Hi, I'm Jennifer Pulley, and welcome to NASA Connect, the show that connects you to the 00:00:00
world of math, science, technology, and NASA. 00:00:08
Today, we're at NASA Glenn Research Center in Cleveland, Ohio, and this is the Zero Gravity 00:00:11
Facility, and it's where NASA conducts microgravity experiments. 00:00:18
You've seen microgravity. 00:00:22
You've seen it in videos of the International Space Station, and on NASA's KC-135. 00:00:24
On today's program, we'll investigate how NASA researchers conduct research in a microgravity 00:00:33
environment. 00:00:38
You'll observe NASA researchers using the math concepts of measurement, ratios, and 00:00:39
graphing to research combustion science, and the importance of fire safety on the International 00:00:44
Space Station. 00:00:49
In your classroom, you'll do a cool hands-on activity to learn more about gravity by collecting, 00:00:51
organizing, graphing, and analyzing data. 00:00:56
And using the instructional technology activity, you will investigate apparent weight to see 00:01:00
how astronauts in space can feel weightless. 00:01:05
NASA researchers use the math concepts of ratios, measurement, and graphing all the 00:01:08
time. 00:01:13
First, let's review ratios. 00:01:14
A ratio is a comparison of two quantities. 00:01:16
For example, NASA Glenn Research Center and NASA Marshall Space Flight Center, which are 00:01:19
the NASA facilities that primarily conduct microgravity research, are two of ten NASA 00:01:24
centers located across the country. 00:01:30
A ratio can be written as a fraction, and it can be written in any form that is equal 00:01:33
or equivalent to that fraction. 00:01:38
So the ratio two-tenths can also be written as two is to ten, twenty percent, twenty-one-hundredths, 00:01:41
and point-two-zero. 00:01:48
When you work with ratios, you can express fractions, decimals, and percentages. 00:01:49
To learn how NASA researchers apply the concept of ratios to the microgravity environment, 00:01:55
let's go see Dr. Roger Crouch. 00:02:00
He's the senior scientist for the International Space Station. 00:02:02
