What Is Computer
Science?
Computer Science
is all about solving
problems…
…and using the computer to
solve some very difficult
problems.
Computer Science is
about problem solving
Lets solve a problem!
In computer science we build Algorithms…
a sequence of steps/instructions to solve a problem
Problem Solving
A farmer has to get a sheep, a
carrot and a wolf over the river
to the grassy field.
BUT he can only take one of
them with him at a time …
Problem Solving
BUT if left alone,
The
wolf will eat
the sheep
The sheep will
eat the carrot

River Alive!

What is Programming?
A
computer can only do what it is told to
do
A
program is a set of instructions
telling a machine what to do
 Programming
involves learning how to
write instructions that do specific tasks

Did you know that problem solving
using computers can help save the
environment?
Going for a Drive

You drive to an
intersection where
you can turn left or
right.

Which turn is
faster to make?
Going for a Drive

If you turn left,
how many lanes do
you have to cross?
Going for a Drive

How about a right
turn?
Not Going Left

Saves a little gas every
turn

UPS uses computer
algorithms to figure
out how to go right 90%
of the time

Saves 3,000,000 gallons
of gas per year
