Hi, I'm Bowie. I am in Ms. Schwartz's fourth grade class at Temple Elementary School in Silver Spring, Maryland. 00:00:00
Hi, we read on the internet that you're participating in a NASA project with Space Seeds. 00:00:08
Yes, we are growing Arabidopsis plants. 00:00:13
What are Arabidopsis plants? 00:00:16
They are more commonly known as mustard weed. 00:00:18
It has a life cycle of six weeks from seed to seed. 00:00:21
It is easy to grow in small places. Also, it produces a lot of seeds. 00:00:25
That makes it a great test plant to be grown in space. 00:00:30
How do you get Space Seeds? 00:00:33
We participate in a NASA experiment through a company called Space Explorers, Inc. 00:00:35
They get the seeds from NASA and distribute to teachers who have signed up for the program. 00:00:41
Why does NASA want children to grow the Space Seeds on Earth? 00:00:46
Whenever you are doing an experiment, you have to have a control group. 00:00:50
We grow the plants as the control group for the experiment on the International Space Station. 00:00:54
We learn about controls from the scientific method. 00:00:59
We measure the plants as they grow and keep accurate records. 00:01:02
This gives NASA a reference point of normal growth and reproduction 00:01:05
to compare with the plants grown on the International Space Station. 00:01:09
Why is that important? 00:01:13
Scientists need to make sure that the plants are growing and producing just like they do on Earth. 00:01:15
Is there anything else that the plants do for the astronauts in space? 00:01:21
Yes, they create a bioregenerative life support system. 00:01:25
What is that? 00:01:29
It's a system that uses plants rather than machines. 00:01:31
The plants release oxygen, help recycle drinking water, and create water vapor through transpiration. 00:01:34
Just like Mr. Gruner mentioned. 00:01:41
We definitely need a bioregenerative system in our habitat. 00:01:43
Thanks for helping us. 00:01:47
You're welcome! 00:01:48
And good luck on your project! 00:01:49
