Rainbows form when sunlight passes through raindrops in the sky. The light bends and splits into different colours, creating a beautiful arc. Rainbows usually appear after rain, bringing joy and wonder to everyone who sees them. Enhance your paragraph-writing skills on the “How Rainbows Form” in four styles—Expository, Persuasive, Descriptive, and Narrative—while structuring your ideas effectively with PEEL, TEEL, TEXAS, and the Hamburger Model.

Different Styles of Paragraphs on ‘How Rainbows Form’

1. Expository Paragraph on How Rainbows Form (Explains with Facts)

A rainbow is a beautiful natural phenomenon that occurs when sunlight interacts with water droplets in the atmosphere. When sunlight enters a raindrop, it bends because light travels more slowly in water than in air. This bending of light is called refraction. After entering the droplet, the light reflects off the inside surface and then refracts again as it exits. During this process, the white sunlight separates into seven distinct colours—red, orange, yellow, green, blue, indigo, and violet—because each colour bends at a slightly different angle. This separation is known as dispersion. The result is a colourful arc that appears opposite the sun. Rainbows usually occur after rainfall when the air is still moist, or near waterfalls and fountains where tiny water droplets float in the air. They are always curved because the light is dispersed in a circle, though from the ground we only see part of it. Thus, a rainbow is not just a magical sight but also a clear example of how light behaves when it meets water droplets.

2. Persuasive Paragraph on How Rainbows Form (Tries to Convince You)

Understanding how rainbows form is not only interesting but also important for appreciating the science behind everyday wonders. Many people admire rainbows without realizing the fascinating process happening in the sky. By learning about refraction, reflection, and dispersion, students can develop a deeper curiosity about the natural world. Knowing that sunlight splits into colours when it passes through water droplets helps children connect classroom science with real-life experiences. This knowledge can inspire them to observe nature more closely and ask meaningful questions. Teaching this simple concept encourages scientific thinking and problem-solving skills, which are essential for future learning. Moreover, understanding rainbows helps us see that nature operates through patterns and laws, not magic or mystery. When children learn the true process behind a rainbow, they begin to appreciate the beauty of physics in action. Therefore, educators and parents should make an effort to explain how rainbows form so that children can grow into thoughtful, knowledgeable, and curious individuals who value science in their daily lives.

3. Descriptive Paragraph on How Rainbows Form (Paints a Picture with Words)

After a gentle rain, the sky often transforms into a canvas of soft light and drifting clouds. Suddenly, a rainbow appears, stretching gracefully across the horizon like a giant, colourful ribbon. Its colours blend smoothly from warm red to cool violet, each shade glowing softly against the fading grey of the clouds. The air feels fresh and still, carrying the scent of rain as sunlight breaks through. The rainbow looks almost magical, as if someone painted it carefully with transparent brushes. Tiny droplets in the air capture the sunlight, scattering the colours and giving the arc its delicate brightness. Birds fly beneath it, their wings shining faintly as they glide through the moist air. Children stop to stare, pointing excitedly as the arch becomes stronger and clearer. In that moment, the world seems calm, peaceful, and full of wonder. A rainbow does not last long, but while it is visible, it fills the sky with beauty that feels both mysterious and comforting, reminding us of the quiet charm hidden in nature.

4. Narrative Paragraph on How Rainbows Form (Tells a Story)

One afternoon, after a sudden shower, I stepped outside to feel the cool breeze. The ground was still wet, and the scent of rain lingered in the air. As the clouds slowly drifted apart, a bright ray of sunshine broke through. I looked up and gasped—a rainbow had formed across the sky. It arched beautifully, its colours vivid and perfectly arranged. I ran to call my little sister, who came rushing out with wide, excited eyes. Together, we stood in the open, watching the colours sparkle softly in the sunlight. She asked how the rainbow appeared, and I explained that sunlight bends and separates when it passes through tiny water droplets in the air. She listened carefully, amazed that something so magical came from something as simple as light and water. For a while, we just stood there, enjoying the calm after the rain. Slowly, the rainbow began to fade, but the moment stayed with us. It felt like nature had gifted us a quiet, colourful memory that we would always treasure.

‘How Rainbows Form’ Paragraphs in Different Structured Methods

1. How Rainbows Form Paragraph Writing with the PEEL Method

PEEL Method (Point, Evidence, Explanation, Link)

Point: Rainbows form when sunlight and rain come together, especially.

Evidence: When sunlight enters a raindrop, it bends and splits into many colours.

Explanation: The raindrop works like a tiny prism. It breaks the light into seven beautiful colours—red, orange, yellow, green, blue, indigo, and violet. When millions of raindrops do this at the same time, we see a rainbow in the sky. Rainbows usually appear when the sun comes out right after rain.

Link: That is why rainbows are colourful and magical—they are made by sunlight and raindrops working together.

2. How Rainbows Form Paragraph Writing with the TEEL Method

TEEL Method (Topic, Evidence, Explanation, Link)

Topic: Rainbows form when sunlight shines through raindrops.

Evidence: For example, when it rains lightly and the sun appears, the raindrops act like prisms and make a colourful arc in the sky.

Explanation: The light bends and separates into different colours inside each raindrop.

Link: This is why rainbows appear after rain and look so bright and beautiful.

3. How Rainbows Form Paragraph Writing with the TEXAS Method

TEXAS Method (Topic, Example, Explanation, Analysis, Summary/Significance)

Topic: Rainbows are formed by sunlight bending inside raindrops.

Example: One day after a drizzle, I saw a huge rainbow stretching across the sky because the sun peeked out at the perfect time.

Explanation: When light enters a raindrop, it changes direction and splits into many colours.

Analysis: This shows that rainbows appear when sunlight and raindrops meet at the right angle.

Summary: So, rainbows form through light bending in raindrops and creating beautiful colours

4. How Rainbows Form Paragraph Writing with the Hamburger Method

Hamburger Method (Top Bun, The Fillings, Bottom Bun)

Top Bun (Topic Sentence):
Rainbows form in the sky when sunlight meets raindrops.

The Fillings (Supporting Details):
Each raindrop bends the sunlight and splits it into seven colours. These colours spread out and form a beautiful arc. Rainbows usually appear when the rain is ending, and the sun comes out again. The sky becomes bright, and the colours shine clearly.

Bottom Bun (Concluding Sentence):
That is why we often see colourful rainbows after rain—they are made by sunlight shining through tiny raindrops.
