00:00the code world alara loved to watch her dad work his computer screen was a magical window
00:07full of glowing words and pictures what's in there she'd ask her little finger pointing at the screen
00:15one day when the screen was dark alara couldn't resist she reached out and gently tapped the
00:21glass boop a tiny door made of shimmering blue light popped open right in the middle of the screen
00:28alara giggled and peeked inside the door grew bigger and bigger until she could step right through
00:35she found herself in a place made of light and logic where glowing lines zipped and zoomed hello
00:42said a little voice it was a tiny sparkling creature named pixel welcome to the code world pixel chirped
00:50everything here moves with a plan see that path he pointed to a trail of glowing squares that led to a
00:56sparkling star to get there we have to give instructions this is called a sequence pixel
01:04explained it's a list of steps one after the other he gave alara three little cards one with an arrow
01:11pointing forward one with a spinning arrow and one with a forward arrow again try to get our little
01:17friend a sprite to the star alara placed the cards in a row forward turn forward the sprite zipped along
01:26the path following her instructions perfectly until it reached the star ding the star twinkled brightly
01:33you did it pixel cheered next they came to a field of bright digital flowers these flowers are thirsty
01:42pixel said we could give the water instruction one by one but that would take forever this is
01:49where we use a loop he explained we tell the computer to repeat the same thing over and over again
01:56elara placed one water card inside a special repeat card for every flower she said whoosh the sprite zipped
02:05from flower to flower watering each one in a flash the flowers perked up and glowed with happy colors
02:12that was so much faster elara exclaimed they reached a giant gap in the path with a button on one side
02:20to cross this we need a condition pixel said we have to tell the computer if this happens then do that
02:29elara thought hard she placed a card that said if button is pressed and another that said then build bridge
