Today’s Purpose
1. What is a system?
2.Can students identify systems around them?
Our purpose today is to answer the questions:

This is a system
This is a system
This is a system
This is a system
So, what makes a system a system?
What is our definition of a system?
• Two or more individual parts that work together to perform a single function (job) and combine to form a whole.
What was that again?
• Two or more individual parts

And combine to form a whole.
Got it?
Let us look at a sprinkler system
A sprinkler system has many parts.
Some parts are above ground.
Working sprinklers on grass
Some parts are below ground.
Underground view of sprinkler system
Some parts control what happens.
Sprinkler control valves and control box
Sometimes parts do not always work right.
Some sprinkler systems are simple (have few parts).
Some are much more complex.
… to water plants.
But all sprinkler systems have the same purpose…
Remember our definition of a system?
• Two or more individual parts that work together to perform a single function and combine to form a whole.
Let’s look at the parts, the whole, and the purpose
Is this a system?
Yes!
The skateboard has separate parts that combine to form a whole to perform a single function
Yes!
Has two or more parts that work together to perform a single function.
System?
Yes!

Are there systems in this room?
• Classroom Management System

With your team list at least four systems that are in this room.
• Every system has an INPUT and OUTPUT. Its OUTPUT is the function (job) that it does or the result of its job. What is its INPUT?
• ENERGY—in some form.
• MATTER—some kind of “stuff” so it can do its job
• INFORMATION
Practice with these systems:
• Find the parts, the INPUT, and THE OUTPUT
• Find the parts, the INPUT, and THE OUTPUT
• Find the parts, the INPUT, and THE OUTPUT
• Find the parts, the INPUT, and THE OUTPUT
