOUR PRODUCTION

Colour production is the process of making new colours by mixing two or more colours together.

Artists and painters mix colours to produce different shades for drawing and painting.

MIXING PRIMARY COLOURS

The three primary colours are red, blue, and yellow.

When primary colours are mixed, they produce secondary colours.

• Red + Yellow = Orange

• Yellow + Blue = Green

• Blue + Red = Purple (Violet)

MIXING NEUTRAL COLOURS

• Black can be added to make a colour darker.

• White can be added to make a colour lighter.

USES OF COLOUR MIXING

1. It is used in painting and drawing.

2. It is used in printing.

3. It is used in decorating houses.

4. It is used in making clothes and fabrics.

5. It is used in making signs and artworks.

LESSON 4 – MEANING OF NATURAL SOURCES OF COLOUR

Natural sources of colour are colours that come from nature. They are not made by humans but are found naturally in plants, animals, and the environment.

Examples of Natural Sources of Colour

• Flowers – Different flowers have colours such as red, yellow, white, purple, and pink.

• Leaves – Most leaves are green because of chlorophyll.

• Fruits – Fruits such as oranges, bananas, tomatoes, and mangoes have natural colours.

• Vegetables – Carrots, peppers, spinach, and pumpkins have natural colours.

• Rainbow – The rainbow shows the seven natural colours of light.

• The Sky – The sky appears blue during the day.

• Animals – Birds, butterflies, fish, and some insects have beautiful natural colours.

IMPORTANCE OF NATURAL COLOURS

1. They make the environment beautiful.

2. They help us identify plants and animals.

3. They attract insects for pollination.

4. They are used to make natural dyes.

5. They help us appreciate nature.

SUMMARY

In this lesson, pupils learned that colours are the different appearances of light that we see with our eyes. They identified the three types of colours: primary colours (red, blue, and yellow), secondary colours (orange, green, and purple), and neutral colours (black, white, and grey).

They also learned that a rainbow is formed when sunlight passes through raindrops and that it contains seven colours: Red, Orange, Yellow, Green, Blue, Indigo, and Violet (ROYGBIV).

Furthermore, pupils learned that new colours can be produced by mixing primary colours. For example, red and yellow produce orange, yellow and blue produce green, and blue and red produce purple (violet).

Finally, pupils learned that natural sources of colour include flowers, leaves, fruits, vegetables, the rainbow, the sky, and animals. Colours make our environment beautiful and help us identify and describe different objects.
