0:00:00.179,0:00:05.119 Unplugged Activity | Real Life Algorithms:[br]Paper Airplanes 0:00:07.179,0:00:10.059 This lesson is called Real Life Algorithms. 0:00:10.070,0:00:15.140 Algorithms describe things[br]that people do everyday. Cookie recipes and 0:00:15.140,0:00:20.369 directions for building a birdhouse are both[br]everyday algorithms. Today we're gonna make, 0:00:20.369,0:00:27.279 create, and test an algorithm for a paper[br]airplane. But first, we need to break this 0:00:27.279,0:00:32.590 big project into easy to follow small steps.[br]For making a paper airplane, we need to decide 0:00:32.590,0:00:37.390 what steps to take and in what order to take[br]them. You'll create your algorithm by first 0:00:37.390,0:00:42.880 cutting apart the pictures. Next, you'll select[br]the 6 pictures that show the steps needed 0:00:42.880,0:00:47.730 to make a paper airplane and arrange those[br]pictures in the correct order. After you have 0:00:47.730,0:00:52.140 everything in order, you will trade algorithms[br]with another student team to test out the 0:00:52.140,0:00:57.020 algorithm to see if the algorithm works. A[br]well designed algorithm is super important 0:00:57.020,0:01:01.320 to making the best paper airplane. 0:01:06.740,0:01:10.000 When we want to make chocolate, there are many big 0:01:10.000,0:01:15.240 steps to that process. And each of those big[br]steps has its own set of smaller steps. And 0:01:15.240,0:01:19.290 there are different recipes, or algorithms,[br]depending on how we want the chocolate to 0:01:19.290,0:01:23.990 taste. Each step is important, even the small[br]ones. So without one step, the rest of them 0:01:23.990,0:01:30.729 cannot be completed. Creating algorithms that[br]others can understand is really important. 0:01:30.729,0:01:34.630 That's why each step has to be written down,[br]so no matter who does it, the result is the same.
