Today, you built a fun, colorful, and interactive project
while you learned about an important
computer science concept: variables.
Variables help people collect and utilize
information, or data.
For example, computer scientists designed tools
to help forecast the weather,
such as the ones described in this video.
NASA satellites orbiting the Earth
relay immense amounts of data back to scientists
on the ground, who can then enter that data
into computer models simulations.
We have then equations.
And then we have computer code,
which solves those equations on a day-to-day basis.
The data meteorologists collect
can be stored as variables.
Computer scientists use those variables
in programs that help determine the likelihood
of a given weather pattern.
Scientists and meteorologists use computer science
to collect and analyze data,
allowing them to forecast the weather.
Industries such as agriculture, emergency services,
and airlines depend on these weather forecasts.
Knowledge of the weather helps people to plan better,
keeps the public safe, and save money.
This is one example of how computer science
directly impacts the world in which you live.
Next time, you will learn how to make an art application
that allows you to create graffiti artwork.
Until then have fun creating and coding.
