1 00:00:00,000 --> 00:00:04,400 Unplugged Activity Real Life Algorithms: Planting a Seed 2 00:00:05,240 --> 00:00:07,340 algorithm 3 00:00:07,860 --> 00:00:09,620 This lesson is called planting 4 00:00:09,639 --> 00:00:14,790 a seed, and it's going to help us understand algorithms. Algorithms are specific instructions 5 00:00:14,790 --> 00:00:19,899 that explain the order in which to do something. Even every day things like eating breakfast 6 00:00:19,899 --> 00:00:25,380 or brushing your teeth are algorithms that require small steps to get a job done. Computers 7 00:00:25,380 --> 00:00:30,659 can be really smart, but they can only understand you if you tell them exactly what you want, 8 00:00:30,659 --> 00:00:35,230 step by step. The great thing about algorithms is that if you follow the instructions in 9 00:00:35,230 --> 00:00:39,519 order, you can do something that you didn't know how to do ahead of time. It's like following 10 00:00:39,519 --> 00:00:45,199 a recipe. Today we're going to plant our own seeds using an algorithm. So first we have 11 00:00:45,199 --> 00:00:52,199 to fill the pot with soil right? I don't think we have to put glue on the seed. Right. Create 12 00:00:52,530 --> 00:00:58,129 your own algorithm by cutting apart the pictures. Select the pictures that show steps in planting 13 00:00:58,129 --> 00:01:03,789 a seed, and then arrange those pictures in the correct order. Now, it's time for you 14 00:01:03,789 --> 00:01:09,530 to see if your algorithm works. Follow the steps in the algorithm very carefully. Are 15 00:01:09,530 --> 00:01:14,670 they in the correct order? Did you succeed in planting a seed by following the algorithm? 16 00:01:14,670 --> 00:01:19,130 It's like programming with pictures! 17 00:01:19,130 --> 00:01:22,800 When we want to make chocolate, there are many 18 00:01:22,810 --> 00:01:28,219 big steps to that process. And each of those big steps has its own set of smaller steps. 19 00:01:28,219 --> 00:01:32,119 And there are different recipes, or algorithms, depending on how we want the chocolate to 20 00:01:32,119 --> 00:01:36,969 taste. Each step is important, even the small ones. So without one step, the rest of them 21 00:01:36,969 --> 00:01:43,700 could not be completed. Creating algorithms that others can understand is really important. 22 00:01:43,700 --> 00:01:47,320 That's why each step has to be written down so that no matter who does it, the result 23 00:01:47,320 --> 00:01:47,679 is the same.
