| 00:09 | we've been talking about the stars in space and the | |
| 00:12 | habitats on earth and the conservation of mass and all | |
| 00:14 | kinds of stuff . And while I love talking about | |
| 00:16 | those things , there's one topic we haven't covered in | |
| 00:19 | a while that I miss engineering and cartoon me really | |
| 00:23 | missed wearing this cool iron ran outfit looking good little | |
| 00:26 | Sabrina so far . We've talked about what engineers do | |
| 00:30 | and the process that they follow when they're , you | |
| 00:32 | know , engineering stuff . We've also devoted to lessons | |
| 00:35 | to the super important first step of the engineering process | |
| 00:38 | defining the problem problems . They're the worst . But | |
| 00:42 | you know what's the best ? I mean after pancake | |
| 00:45 | solutions , solutions are great . Which brings us to | |
| 00:48 | our big question , is there just one solution for | |
| 00:51 | every problem ? Yeah . For those of you who | |
| 00:57 | don't remember what an engineer is or didn't watch that | |
| 01:00 | lesson and um hi you totally should . An engineer | |
| 01:04 | is a person who designs and builds things to solve | |
| 01:06 | specific problems . The engineering process is a series of | |
| 01:09 | steps that engineers used to guide them as they work | |
| 01:12 | toward a solution for whatever their particular problem is . | |
| 01:15 | Now , speaking of problems , remember this place ? | |
| 01:18 | The problem we faced earlier was getting across this gigantic | |
| 01:21 | gorge in one piece more . Specifically , our problem | |
| 01:25 | was how do we fly across this huge gorge ? | |
| 01:27 | Since there was no bridge to cross and it was | |
| 01:29 | too deep to climb down one side and up the | |
| 01:31 | other ? We decided a hang glider was one possible | |
| 01:33 | way to soar across the gap , which was pretty | |
| 01:36 | clever , I have to say . But if we | |
| 01:38 | want to really think like engineers , we should try | |
| 01:41 | to come up with more than just one solution to | |
| 01:43 | this problem , or more than one way to fly | |
| 01:45 | across this gorge , think we can do it . | |
| 01:47 | We totally got this . Let's review our checklist from | |
| 01:54 | the earlier lessons on what a successful solution to this | |
| 01:56 | problem looks like number one , was that our solution | |
| 01:59 | should get us to the other side alive , yep | |
| 02:02 | , that's a big number to it . The thing | |
| 02:04 | that gets us to the other side should be something | |
| 02:06 | we currently have or can easily get our hands on | |
| 02:09 | . And lastly number three , was that whatever our | |
| 02:11 | solution is , it's something we can ideally reuse once | |
| 02:14 | we're on the other side . So other than our | |
| 02:15 | hang glider solution from last time , what else can | |
| 02:18 | we think of ? Well , let's say we took | |
| 02:20 | this camping trip to celebrate a birthday . So , | |
| 02:22 | we brought along a pack of balloons to blow up | |
| 02:24 | and decorate the tent with , luckily we haven't inflated | |
| 02:27 | them just yet . So what if we use the | |
| 02:29 | balloons to lift the tent or maybe just me and | |
| 02:31 | carry me over the gorge , kind of like in | |
| 02:33 | the movie up . But with cartoon , me instead | |
| 02:35 | of carl and russell , that idea . Plus the | |
| 02:37 | tent hang glider gives us two possible solutions to our | |
| 02:40 | gorge problem three is better than two , I say | |
| 02:42 | . So can we come up with one more ? | |
| 02:44 | Like any good camper ? We came on this trip | |
| 02:46 | prepared for anything from birthdays to bad weather , bad | |
| 02:49 | weather , like rain . So of course we've got | |
| 02:52 | an umbrella handy . Hm I wonder if we get | |
| 02:54 | a good running head start , if we could get | |
| 02:56 | enough lift to float or fly across the gorge . | |
| 02:59 | Hey , it worked for mary Poppins anyhow . This | |
| 03:02 | gorge problem as tricky as it is actually does have | |
| 03:05 | more than one possible solution , but are they all | |
| 03:08 | really possible ? We don't know yet if they'll actually | |
| 03:11 | work because that's what the evaluating stages for . So | |
| 03:14 | in the meantime , guys definitely don't try any of | |
| 03:18 | these solutions at home . Okay . I'd prefer . | |
| 03:20 | And I think your parents would agree that you kept | |
| 03:22 | your feet on the ground where they belong . Cool | |
| 03:26 | , cool . So is there just one possible solution | |
| 03:33 | to this problem ? Say it with me now ? | |
| 03:35 | No . There are usually many potential ways to solve | |
| 03:37 | any given problem , but is one solution even better | |
| 03:40 | than another , is one of our three flying solutions | |
| 03:43 | better than the other to the answer to that question | |
| 03:46 | is coming up next time . See us soon . | |
| 03:48 | Engineers and training . |
