Now that we've learned about some of the parts of the ISS, 00:00:00

how would you like to build your own model? 00:00:03

But wait, there's a catch. 00:00:05

You have a question. 00:00:07

NASA Connect traveled northwest to San Francisco, California 00:00:08

for this program's classroom activity. 00:00:12

Hi, we're from Alice Longview in San Francisco, California. 00:00:14

NASA Connect has asked us to show you this program's classroom activity. 00:00:21

You'll work in groups to design an alternative space station. 00:00:28

Then you'll create a model using everyday items 00:00:31

like aluminum cans, cereal boxes, and straws. 00:00:33

You'll analyze and interpret data to determine the best design 00:00:37

based on budget restrictions, weight, and placement of the parts that you construct. 00:00:40

Teachers, make sure you download the lesson guide for this activity 00:00:44

from the NASA Connect website. 00:00:47

In it, you'll find a list of materials, directions, and student worksheets. 00:00:49

We won't cover everything in the next few minutes, 00:00:54

but we will give you a general idea about how it all goes together. 00:00:56

To begin, your teacher will display the labeled picture of the ISS 00:01:00

as it may appear upon completion. 00:01:04

Discuss each component and its functions. 00:01:06

Okay, the National Aeronautics and Space Administration needs your help. 00:01:08

They want you to design and build a model of an international space station, 00:01:13

and your budget is $1 billion. 00:01:17

Your first step is to construct the components. 00:01:20

For your station, you'll make photovoltaic, or PV, arrays 00:01:23

using transparency film and craft sticks. 00:01:26

The thermal radiators used to cool the station are made with aluminum foil. 00:01:29

A cardboard tube serves as the docking port. 00:01:33

The habitation and laboratory modules are made with aluminum cans. 00:01:36

The truss segments used to connect the modules are made from foam food trays. 00:01:40

A small cereal box represents the core module of your space station. 00:01:47

Buttons are used to simulate the attitude control thrusters. 00:01:51

And for the robotic arm, use a flexible drinking straw. 00:01:55

Find the total mass and total cost of each component 00:01:58

using formulas provided in the lesson guide, 00:02:01

and record the values on your student worksheet. 00:02:04

Before you design and assemble your space station, 00:02:07

you need to pay close attention to the constraints listed in Appendix A. 00:02:09

Okay, remember the budget for the space station is $1 billion. 00:02:13

If you break a component or a section of the space station, 00:02:17

you have to purchase a new one. 00:02:20

Now decide how all the components of your space station will be arranged. 00:02:23

Make a sketch before you start your actual assembly, 00:02:27

and don't forget your constraints. 00:02:30

Use tape and glue to put it all together. 00:02:32

When your space station is assembled, the next step is to calculate the total mass. 00:02:34

Because the ISS is being assembled in orbit, 00:02:38

and not here on Earth, it's impossible to get the total mass at one time. 00:02:41

Therefore, NASA determines the total mass 00:02:45

by taking the sum of the individual components before they are launched into space. 00:02:48

Since we are working with a model, there are two ways to calculate the total mass. 00:02:52

First, take the sum of the mass of the individual components. 00:02:56

Then use your balance to weight your completed model. 00:02:59

Find the difference between the two masses 00:03:02

and compare the accuracy of massing individual pieces 00:03:04

with the mass of the entire space station. 00:03:07

If the difference is greater than 5 grams, 00:03:10

you'll be charged a tax of $1 million per gram. 00:03:12

If the difference is less than or equal to 5 grams, 00:03:15

then the space tax will not apply. 00:03:18

Record any space tax on the data table. 00:03:20

Finally, calculate the total cost of your space station 00:03:23

by taking the sums of costs for all your components 00:03:26

and any space tax you owe. 00:03:29

Did you meet your budget, or are you over budget? 00:03:31

We would like to thank the San Jose AIAA student branch for helping us with this activity. 00:03:34
