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