0:00:00.000,0:00:04.400 Unplugged Activity[br]Real Life Algorithms: Planting a Seed 0:00:05.240,0:00:07.340 algorithm 0:00:07.860,0:00:09.620 This lesson is called planting 0:00:09.639,0:00:14.790 a seed, and it's going to help us understand[br]algorithms. Algorithms are specific instructions 0:00:14.790,0:00:19.899 that explain the order in which to do something.[br]Even every day things like eating breakfast 0:00:19.899,0:00:25.380 or brushing your teeth are algorithms that[br]require small steps to get a job done. Computers 0:00:25.380,0:00:30.659 can be really smart, but they can only understand[br]you if you tell them exactly what you want, 0:00:30.659,0:00:35.230 step by step. The great thing about algorithms[br]is that if you follow the instructions in 0:00:35.230,0:00:39.519 order, you can do something that you didn't[br]know how to do ahead of time. It's like following 0:00:39.519,0:00:45.199 a recipe. Today we're going to plant our own[br]seeds using an algorithm. So first we have 0:00:45.199,0:00:52.199 to fill the pot with soil right? I don't think[br]we have to put glue on the seed. Right. Create 0:00:52.530,0:00:58.129 your own algorithm by cutting apart the pictures.[br]Select the pictures that show steps in planting 0:00:58.129,0:01:03.789 a seed, and then arrange those pictures in[br]the correct order. Now, it's time for you 0:01:03.789,0:01:09.530 to see if your algorithm works. Follow the[br]steps in the algorithm very carefully. Are 0:01:09.530,0:01:14.670 they in the correct order? Did you succeed[br]in planting a seed by following the algorithm? 0:01:14.670,0:01:19.130 It's like programming with pictures! 0:01:19.130,0:01:22.800 When we want to make chocolate, there are many 0:01:22.810,0:01:28.219 big steps to that process. And each of those[br]big steps has its own set of smaller steps. 0:01:28.219,0:01:32.119 And there are different recipes, or algorithms,[br]depending on how we want the chocolate to 0:01:32.119,0:01:36.969 taste. Each step is important, even the small[br]ones. So without one step, the rest of them 0:01:36.969,0:01:43.700 could not be completed. Creating algorithms[br]that others can understand is really important. 0:01:43.700,0:01:47.320 That's why each step has to be written down[br]so that no matter who does it, the result 0:01:47.320,0:01:47.679 is the same.
