1 00:00:00,000 --> 00:00:11,000 Hi, we're students at Williams Technology Middle School here in Luntzville, Alabama. 2 00:00:11,000 --> 00:00:15,000 NASA Connect asked us to show you this program's hands-on activity. 3 00:00:15,000 --> 00:00:21,000 You can download the Educator Guide and a list of materials from the NASA Connect website. 4 00:00:21,000 --> 00:00:23,000 Here are the main objectives. 5 00:00:23,000 --> 00:00:29,000 Students will gather statistical data, find the optimum ratio for best vehicle performance, 6 00:00:29,000 --> 00:00:34,000 explore mathematical problem solving, and explore mathematical models through graphing. 7 00:00:34,000 --> 00:00:36,000 Here are some terms you need to know. 8 00:00:36,000 --> 00:00:40,000 Propulsion is the act of driving forward or away. 9 00:00:40,000 --> 00:00:46,000 Thrust is a force produced by a rocket engine in reaction to a high-velocity exhaust gas. 10 00:00:46,000 --> 00:00:48,000 Kinetic energy is energy in motion. 11 00:00:48,000 --> 00:00:52,000 And momentum is a directional measurement of an object's motion, 12 00:00:52,000 --> 00:00:56,000 its tendency to continue moving in a particular direction. 13 00:00:56,000 --> 00:00:57,000 Good morning, class. 14 00:00:57,000 --> 00:00:59,000 Good morning, Ms. Smith. 15 00:00:59,000 --> 00:01:06,000 Today, NASA has asked us to gather statistical data so that we can determine the optimum ratio of our VSV rocket. 16 00:01:06,000 --> 00:01:08,000 Students will organize into groups of four, 17 00:01:08,000 --> 00:01:16,000 with each student taking on one of four jobs as prelaunch officer, launch officer, data recorder, and measurement technician. 18 00:01:16,000 --> 00:01:19,000 Roles can be rotated after every trial. 19 00:01:19,000 --> 00:01:25,000 Each group will construct the launch facility by placing 20 meters of masking tape on the ground in a straight line. 20 00:01:25,000 --> 00:01:29,000 Divide the length of masking tape into 10-centimeter intervals. 21 00:01:29,000 --> 00:01:32,000 Place the shoebox at one end of the masking tape. 22 00:01:32,000 --> 00:01:35,000 The rocket will be placed against it each time. 23 00:01:35,000 --> 00:01:41,000 It may be necessary for the prelaunch officer in the group to place gravel or dirt inside the box to stabilize it. 24 00:01:41,000 --> 00:01:48,000 Begin testing by using a pushpin to attach a 2-centimeter baking soda packet to the bottom of the cork. 25 00:01:48,000 --> 00:01:52,000 The directions to assemble the baking soda packet can be found in the educator guide. 26 00:01:52,000 --> 00:01:57,000 Remember, each rocket must be filled with 115 milliliters of vinegar. 27 00:01:57,000 --> 00:01:59,000 Try not to get vinegar all over yourself. 28 00:01:59,000 --> 00:02:04,000 Slide the cork with the baking soda packet attached into the neck of the bottle firmly. 29 00:02:04,000 --> 00:02:12,000 The launch officer will rapidly shake the rocket three times to start the reaction of the baking soda and vinegar. 30 00:02:12,000 --> 00:02:16,000 Quickly place the corked end of the rocket against the shoebox and move away. 31 00:02:16,000 --> 00:02:19,000 Lift off. 32 00:02:20,000 --> 00:02:24,000 The measurement technician will call out the distance traveled by the rocket, 33 00:02:24,000 --> 00:02:28,000 and the data recorder will write the distance on the distance data chart. 34 00:02:28,000 --> 00:02:32,000 The prelaunch officer will then prepare the rocket for the next trial. 35 00:02:32,000 --> 00:02:34,000 Repeat until all trials have been completed. 36 00:02:34,000 --> 00:02:39,000 Each group will plot the data onto a graph using a different color for each group. 37 00:02:39,000 --> 00:02:43,000 Students will compare the group's average data and analyze the shape of the graph 38 00:02:43,000 --> 00:02:47,000 to determine the best ratio of baking soda to vinegar. 39 00:02:47,000 --> 00:02:53,000 In this class, in comparing the data, at what point did the recorded data start increasing? 40 00:02:53,000 --> 00:02:54,000 Erica? 41 00:02:54,000 --> 00:02:57,000 It started increasing immediately. 42 00:02:57,000 --> 00:03:02,000 Why would it be important for us to find the optimum amount of fuel to use for any rocket? 43 00:03:02,000 --> 00:03:03,000 Erin? 44 00:03:03,000 --> 00:03:06,000 Because you don't want to carry more or less than you need. 45 00:03:06,000 --> 00:03:10,000 Teachers, if you would like help with the baking soda rocket lesson, 46 00:03:10,000 --> 00:03:16,000 simply enlist the help of your AIAA mentor, who will be glad to help your class with these activities. 47 00:03:16,000 --> 00:03:20,000 AIAA stands for American Institute of Aeronautics and Astronautics. 48 00:03:20,000 --> 00:03:23,000 Boy, those kids looked like they were having fun. 49 00:03:23,000 --> 00:03:27,000 No, Jennifer, I did not say having a blast. 50 00:03:27,000 --> 00:03:31,000 But I wanted to. 51 00:03:31,000 --> 00:03:35,000 The folks at NASA Marshall have an awesome program for next generation explorers 52 00:03:35,000 --> 00:03:38,000 to get a real feel for rocket science. 53 00:03:38,000 --> 00:03:43,000 It's called the Student Launch Initiative, SLI, just like the Space Launch Initiative. 54 00:03:43,000 --> 00:03:50,000 Initiative is the key word because these students design, build, test, launch, 55 00:03:50,000 --> 00:03:55,000 and reuse a rocket carrying a half-pound experiment. 56 00:03:55,000 --> 00:03:59,000 They experience the thrill of seeing their rockets take off 57 00:03:59,000 --> 00:04:02,000 and soar from one and a half to over three kilometers high. 58 00:04:02,000 --> 00:04:04,000 Ascent is good. 59 00:04:04,000 --> 00:04:07,000 Students from Huntsville-area high schools and universities 60 00:04:07,000 --> 00:04:11,000 participated in NASA's first Student Launch Initiative. 61 00:04:11,000 --> 00:04:15,000 Students used math, science, and technology to design and build their rockets, 62 00:04:15,000 --> 00:04:19,000 to develop websites, and to apply budgeting and planning principles. 63 00:04:19,000 --> 00:04:25,000 Five, four, three, two, one. 64 00:04:25,000 --> 00:04:28,000 Igniter. 65 00:04:28,000 --> 00:04:32,000 Igniter.
