1 00:00:00,000 --> 00:00:09,480 Hi, I'm Linda Zeromski from Mr. Tyson's 6th grade class at Tubal Dream Academy in Newport 2 00:00:09,480 --> 00:00:10,680 News, Virginia. 3 00:00:10,680 --> 00:00:12,960 What is the problem you're trying to solve? 4 00:00:12,960 --> 00:00:16,960 We wanted to know if the size of the airplane's wings affected its flight. 5 00:00:16,960 --> 00:00:19,000 What was your experiment? 6 00:00:19,000 --> 00:00:21,800 Our teacher, Mr. Tyson, set up the test area. 7 00:00:21,800 --> 00:00:23,320 Let's take a look at it. 8 00:00:23,320 --> 00:00:28,560 The test area has a hinge with a 62-centimeter stick attached with a pushpin on the other 9 00:00:28,560 --> 00:00:29,560 end. 10 00:00:29,560 --> 00:00:32,120 The stick should go up and down freely. 11 00:00:32,120 --> 00:00:33,640 Here is our test fuselage. 12 00:00:33,640 --> 00:00:38,120 We will be attaching to it different size wings that we have made. 13 00:00:38,120 --> 00:00:41,040 Why has the propeller been removed? 14 00:00:41,040 --> 00:00:46,040 We are going to be using a fan to create our thrust instead of the propeller. 15 00:00:46,040 --> 00:00:50,960 However, paper clips have been added to replace the weight of the propeller so that we keep 16 00:00:50,960 --> 00:00:52,840 our variables the same. 17 00:00:52,840 --> 00:00:55,240 Let's test it and see how it lifts. 18 00:00:55,240 --> 00:00:59,320 Okay, we attached the small wing to the fuselage like this. 19 00:00:59,400 --> 00:01:01,920 Now we turn the fan to a low speed. 20 00:01:01,920 --> 00:01:06,320 I think we need to turn it up to medium because the wing is not lifting much. 21 00:01:10,320 --> 00:01:12,120 Now look at it lift. 22 00:01:12,120 --> 00:01:18,320 It is stable now, so add paper clips one at a time until the plane will no longer fly. 23 00:01:18,320 --> 00:01:25,280 Wow, it held five paper clips and each paper clip is about 1.5 grams. 24 00:01:25,280 --> 00:01:29,280 So our total weight added was 7.5 grams. 25 00:01:29,280 --> 00:01:32,280 We decided to do the experiment at least two more times. 26 00:01:40,280 --> 00:01:44,280 Now we need to take an average of all the trials for each wing. 27 00:01:44,280 --> 00:01:46,280 Remember how to get an average? 28 00:01:46,280 --> 00:01:51,280 Just add up all the numbers and divide by the total number of numbers you added. 29 00:01:51,280 --> 00:01:54,280 Now we are ready to test the other wing. 30 00:01:54,280 --> 00:01:58,280 Remember, keep all the variables the same during the experiment. 31 00:01:58,280 --> 00:02:02,280 The only variable that will change is the size of the wing. 32 00:02:03,280 --> 00:02:05,280 Let's take a look at our data. 33 00:02:05,280 --> 00:02:09,280 The small wing held 7.5 grams of paper clips, 34 00:02:09,280 --> 00:02:12,280 while the larger wing held 18 grams of paper clips. 35 00:02:12,280 --> 00:02:18,280 So that means that since the larger wing lifted the most weight, it has the best lift. 36 00:02:18,280 --> 00:02:20,280 Newport News isn't that far away. 37 00:02:20,280 --> 00:02:22,280 Maybe we can test our new hypothesis. 38 00:02:22,280 --> 00:02:26,280 Our new hypothesis is if you change the size of the wings, 39 00:02:26,280 --> 00:02:28,280 then it will affect the lift of the plane. 40 00:02:31,280 --> 00:02:33,280 We're not seeing any lift here, that's for sure. 41 00:02:33,280 --> 00:02:36,280 We need these planes to soar. That's if we want to win the competition. 42 00:02:36,280 --> 00:02:40,280 We need my man Jackie Chan to be here. He's a human flying machine. 43 00:02:40,280 --> 00:02:42,280 Yeah, right. What could he do? 44 00:02:42,280 --> 00:02:45,280 He's so cool. I just saw him in a movie and he flies right through the air. 45 00:02:45,280 --> 00:02:47,280 I bet he knows all about the force of lift. 46 00:02:47,280 --> 00:02:49,280 That's fake. That's just a movie. 47 00:02:49,280 --> 00:02:52,280 No way. If he was here, he would help us win that competition. 48 00:02:57,280 --> 00:03:01,280 Who's that? Is that who I think it is? 49 00:03:01,280 --> 00:03:03,280 It's him, Jackie Chan. 50 00:03:03,280 --> 00:03:05,280 You mean the martial arts master? 51 00:03:18,280 --> 00:03:19,280 Nice to meet you, Mr. Chan. 52 00:03:19,280 --> 00:03:20,280 Nice to meet you. 53 00:03:20,280 --> 00:03:21,280 Hi. 54 00:03:21,280 --> 00:03:22,280 Nice to meet you. 55 00:03:23,280 --> 00:03:24,280 Nice to meet you, Mr. Chan. 56 00:03:24,280 --> 00:03:25,280 Nice to meet you. 57 00:03:25,280 --> 00:03:26,280 Hi. 58 00:03:26,280 --> 00:03:28,280 Hi, hi, hi. I hear you guys need my help. 59 00:03:28,280 --> 00:03:29,280 Uh-huh. 60 00:03:29,280 --> 00:03:31,280 What do you do when you're faced with a challenge? 61 00:03:31,280 --> 00:03:33,280 I just never give up. 62 00:03:37,280 --> 00:03:43,280 Think about it before I do the stunt, but I'm not going to do it today. I'll do it tomorrow. 63 00:03:43,280 --> 00:03:44,280 Can you help us? 64 00:03:44,280 --> 00:03:48,280 I'm going to help you to build super-duper airplane. Okay? 65 00:03:52,280 --> 00:03:53,280 Whoa. 66 00:03:57,280 --> 00:03:58,280 Okay. 67 00:04:02,280 --> 00:04:03,280 Wow. 68 00:04:03,280 --> 00:04:04,280 See? 69 00:04:11,280 --> 00:04:13,280 Do you think studying is important? 70 00:04:13,280 --> 00:04:15,280 When I was 17, I got out of school. 71 00:04:15,280 --> 00:04:21,280 Then slowly, slowly, I find out education is more important than doing the punch and kicking. 72 00:04:21,280 --> 00:04:24,280 Good luck. I know you guys will be winners. Okay? Bye-bye. 73 00:04:24,280 --> 00:04:25,280 Bye. 74 00:04:25,280 --> 00:04:26,280 Thank you. 75 00:04:26,280 --> 00:04:27,280 Thank you. 76 00:04:27,280 --> 00:04:28,280 See you, Jackie Chan. 77 00:04:28,280 --> 00:04:30,280 That was really him. 78 00:04:30,280 --> 00:04:34,280 It sure was.
