Must be in season. 380 00:22:38,108 --> 00:22:41,903 I could use some… sparkly rainbow juice! 381 00:22:45,573 --> 00:22:48,368 Sparkling rainbow juice is so refreshing. 382 00:22:48,868 --> 00:22:50,078 Mooshu wants some too. 383 00:22:51,996 --> 00:22:54,040 Now, I think it’s time for the… 384 00:22:54,124 --> 00:22:56,584 Unicorn Stampede! 385 00:23:06,553 --> 00:23:10,640 I have an idea. Let’s meet another scientist. Come on. 386 00:23:14,978 --> 00:23:18,189 Hi, I’m Eletrice Harris and I’m an architect. 387 00:23:18,273 --> 00:23:21,276 Today, I’m gonna show you one of the houses I designed. 388 00:23:21,359 --> 00:23:22,193 Let’s go! 389 00:23:22,277 --> 00:23:25,238 Any building or structure that you walk into, 390 00:23:25,321 --> 00:23:27,073 an architect has designed it. 391 00:23:27,157 --> 00:23:31,786 It could be a hospital, a school, a library, your home. 392 00:23:31,870 --> 00:23:36,666 So for every structure that we design, we do a set of plans, 393 00:23:36,749 --> 00:23:39,210 and these are called blueprints. 394 00:23:39,294 --> 00:23:43,256 And so the blueprints, it shows the walls, it shows the windows, 395 00:23:43,339 --> 00:23:44,966 it shows the doors. 396 00:23:45,049 --> 00:23:47,469 We even put in where the toilet should be. 397 00:23:49,137 --> 00:23:53,600 Just like we have skeletons in our body, buildings have the same thing. 398 00:23:53,683 --> 00:23:55,768 We call this our skeletal frame. 399 00:23:57,270 --> 00:24:00,732 One of the most important things when building a structure or a house 400 00:24:00,815 --> 00:24:03,359 is to make sure it will withstand the elements. 401 00:24:03,443 --> 00:24:06,112 The rain, the wind, storms. 402 00:24:06,196 --> 00:24:12,744 So the two structural components that are important to making a structure sound 403 00:24:12,827 --> 00:24:16,331 are the beams, which are horizontal, 404 00:24:16,414 --> 00:24:18,374 and columns that are vertical. 405 00:24:19,042 --> 00:24:21,586 This is what a doorway looks like in plan, 406 00:24:21,669 --> 00:24:24,464 and this is what it looks like when we frame it out. 407 00:24:24,547 --> 00:24:29,093 So this would be our beam and these are our posts for the doorway. 408 00:24:30,637 --> 00:24:33,515 So here’s a finished product of a doorway. 409 00:24:33,598 --> 00:24:37,894 And if you could imagine that that beam is across the top 410 00:24:37,977 --> 00:24:40,021 and the posts are along the sides. 411 00:24:42,440 --> 00:24:43,733 Fun fact! 412 00:24:43,816 --> 00:24:45,818 Architecture was a part of the Olympics. 413 00:24:45,902 --> 00:24:50,281 To compete, you had to design a sports-related structure. 414 00:24:53,743 --> 00:24:56,454 Wasn’t that cool? Science is the best!
