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

4. What is a system?

5. This is a system

9. So, what makes a system a system?

10. 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.

11. What was that again? Two or moreindividual parts that work together to perform a single function And combine to form a whole.

12. Got it?

13. Let us look at a sprinkler system A sprinkler system has many parts. Some parts are above ground. Working sprinklers on grass

14. Some parts are below ground. Underground view of sprinkler system

15. Some parts control what happens. Sprinkler control valves and control box

16. Sometimes parts do not always work right.

17. Some sprinkler systems are simple (have few parts).

18. Some are much more complex.

19. … to water plants. But all sprinkler systems have the same purpose …

20. 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.

21. Let’s look at the parts, the whole, and the purpose

22. Is this a system?

23. Yes! The skateboard has separate parts that combine to form a whole to perform a single function

24. Yes! Has two or more parts that work together to perform a single function.

25. System?

26. Yes! It has ____________ that work together to ____________ And combine to ____________

27. System?

28. Yes! Our bodies have many separate parts making up a whole with a single job—to help us survive!

29. Why is knowing about systems important? Human beings live in a universe made up of systems. Your body is made up of systems Your lives are affected by systems You buy systems You sleep on systems You eat systems Everything you do involves systemsEverything you do involves systems.

30. Are there systems in this room? Classroom Management System Computer System Heating and Cooling System The Pencil Sharpener The Stereo System Wireless Microscope System And lots more With your team list at least four systems that are in this room.

31. 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?

32. ENERGY—in some form. MATTER—some kind of “stuff” so it can do its job INFORMATION

33. Practice with these systems: Find the parts, the INPUT, and THE OUTPUT
