Why Do Leaves Change Color in Fall? 🍂

0:00Why Do Leaves Change Color in Fall?

LumiHave you ever wondered why green leaves turn yellow, orange, and red in fall?

BrikWatch closely, right here under the stars, and our whole falling-leaf answer begins.

BrikBrik points to a quiet forest, every leaf still deep green in the dark.

LumiNot one single leaf out there looks orange or red yet, only quiet green.

BrikGod the Father shaped the hills, the water and every little animal because He loves us, and He tells us: call Me Father.

LumiGood morning, dear friends! We are Brik and Lumi, and today we got up very early to watch the sunrise together.

BrikLook, the stars are still shining, and in a few minutes the sun will come up just for us.

LumiOpen your eyes wide and come along, today something special is waiting.

BrikCan you say autumn? Autumn. The cool season when leaves change color and fall.

LumiEvery green leaf out there is quietly hiding a whole secret color inside.

BrikGod the Father loves every one of us, and He wants each of you to be with Him in Heaven one day.

LumiBy morning, we will watch that secret color slowly begin to show through.

BrikEven in the dark, the whole forest smells cool, crisp, and a little sweet.

LumiA fox! Can you say fox? Fox.

2:00What Happens in the Green Forest at Night?

BrikThe whole forest rests quiet, close together, safe under the wide night sky.

LumiCurled up like this, Coco's red coat matches leaves that have not turned yet.

BrikNot one single leaf in the whole forest stops its soft, gentle rustle tonight.

BrikThe Lord Jesus was sent to us so that we could be truly happy.

LumiResting quietly like this, Coco feels warm and safe beside her two best friends.

BrikThe whole forest waits patiently.

LumiCan you wait quietly too?

BrikNot one star stops twinkling.

LumiCoco leans into Brik's side, warm and safe beneath the quiet trees.

BrikThe stars above the forest blink, calm and perfectly still tonight.

LumiA little cricket! Can you say cricket? A tiny bug that sings at night.

BrikIts small song rises and falls, soft and steady over the sleeping forest.

LumiMary holds our hand like the very best Mother, because she is our Mother and the Queen of Heaven.

BrikCan you say chlorophyll? Chlorophyll. The green color that helps a leaf catch sunlight.

LumiEvery leaf out there uses chlorophyll all summer to help the whole tree grow.

BrikLet's build somewhere warm, right where we can rest before our long day begins.

BrikLook what we are building today, come closer and watch with us!

LumiA cozy wooden cabin, hung with soft lanterns from one wall to the other.

4:20Why Is Giggles Scared of the Night Storm?

BrikWe are calling it The Lantern-Lit Forest Cabin.

LumiInside, soft blankets wait folded, ready for a long, cool autumn night.

LumiBlock by block, slowly, and it is already growing taller.

BrikBeam by beam, and lantern by lantern, rising warm against the dark.

LumiCoco ambles up to the new cabin, sniffing the fresh, warm wood.

BrikIt is finished! Look how beautiful it turned out.

LumiThe Lantern-Lit Forest Cabin is finished, glowing soft under the wide night sky.

BrikFrom here, every leaf outside will stay quiet, dark, and green a little longer.

LumiAnd now a riddle, listen carefully.

LumiBrik counted every green leaf still hanging on one quiet tree tonight.

BrikHow many green leaves are hanging on that tree tonight?

BrikTake your time, it is good to think a little longer.

LumiWell done, exactly right! I heard how beautifully you answered.

LumiFour green leaves, hanging quietly. One, two, three, four.

BrikFour little leaves, and every single one hides a secret color inside.

BrikTime to get to work, and work is much nicer when we do it together.

BrikOne small lantern, glowing softly right beside the new forest cabin.

LumiWe are calling it The First Cabin Lantern.

BrikIts warm little glow lights up the nearest branch just enough to see.

LumiWe did it, and we did it together.

LumiThe First Cabin Lantern is ready, and three more will soon glow beside it.

BrikLook, out past the trees, a thick black cloud rolls in fast.

LumiThe whole sky darkens in a few quick seconds, and the wind picks up.

BrikA bright zigzag flashes across the whole dark sky, quick and silver-white.

LumiFor one whole second, the entire forest glows bright as daylight.

BrikDo not worry, Giggles, that flash is only bright light, quick and harmless.

LumiWe are right here together, safe and warm, and it is already rolling past.

BrikGiggles peeks out slowly, and the little hedgehog uncurls beside him, calm again.

LumiSomewhere in the wet grass, a frog croaks happily at every warm raindrop.

BrikCan you say thunder? Thunder. The deep, rolling sound after a flash of light.

LumiLight travels so fast, we see the flash long before the thunder ever arrives.

BrikThe rain patters gentle on every leaf, and the thick cloud rolls on by.

LumiLook, the sky is clearing already, calm and dark and full of stars again.

BrikGiggles hops up, giggling with relief, glad the whole sky is quiet once more.

BrikTime for a question, think for a moment.

LumiBrik counted every bright star peeking back out after the clouds rolled by.

BrikHow many bright stars are peeking back out over the forest?

LumiHave a think, we will wait for you.

BrikBravo, that is it! You are real Dream Builders.

BrikFive bright stars, peeking back out. One, two, three, four, five.

LumiFive little stars, and every single one shines calm again over the quiet forest.

9:20Why Is the Sky Turning Gold Over the Forest?

LumiBring the blocks, dear builders, we are starting something new.

LumiOne tall, thin tower, built from smooth boards right beside the cabin.

BrikWe are calling it The Night-Watch Cabin Tower.

LumiClimb up, and the whole dark forest spreads out quiet beneath you.

BrikIt is finished! Look how beautiful it turned out.

BrikThe Night-Watch Cabin Tower stands tall, and Lumi waves gently from the top.

BrikWhat a curious, patient start to our very long day.

LumiIf you like what we built, show us a thumbs up!

BrikCan you say curious? Curious.

LumiLook what we are building today, come closer and watch with us!

BrikOne small bridge, leading toward the edge where the sun will soon rise.

LumiWe are calling it The Dawn-Forest Bridge.

BrikIts planks glow pale gold already, leading straight toward the morning light.

BrikWe did it, and we did it together.

LumiThe Dawn-Forest Bridge is ready, and Coco is already standing at the far end.

BrikLook, past the tower, the deep dark sky is starting to change.

LumiIt is turning from deep black to a soft, gentle shade of grey.

BrikThe stars are fading, one by one, like little candles going out slowly.

LumiWatch closely, the edge of the sky is starting to glow soft and warm.

BrikA thin golden line grows wider, along the far edge of the forest.

11:40What Is the Great Color-Changing Forest Tree?

LumiOne by one, the sleepy branches begin to stir, ready for a new day.

BrikLook, the sun is climbing higher and the whole world is turning golden.

LumiThe whole forest is waking up in gold, right before our eyes.

BrikGood morning, sleepy forest! The sun is finally, wonderfully, all the way up.

LumiThe last cool shadow fades, and the whole forest glows bright golden warm.

BrikCan you say golden? Golden.

LumiNow, in the light of this brand new day, let's solve our whole color mystery.

BrikWhy does a green leaf slowly turn yellow, orange, and finally bright red?

LumiLet's look closely at one leaf, right here in the cool morning light.

BrikBrik gently holds one leaf up in the soft autumn sunshine.

LumiIts green color is already fading a little, right at the very edges.

BrikA rabbit! Can you say rabbit? Rabbit.

LumiHer name is George, and she hops closer, curious about the fading green.

BrikGeorge twitches her ears at every leaf that drifts gently down past her.

LumiTime to get to work, and work is much nicer when we do it together.

LumiOne round flower bed, opening its petals in the very first warm light.

BrikWe are calling it The Morning Gold-Leaf Flower Bed.

LumiIts petals open in rings of gold and orange, just like the turning leaves.

BrikIt is finished! Look how beautiful it turned out.

BrikThe Morning Gold-Leaf Flower Bed is ready, glowing warm in the early light.

LumiCan you say fade? Fade. To slowly become softer, paler, or less bright.

BrikAs the days grow shorter and cooler, a leaf's green chlorophyll starts to fade.

LumiCan you say vein? Vein. One of the thin lines that carry water through a leaf.

BrikThe morning grass is still a little damp, cool and soft beneath their feet.

LumiSomewhere close by, a bee hums low and busy among the gold-leaf flower bed.

BrikNot one single leaf on the whole tree turns color at quite the same moment.

LumiBubu's ears twitch twice, then she settles down to watch the tree glow gold.

BrikThe whole forest smells warm and dusty, like sun-warmed leaves and fresh moss.

LumiBrik taps the tree gently, and one more leaf glows a little brighter.

BrikGeorge hops closer, sniffing curiously at the very lowest golden branch.

LumiHere comes a riddle, say the answer out loud!

BrikBrik counted every glowing color band on the great color-changing tree.

LumiHow many colors are glowing on the great tree so far?

15:50Why Do Some Leaves Turn Red?

BrikTake your time, it is good to think a little longer.

LumiWonderful, you got it! I am so proud of you.

LumiSix glowing colors, counted carefully. One, two, three, four, five, six.

BrikSix warm colors, from deep green all the way to the very brightest red.

BrikLet's build somewhere big, right where the whole forest can see our giant answer.

BrikBring the blocks, dear builders, we are starting something new.

LumiA giant, blocky tree, banded green, yellow, orange, and bright ripe red.

BrikWe are calling it The Great Color-Changing Forest Tree.

LumiAs the green band fades, the yellow hiding underneath shows through at last.

LumiSee how nicely it fits, one block sitting neatly on another.

BrikBlock by block, and band by band, rising taller with the morning sun.

LumiCan you say pigment? Pigment. A tiny bit of color hidden inside every leaf.

BrikCoco trots right underneath the great tree, watching its colors glow warm.

LumiYellow and orange pigments were hiding there all along, just like our sky.

BrikWe did it, and we did it together.

LumiThe Great Color-Changing Forest Tree is finished, and Coco settles down to watch.

BrikCan you say anthocyanin? Anthocyanin. A brand new red color some leaves paint themselves.

LumiSome leaves use their own leftover sugar to paint a whole brand new red.

BrikThat is the whole secret: green fades away, hidden colors show, and some turn red.

LumiNot one single leaf on that whole tree ever skips its own colorful turn.

BrikBrik claps his hands, delighted at how one green leaf hides a whole rainbow.

LumiAnd now a riddle, listen carefully.

LumiBrik counted every bright yellow leaf hanging on one single branch.

BrikHow many yellow leaves are on that one branch?

BrikHave a think, we will wait for you.

LumiWell done, exactly right! I heard how beautifully you answered.

BrikFive yellow leaves, counted brightly. One, two, three, four, five.

LumiFive golden leaves, and every single one was hiding that color since spring.

BrikLook what we are building today, come closer and watch with us!

BrikFour little steps, each one painted a different autumn leaf color.

LumiWe are calling it The Four Leaf-Color-Counting Steps.

BrikStep up slowly, counting each color, all the way to the top step.

LumiWe are not in a hurry, because things made carefully last the longest.

LumiOne green step, two yellow, three orange, then four, bright red at the top.

BrikIt is finished! Look how beautiful it turned out.

BrikThe Four Leaf-Color-Counting Steps are finished, and George hops up every one.

LumiA deer! Can you say deer? Deer.

BrikHer name is Bubu, and she noses closer, curious about the color-changing tree.

LumiBubu's own coat stays the very same color all through the whole autumn.

LumiOh, Giggles, rubbing berries on a leaf is not the same as true color change.

BrikHe grins, wipes off the sticky mess, and happily waits for autumn's own work.

LumiThe forest settles back into its warm, sunny calm.

LumiTime to get to work, and work is much nicer when we do it together.

LumiOne small feeder, filled with autumn seeds, right beside the color tree.

BrikWe are calling it The Morning Forest Feeder.

LumiPeck, peck, peck — every little bird loves autumn seeds in the morning sun.

BrikWe did it, and we did it together.

BrikThe Morning Forest Feeder is ready, and small birds gather round it happily.

LumiCan you say shorter? Shorter. Not lasting as long as it did before.

BrikShorter, cooler autumn days are the very reason every leaf begins to change.

LumiTime for a question, think for a moment.

LumiBrik counted every rabbit and deer gathered near the color-changing tree.

BrikHow many friends are gathered near the tree?

BrikTake your time, it is good to think a little longer.

LumiBravo, that is it! You are real Dream Builders.

BrikFive happy friends, gathered calmly. One, two, three, four, five.

LumiFive little friends, and every single one enjoys the very same warm morning sun.

BrikThe sun is climbing high above the forest now, warm on every turning leaf.

LumiThe sun is high above us, it is exactly noon, time for a little rest.

BrikLet us sit down for a moment and listen to how beautifully quiet it is around us.

LumiLet's rest a moment here in the warm midday sun, listening to the forest hum softly.

BrikLet's follow the warm midday sun, over to where the fallen leaves are piling up.

23:20What Is the Crunchy Leaf-Pile Playground?

LumiPast the tree, the ground opens into a small, sunny forest clearing.

BrikLeave a thumbs up if you are enjoying building with us, it helps other children find us.

LumiLook, a soft breeze carries whole handfuls of colorful leaves through the air.

BrikThis is the very best time to see exactly why a leaf finally lets go.

LumiCan you say seal? Seal. A tiny, snug layer that closes something up safely.

BrikA dog! Can you say dog? Dog.

LumiHer name is Tom, and she bounds closer, chasing every leaf that drifts by.

BrikTom pounces at leaf after leaf, never quite catching a single spinning one.

LumiLet's build somewhere fun, right where the whole forest can play in fallen leaves.

BrikBring the blocks, dear builders, we are starting something new.

BrikA wide, cheerful playground, piled high with every color of fallen leaf.

LumiWe are calling it The Crunchy Leaf-Pile Playground.

BrikEach leaf grew its own tiny seal at the base of its stem before letting go.

LumiA little more and it will be ready, do you like it so far?

LumiBlock by block, and leaf by leaf, rising bright with the midday sun.

BrikCan you say release? Release. To gently let go of something on purpose.

LumiGeorge leaps right into the great leaf pile, tumbling in a happy, crunchy heap.

BrikThat tiny seal protects the whole tree through winter after each leaf lets go.

BrikIt is finished! Look how beautiful it turned out.

LumiThe Crunchy Leaf-Pile Playground is finished, warm and golden in the sun.

BrikCan you say protect? Protect. To keep something safe from cold or harm.

LumiLetting go of its leaves helps a whole tree protect itself through winter's cold.

LumiOh, Giggles, that leaf pile is much deeper and stickier than it looked.

BrikHe shakes off every last leaf, giggling at his own funny, leafy costume.

LumiThe clearing settles back into its warm, sunny calm.

LumiHere comes a riddle, say the answer out loud!

BrikBrik counted every colorful leaf piled up in one great crunchy heap.

LumiHow many leaves are piled up in that one crunchy heap?

BrikHave a think, we will wait for you.

LumiWonderful, you got it! I am so proud of you.

LumiEight colorful leaves, counted carefully. One, two, three, four, five, six, seven, eight.

BrikEight bright leaves, and every single one grew its own protective little seal.

BrikLook what we are building today, come closer and watch with us!

LumiOne small signpost, pointing one way to the tree, one to the playground.

BrikWe are calling it The Tree-Or-Playground Signpost.

LumiOne arrow points back to the colors, the other to the crunchy leaves.

LumiWe did it, and we did it together.

BrikThe Tree-Or-Playground Signpost is ready, and Lumi reads it out loud, delighted.

BrikTime to get to work, and work is much nicer when we do it together.

BrikOne spinning pinwheel, right beside the playground, catching every autumn breeze.

LumiWe are calling it The Forest Breeze Pinwheel.

BrikA cool breeze sends whole handfuls of leaves spinning across the clearing.

LumiIt is finished! Look how beautiful it turned out.

LumiThe Forest Breeze Pinwheel spins gently, and Tom watches it turn round.

BrikLook, a soft grey cloud is drifting closer, carried on the very same wind.

LumiQuick, let's build one small shed, right where a few dry leaves stay safe.

BrikBring the blocks, dear builders, we are starting something new.

LumiOne tiny shed, just big enough for a few extra piles of dry leaves.

BrikWe are calling it The Little Leaf-Pile Shed.

LumiIts little window lets us peek in at every neat little pile inside.

29:40Why Do Windy Showers Make Leaves Fall?

LumiWe did it, and we did it together.

BrikThe Little Leaf-Pile Shed is ready, tucked snug beside the playground.

BrikListen, a short, windy little shower patters softly over the whole clearing.

LumiLook how the wind and rain together shake loose leaf after loose leaf.

BrikOne by one, whole handfuls of color spiral gently down to the ground.

LumiThe short shower passes quickly, and the wind carries the leaves on ahead.

BrikThe sun is starting to lean low now, painting the whole clearing gold.

LumiLook, way out past the playground, another dark cloud is rolling closer.

BrikThe whole sky darkens fast, and a bright zigzag flashes on the far horizon.

LumiLet's count together: light travels faster than sound, so we hear thunder after.

BrikAnd now a riddle, listen carefully.

BrikCount with Brik: one, two, three, four, and then comes the low, rolling boom.

LumiHow many seconds passed between the flash and the thunder?

LumiTake your time, it is good to think a little longer.

BrikWell done, exactly right! I heard how beautifully you answered.

BrikFour whole seconds, counted steady. One, two, three, four.

LumiFour seconds means that far-off storm is still safely, quietly distant.

BrikNot one single leaf on the whole tree minds a little more autumn rain.

LumiEvery leaf still hanging on stays perfectly calm through the gentle storm.

LumiTime for a question, think for a moment.

LumiBrik counted every deer and fox visible across the whole forest clearing.

BrikHow many deer and foxes are visible in the forest?

BrikHave a think, we will wait for you.

LumiBravo, that is it! You are real Dream Builders.

BrikFour calm friends, resting steady. One, two, three, four.

LumiFour forest friends, and every single one feels warm and safe through the rain.

BrikListen, the far-off rumble is fading, softer and slower, one by one.

LumiLook, the sky is clearing fast, bright and freshly washed above the forest.

BrikLook up — a whole bright rainbow is arching over the tree, all on its own!

LumiEvery dog, rabbit, and deer nearby settles calm again in the warm sun.

BrikCan you say drift? Drift. To move slowly and gently, carried along by the wind.

LumiA single dragonfly skims low across the clearing, quick and shimmering blue-green.

BrikThe warm leafy smell drifts all the way to the edge of the whole forest.

LumiNot one single leaf in the pile landed in quite the same spot as another.

BrikSomewhere close by, the playground's leaves rustle once, steady and slow.

LumiTom's fur stays warm, even resting close beside the crunchy leaf pile.

BrikThe clearing feels warm, golden, and wonderfully busy with today's whole harvest.

LumiNot one single cloud today ever looked quite the same shape as another.

LumiLet's follow the low, golden sun back toward the tree and the whole forest.

LumiBack near the tree, the whole sky is turning a deep, glowing orange and pink.

BrikLook, the sunset sky glows the same warm orange as our brightest autumn leaf.

LumiCan you say sunset? Sunset. That is when the sun goes down low in the sky.

BrikCan you say dusk? Dusk. That is the soft, quiet time just before full dark.

BrikAs the great sun sinks low, more leaves let go and drift gently down.

LumiLet's watch the sky turn deeper.

BrikIts glow fades slow and gentle.

BrikLook what we are building today, come closer and watch with us!

LumiOne small pyramid, stacked from tiny blocks in every autumn leaf color.

BrikWe are calling it The Leaf-Color Pyramid.

BrikEvery little block glows its own warm hue, stacked five rows high.

LumiIt is finished! Look how beautiful it turned out.

LumiThe Leaf-Color Pyramid is ready, and it glows soft in the fading light.

LumiOh, Giggles, a falling leaf is trickier to catch than it looks, is it not?

BrikHe grins cross-eyed at the leaf on his nose, and everyone laughs warmly.

LumiThe forest settles back into its warm, glowing calm.

BrikGive us a thumbs up if you want to see the next episode!

LumiCan you say cozy? Cozy. It means warm, soft, and safe, exactly like tonight.

BrikTime to get to work, and work is much nicer when we do it together.

BrikOne small wooden bench, facing straight toward the whole glowing tree.

LumiWe are calling it The Cabin-Watching Bench.

BrikSit here quietly, and watch every leaf glow softly against the dark sky.

LumiWe did it, and we did it together.

LumiThe Cabin-Watching Bench is ready, and Lumi is already curled up, watching.

BrikBrik pats the little bench gently, proud of the whole long, colorful day.

LumiCan you say proud? Proud. We built and learned so much today.

BrikCan you say celebrate? Celebrate. To share a happy moment together with friends.

LumiBubu settles onto a low patch of grass, warm beside the glowing fire.

BrikGeorge naps curled up beside the pyramid, warm in its colorful glow.

LumiEvery fallen leaf tonight remembers the very same branch that once held it.

38:20How Does the Whole Forest Rest Together at Night?

BrikThe whole sky above the forest fills slowly with hundreds of tiny stars.

LumiCan you say gentle? Gentle. Soft and careful, never rough at all.

BrikBrik counts the lanterns one more time, just for the simple joy of it.

LumiLumi hums a happy little tune, watching the whole forest glow together.

BrikNot one single branch tonight sits bare; every tree still holds a few last leaves.

BrikHere comes a riddle, say the answer out loud!

BrikThree leaves drifted down before supper, then four more drifted down after.

LumiHow many leaves drifted down altogether today?

LumiTake your time, it is good to think a little longer.

BrikWonderful, you got it! I am so proud of you.

BrikThree and four makes seven. One, two, three, four, five, six, seven.

LumiCan you say altogether? Altogether.

BrikSeven colorful leaves, and every single one hid a whole rainbow inside it.

LumiLet's build one last place, right where the whole forest can rest together.

LumiBring the blocks, dear builders, we are starting something new.

BrikA wide, welcoming camp, ringed with lanterns from one side to the other.

LumiWe are calling it The Cozy Autumn Campfire.

BrikOne by one, its lanterns glow, each one warmer than the last.

BrikBlock by block, slowly, and it is already growing taller.

LumiPost by post, and lantern by lantern, filling up with today's last golden light.

BrikThe campfire glows the same warm orange as the whole sunset sky above it.

LumiCoco curls up close to the fire, her red coat glowing warm beside the flames.

BrikEvery friend gathers close, watching the whole colorful forest glow together.

LumiIt is finished! Look how beautiful it turned out.

LumiThe Cozy Autumn Campfire is finished, glowing warm under the very first stars.

BrikLook, it is dark again now, just like it was at the start of our day.

LumiBut this time, we know exactly why leaves change color every single fall.

BrikGreen fades away, hidden colors show through, and some leaves paint themselves red.

LumiListen to the forest grow quiet.

BrikCan you say cozy? Cozy.

LumiCozy just means warm, soft, and safe, exactly like our whole forest tonight.

BrikNot one single leaf tonight ever changed color without its own patient time.

LumiA single lantern still glows in the same cabin window, steady every night.

BrikSomewhere close by, a cricket starts up its same, steady song once more.

LumiTom's ears twitch softly in the very last warm light before dark settles.

BrikThe whole forest smells of fallen leaves and cool, settling autumn air.

42:40Why Do Leaves Really Change Color? The Whole Answer

LumiNot one lantern around the whole camp glows in quite the same gold.

BrikA single star returns to the same corner of the sky, night after night.

LumiGeorge naps curled up beside the pyramid, warm in its colorful glow.

BrikThe night feels calm, complete, and wonderfully, warmly still.

BrikIf you want to build with us tomorrow, ask your mum or dad to press Subscribe.

LumiPress Subscribe together with your parents, and Brik and Lumi will be here waiting for you tomorrow.

BrikIf you had a good time with us, press Subscribe so you do not lose our cartoon.

LumiThe stars are twinkling again, and our long, beautiful day is slowly coming to an end.

BrikWe built so much today, and we learned even more.

LumiThank you for being with us, it was much nicer together.

BrikSo remember, green fades away, hidden colors show through, and some leaves turn a brand new red.

LumiThe tree glows soft and warm one last time, calm under the bright stars.

LumiGiggles waves from far away before he disappears for the night, and the little bells on his cap ring softly.

BrikBye bye! Sleep sweetly, our dear friends.
