WEBVTT 00:00:00.179 --> 00:00:05.119 Unplugged Activity | Real Life Algorithms: Paper Airplanes 00:00:07.179 --> 00:00:10.059 This lesson is called Real Life Algorithms. 00:00:10.070 --> 00:00:15.140 Algorithms describe things that people do everyday. Cookie recipes and 00:00:15.140 --> 00:00:20.369 directions for building a birdhouse are both everyday algorithms. Today we're gonna make, 00:00:20.369 --> 00:00:27.279 create, and test an algorithm for a paper airplane. But first, we need to break this 00:00:27.279 --> 00:00:32.590 big project into easy to follow small steps. For making a paper airplane, we need to decide 00:00:32.590 --> 00:00:37.390 what steps to take and in what order to take them. You'll create your algorithm by first 00:00:37.390 --> 00:00:42.880 cutting apart the pictures. Next, you'll select the 6 pictures that show the steps needed 00:00:42.880 --> 00:00:47.730 to make a paper airplane and arrange those pictures in the correct order. After you have 00:00:47.730 --> 00:00:52.140 everything in order, you will trade algorithms with another student team to test out the 00:00:52.140 --> 00:00:57.020 algorithm to see if the algorithm works. A well designed algorithm is super important 00:00:57.020 --> 00:01:01.320 to making the best paper airplane. 00:01:06.740 --> 00:01:10.000 When we want to make chocolate, there are many big 00:01:10.000 --> 00:01:15.240 steps to that process. And each of those big steps has its own set of smaller steps. And 00:01:15.240 --> 00:01:19.290 there are different recipes, or algorithms, depending on how we want the chocolate to 00:01:19.290 --> 00:01:23.990 taste. Each step is important, even the small ones. So without one step, the rest of them 00:01:23.990 --> 00:01:30.729 cannot be completed. Creating algorithms that others can understand is really important. 00:01:30.729 --> 00:01:34.630 That's why each step has to be written down, so no matter who does it, the result is the same.
