Congratulations on coding your cooperative game.
I hope you and your friend
had as much fun as we did.
Hey, look at this bonus star.
I know, more points, right?
That's right.
Today you learned how to use variables.
Variables are a way for computers
to store data that change.
Computer scientists can use variables
to help save the lives of endangered animals.
In Amboseli National Park, Kenya,
elephants are fit with GPS collars.
These collars collect data
about the elephant's location and roaming habits.
That data is sent to computers and stored in variables.
Using that information, the park can more
effectively map out the space the elephants need.
And place rangers around the park
to protect the elephants from poachers.
Elephants aren't the only endangered animals
that GPS collars have helped.
That's right.
GPS collars have been used to track wolves
in Yellowstone National Park, Cross River gorillas
in Africa and tigers in Nepal.
The collars provide information to help protect
animals and to create a habitat where they can thrive.
Conservationists and computer scientists team up
to use variables and help protect endangered species.
It's pretty important.
It's awesome.
Next time at Google CS First
we will create a company together.
You and your friend will get to imagine
and invent a product.
And create advertisements
for your invention in Scratch.
Until next time, have fun creating.
And coding.
Bye guys. See ya.
