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 • The wolf will eat the sheep • The sheep will eat the carrot BUT if left alone,

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 • COMPUTER SCIENCE IS SO MUCH MORE!
Let’s program the robot to make a sandwich! The robot can only do exactly what you tell him to do!
….another CS-Related Topic 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
