A Farm Rainbow

A Rainbow Story Through Time

Not long ago, a kid about your age stood outside just after the rain. The ground was still wet, the air smelled fresh, and the sun started peeking through the clouds. They looked up—and there it was. A rainbow stretched across the sky. They ran to find it. Across the yard. Past the garden. Around the trees. But no matter how far they went, the rainbow stayed just out of reach. They stopped and wondered… What is it? And where does it go? People have been asking those same questions for thousands of years.

Long before we understood the science, people created stories to explain what they were seeing:

In Ireland, people told stories about leprechauns hiding gold at the end of rainbows.

In ancient Greece, the rainbow was thought to be a path used by a messenger traveling between worlds.

In some cultures, rainbows were seen as bridges, signals, or signs that something was changing.

Sailors once believed rainbows could even help predict the weather.

For a long time, no one knew the real answer.

Splitting Sunlight

Then, a scientist named Isaac Newton decided to look more closely at light. Instead of just watching rainbows, he wanted to figure out how they worked.

Around 1666—over 350 years ago—he did a simple experiment. He let sunlight shine through a piece of glass called a prism. When the light passed through, something amazing happened.

The white light spread out into many different colors.

That’s when he realized something important: sunlight isn’t just one color—it’s made up of many colors mixed together. When light moves through water or glass, it slows down and bends. Each color bends just a little bit differently, which causes them to spread apart into a rainbow.

So a rainbow isn’t something being added to the sky—it’s something that was already hidden inside the light, just waiting to be seen.

Try This: Split the Light

You don’t need a laboratory to see what Newton discovered.

Option 1: Water Glass Rainbow

• Fill a clear glass with water

• Place it in direct sunlight near a wall or floor

• Slowly move it until you see a rainbow reflection appear

Option 2: Garden Rainbow

• Turn on a hose or sprinkler

• Stand with the sun behind you

• Adjust your position until the colors appear in the mist

Option 3: Bubble Rainbow

• Blow bubbles in the sunlight

• Watch closely as colors swirl across the surface

Ask:

• Where do you see the colors first?

• What happens when you move?

• Can you find the “right angle” again?

It’s the same discovery—just in your backyard.

Did You Know?

• Rainbows are actually circles, not just arches. We usually only see part of them because the ground blocks the rest—but if you’re high enough (like in an airplane), you can see the whole circle.

• The shape and position of a rainbow changes depending on where the sun is in the sky. Lower sun = taller rainbow. Higher sun = shorter rainbow.

• You will always see a rainbow with the sun behind you.

• Sometimes you can see a double rainbow—the second one is fainter and has its colors in reverse order.
  This happens because the light bounces twice inside the raindrop instead of once, flipping the colors.

• Inside each raindrop, light bends as it enters, then hits the back and bounces like it’s hitting a tiny curved mirror before coming back out.

• Large raindrops, like the ones in a big storm, create the most vivid and bright rainbows because they separate the colors more clearly.

• If the moon is bright enough, you can sometimes see a rainbow at night—called a moonbow.

• No two people see the exact same rainbow—it depends on where you are standing.

🌈 Color on the Farm

A rainbow isn’t just something you see after the rain.

It’s light bending through water.
It’s color growing in the soil.
It’s signals in plants, patterns in animals, and food on our table.

From chasing a rainbow across the yard…
to discovering how sunlight splits into color…
to finding those same colors growing all around us—
we start to see the world a little differently.

If you start looking closely, you’ll find those same colors all around the farm—growing in the soil, shining in the orchard, and woven into the animals we care for.

On the farm, color is everywhere. And that color isn’t just for beauty—it has a purpose.

In plants, color helps them do their jobs. Green leaves capture sunlight to make energy. Bright flowers attract bees and pollinators. Reds, yellows, and oranges often signal ripeness, letting animals (and us) know when food is ready to eat.

In animals, color can help them survive. Some blend in to stay safe, while others stand out to attract attention or communicate.

The same sunlight that makes a rainbow in the sky
is the sunlight feeding the garden, the orchard, and everything we grow.

And once you start noticing that,
you can’t really stop seeing it. 🌈🌾

🍓 Can You build a rainbow on your plate?

Eat the Rainbow

Red: strawberries, raspberries, tomatoes, watermelon
Orange: carrots, oranges, sweet potatoes, pumpkin
Yellow: eggs, squash, corn, yellow peppers, pineapple
Green: spinach, cucumbers, peas, zucchini, herbs
Blue/Purple: blueberries, blackberries, purple cabbage, eggplant, plums

• Start simple—maybe just 3 colors.
  Then next time, try for all of them.

  You might notice:

  • Some colors are sweet

  • Some are crunchy

  • Some are brand new

  Every color brings something different to your body.

  And just like on the farm, the more color you grow and eat…
  the more life and variety you bring to your table. 🌿🌈

🌸 Our Farm Project: A Flower Rainbow

Our farm school project was to recreate a rainbow using flowers we found right here on the farm.

We started with a cardboard heart, (here is a LINK to my stencil) coloring it in the colors of the rainbow to use as a guide. Then we added a layer of contact paper to one side (sticky side facing out) so the flowers would easily stick as we worked.

From there, we set out across the farm, slowing down to really notice what we were finding. Each flower was a little different—some soft, some sturdy, some fragrant, some almost scentless. The shapes, textures, and colors all told their own story.

The goal wasn’t to fill every space, but to place petals thoughtfully, building a rainbow one piece at a time. Less is more in this case.

The trick is to cover enough to see the color… but leave space in between so the light can shine through like a suncatcher.

Once we finished, we sealed it by adding another piece of heart shaped contact paper on top, sandwiching the flowers inside.

Punch a small hole at the top, tie on a piece of twine, and help your kiddo hang it in a window where the light can shine through and you can admire it together.

Try to capture your rainbow

Whether it’s in the sky, your garden, or your kitchen.

Maybe it’s a quick moment after a storm, a sprinkler catching the sunlight, a basket of colorful vegetables, or a plate you built together. It doesn’t have to be perfect. Sometimes the best rainbows are the ones you almost miss.

Look for it in unexpected places—light through a glass of water, bubbles drifting in the sun, petals scattered across a table.

Slow down. Notice it. Capture it.

And if you can, take a photo—not just to share, but to remember the moment you stopped and really saw it.

Because here’s the part that still feels a little magical:

You can’t ever reach the end of a rainbow.
It isn’t a place—it’s something you see, depending on where you stand.

That means the rainbow you see… is yours. 🌈

And just like that kid in the yard,
we can still stop, look up, and wonder. 🌿

We’re not just teaching kids to see color—
we’re teaching them to notice the world.
