1 00:00:00,179 --> 00:00:05,119 Unplugged Activity | Real Life Algorithms: Paper Airplanes 2 00:00:07,179 --> 00:00:10,059 This lesson is called Real Life Algorithms. 3 00:00:10,070 --> 00:00:15,140 Algorithms describe things that people do everyday. Cookie recipes and 4 00:00:15,140 --> 00:00:20,369 directions for building a birdhouse are both everyday algorithms. Today we're gonna make, 5 00:00:20,369 --> 00:00:27,279 create, and test an algorithm for a paper airplane. But first, we need to break this 6 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 7 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 8 00:00:37,390 --> 00:00:42,880 cutting apart the pictures. Next, you'll select the 6 pictures that show the steps needed 9 00:00:42,880 --> 00:00:47,730 to make a paper airplane and arrange those pictures in the correct order. After you have 10 00:00:47,730 --> 00:00:52,140 everything in order, you will trade algorithms with another student team to test out the 11 00:00:52,140 --> 00:00:57,020 algorithm to see if the algorithm works. A well designed algorithm is super important 12 00:00:57,020 --> 00:01:01,320 to making the best paper airplane. 13 00:01:06,740 --> 00:01:10,000 When we want to make chocolate, there are many big 14 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 15 00:01:15,240 --> 00:01:19,290 there are different recipes, or algorithms, depending on how we want the chocolate to 16 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 17 00:01:23,990 --> 00:01:30,729 cannot be completed. Creating algorithms that others can understand is really important. 18 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.
