  This is the science edition of Do You Know Why Trivia?
• 0:37
  Get ready to test your science smarts with some cool questions
• 0:40
  and learn something amazing along the way.
• 0:43
  Grab your thinking cap, because it's time to find out just how
• 0:47
  much you know about the world of science.
• 0:49
  After each question, you'll get a few seconds to think before we
• 0:53
  reveal the answer. Let's get started.
• 0:56
  Here comes your very first do you know why question.
• 1:00
  Do you know why the sky looks blue during the day?
• 1:03
  Here's your clue. It has to do with sunlight and
• 1:06
  the air in our atmosphere. The answer is the sky looks blue
• 1:14
  because of something called scattering.
• 1:17
  Sunlight is made-up of many colors, but blue light scatters
• 1:21
  in all directions by the gases and particles in the atmosphere,
• 1:25
  making the sky appear blue to our eyes.
• 1:28
  Let's try another. This one is about animals.
• 1:32
  Do you know why Penguins don't fly even though they have wings?
• 1:35
  Here's your clue. Think about where Penguins spend
• 1:38
  most of their time. The answer is Penguins cannot
• 1:46
  fly because their wings are adapted for swimming, not
• 1:49
  flying. Their wings are shaped like
• 1:52
  flippers, perfect for moving quickly through water, which is
• 1:55
  where Penguins find their food. Now let's talk about plants.
• 2:00
  Do you know why plants are green?
• 2:02
  Clue. It's all about a substance
• 2:04
  inside their leaves. The answer is plants are green
• 2:13
  because of a pigment. Called chlorophyll.
• 2:15
  Chlorophyll helps. Plants capture sunlight to make
• 2:18
  their food, and it reflects green light, which is why leaves
• 2:22
  look green to us. Ready for a question about the
• 2:25
  human body? Do you know why your stomach
• 2:27
  growls when you're hungry? Here's your clue.
• 2:30
  It's not just because you need food.
• 2:36
  The answer is your stomach growls because of muscles in
• 2:40
  your stomach and intestines moving food and gas around.
• 2:44
  When your stomach is empty, these sounds are louder and
• 2:48
  easier to hear. Here's a fun one about space.
• 2:51
  Do you know why astronauts float in the International Space
• 2:54
  Station? Clue.
• 2:56
  It's not because there is 0 gravity.
• 3:03
  The answer is astronauts float because they are in a state of
• 3:07
  free fall orbiting Earth. They are falling toward Earth,
• 3:11
  but because the station is moving forward so fast, they
• 3:15
  keep missing it, creating a feeling of weightlessness.
• 3:18
  Next up, something to do with the weather.
• 3:21
  Do you know why it rains? Here's a clue.
• 3:24
  It involves water vapor in the air.
• 3:30
  The answer is it rains when water vapor in the air cools
• 3:34
  down and turns back into liquid water, forming clouds.
• 3:38
  When the clouds get too heavy, the waterfalls back to the
• 3:42
  ground as rain. Let's try a question about
• 3:45
  insects. Do you know why bees?
• 3:47
  Buzz Clue. It's not just to make noise.
• 3:55
  The answer is these buzz because their wings beat very quickly
• 3:59
  causing vibrations in the air. The sound you hear is the
• 4:03
  vibration or buzzing from their wings moving so fast.
• 4:08
  Time for question about volcanoes.
• 4:11
  Do you know why volcanoes erupt? Here's your clue.
• 4:14
  It starts deep underground. The answer is volcanoes erupt
• 4:23
  when molten rock called magma builds up pressure under the
• 4:27
  Earth's surface. When the pressure becomes too
• 4:30
  great, it pushes the magma out through openings, causing an
• 4:34
  eruption. Let's head back to the animal
• 4:37
  Kingdom for this one. Do you know why chameleons can
• 4:40
  change? Color clue.
• 4:42
  It's not just for hiding. The answer is chameleons change
• 4:50
  color to communicate with other chameleons and to control their
• 4:54
  body temperature. Their skin has special cells
• 4:58
  that can change how light is reflected, making different
• 5:01
  colors appear. Here's a brain teaser about
• 5:04
  sound. Do you know why your voice
• 5:06
  sounds different when you hear a recording of it?
• 5:09
  Here's your clue. It has to do with how you hear
• 5:11
  sounds. The answer is your voice sounds
• 5:19
  different on a recording because you usually hear your voice
• 5:22
  through vibrations inside your head and through the air.
• 5:26
  A recording only plays the sound through the air so it sounds
• 5:29
  higher or different than what you're used to.
• 5:32
  Now for question about the ocean.
• 5:35
  Do you know why the ocean is salty?
• 5:37
  Clue. Think about rain, rivers, and
• 5:40
  rocks. The answer is the ocean is salty
• 5:48
  because rain washes minerals from rocks on land into rivers,
• 5:52
  which flow into the sea. These minerals, especially salt,
• 5:56
  build up in the ocean over millions of years.
• 6:00
  Let's try a chemistry question. Do you know why baking soda and
• 6:04
  vinegar fizz when you mix them? Here's your clue.
• 6:07
  A gas is created. The answer is baking soda and
• 6:15
  vinegar fizz because they have a chemical reaction that makes
• 6:19
  carbon dioxide gas. The gas forms bubbles, causing
• 6:23
  the fizzing effect you see. Here's a fun one about ice.
• 6:27
  Do you know why ice floats in water?
• 6:29
  Clue. It's about how tightly the water
• 6:32
  molecules are packed. The answer is ice floats in
• 6:40
  water because it is less dense than liquid water.
• 6:43
  When water freezes, its molecules spread out and form a
• 6:47
  pattern that takes up more space, making ice lighter than
• 6:51
  the same amount of water. Let's talk about colors and
• 6:54
  rainbows. Do you know why we see rainbows
• 6:57
  after it rains? Here's your clue.
• 6:59
  Sunlight and raindrops work together.
• 7:06
  The answer is rainbows appear when sunlight passes through
• 7:10
  raindrops, which act like tiny prisms.
• 7:14
  They bend and split the light into different colors, creating
• 7:17
  a rainbow in the sky. Are you ready for another animal
• 7:21
  mystery? Do you know why owls can turn
• 7:24
  their heads so far around? Clue.
• 7:27
  It has to do with their neck bones.
• 7:33
  The answer is owls can turn their heads up to 270° because
• 7:38
  they have extra neck bones, 14 instead of the seven most
• 7:42
  mammals have. This helps them see in many
• 7:45
  directions without moving their bodies.
• 7:48
  Let's switch to something about energy.
• 7:50
  Do you know why rubbing your hands together makes them feel
• 7:53
  warm? Here's your clue.
• 7:55
  It's about movement and heat. The answer is rubbing your hands
• 8:04
  together creates friction, which turns the energy of movement
• 8:08
  into heat. That's why your hands feel
• 8:11
  warmer after you rub them. Here's a question about magnets.
• 8:15
  Do you know why magnets stick to some metals but not others?
• 8:18
  Clue. It's all about the kind of
• 8:21
  metal. The answer is magnets stick to
• 8:28
  metals that have iron, nickel, or cobalt in them.
• 8:32
  These metals have special properties that let them be
• 8:35
  attracted to magnets. Let's talk about the moon.
• 8:38
  Do you know why the moon looks different shapes during the?
• 8:41
  Month clue. It's all about how much sunlight
• 8:45
  we see on it. The answer is the moon appears
• 8:52
  to change shape or go through phases because of how sunlight
• 8:57
  shines on it as it orbits Earth. We see different amounts of the
• 9:01
  lit up part of the moon each night.
• 9:03
  Now here's a question about temperature.
• 9:07
  Do you know why you can see your breath on a cold day?
• 9:10
  Here's your clue. Think about what's in your
• 9:12
  breath and the cold air. The answer is you can see your
• 9:20
  breath on cold days because your warm breath is full of water
• 9:24
  vapor when it. Hits the cold air.
• 9:27
  The vapor cools quickly and turns into tiny droplets, making
• 9:31
  a visible mist. How about a question on
• 9:34
  electricity? Do you know why birds can sit on
• 9:37
  power lines without getting shocked?
• 9:39
  Clue. It's about the path electricity
• 9:42
  takes. The answer is birds don't get
• 9:49
  shocked because both of their feet are on the same wire, so
• 9:53
  electricity does not flow through their bodies.
• 9:56
  If they touched another wire or the ground at the same time, it
• 10:00
  would be dangerous. Here's a question about the
• 10:02
  seasons. Do you know why we have
• 10:05
  different seasons on Earth? Clue.
• 10:07
  It has to do with the way our planet is tilted.
• 10:14
  The answer is we have seasons because Earth is tilted on its
• 10:18
  axis as it orbits around the sun.
• 10:21
  This tilt causes different parts of Earth to get more sunlight at
• 10:24
  different times of the year. Let's try something about the
• 10:27
  senses. Do you know why onions make you
• 10:30
  cry when you cut them? Clue.
• 10:32
  It's about something released into the air.
• 10:39
  The answer is onions make you cry because they release a
• 10:43
  special gas. When cut, this gas mixes with
• 10:46
  the moisture in your eyes and forms a mild acid, which causes
• 10:50
  your eyes to sting and water. Now it's time for the Super
• 10:54
  challenge. This one is a bit trickier, so
• 10:58
  put on your thinking cap. Do you know why some animals
• 11:01
  like bats can see in the dark? Here's.
• 11:04
  Your clue? They use sound, not light, to
• 11:07
  find their way. The answer is some animals use
• 11:15
  echolocation to see in the dark. They make sounds that bounce off
• 11:19
  objects, and by listening to the echoes, they can figure out
• 11:23
  where things are around them. That's it for today's DYKY.
