How subsystems of the broader educational system are related 
Each subsystem functions to support education in some way
Impact of one component not being present in the school system
How it would impact the system
How the broad educational system is a subsystem of an even larger system 
Example: Students leaving the educational system contribute to other parts of society such as the workforce
How one subsystem affects other subsystems 
Example: Without preschools and elementary schools, schools with older students wouldn't be as effective
Physical Systems 
A group of physical parts that work together to perform a function
Human-made Physical Systems 
Systems that rely on physical parts to perform a task
System
A group of parts working together to perform a specific task
Optical physical systems
Camera
Microscope
Mechanical physical systems
Can opener
Car
Drill
Bicycle
Components of a school system
Principal
Vice principal
Administrative staff
Teachers
Students
Building
Buses
Bus drivers
Custodians
Cafeteria staff
Guidance counselors
School resource officers
Books/supplies
Subsystem
Part of a larger system or connected to a larger system
Function of the user subsystem in GPS
Receives signals from satellites and turns them into useful information
Social Systems 
A group of people or organisms joining together to perform tasks and establish relationships
Function of the space subsystem in GPS
Made up of 24 orbiting satellites transmitting signals to Earth
A bicycle is a system made up of many parts such as wheels, gears, brakes, and frame
Force 
A push or pull on an object that may result in a change to the object's motion or shape
Electrical physical systems 
Circuits
Computers
TV’s
Radio
In physical systems, forces make things move
Rotary 
Revolving motion around a center or axis
Mechanism
The part of a subsystem that changes one type of force, energy, motion, or action into another
Natural Social Systems
Bee colonies
Ant colonies
Wolf pack
Pride of lions
Human-made Social Systems
Musical Orchestra
Health Care
Education
Major subsystems of the global positioning system (GPS)
Space subsystem
Control subsystem
User subsystem
Natural Physical Systems
Solar System
Animal’s Digestive System
Example of a mechanism in a hand mixer
Subsystems of the broader educational system
Preschools
Elementary schools
High schools
Colleges/universities
Superintendent
School board
Function of the control subsystem in GPS
Made up of U.S Air Force monitoring stations
Overlap between systems depends on the function of the system
Natural Physical Systems
Human body contains organ systems such as the digestive system and the circulatory system
Digestive system contains subsystems called organs
When two objects rub and push against each other, they create the force known as friction
Subsystems of the digestive system
Mouth, stomach, intestines
Systems Inputs and Outputs
1. Inputs are all the things that go into a system to make it work
2. Outputs are all of the tasks or services that the system performs
Action-at-a-distance Forces
A ball dropping
Static electricity: your clothes cling to each other as you remove them from the dryer
Magnetism: a magnet is attracted to your refrigerator door
Whenever you push or pull something, you apply force to it
Contact Forces
Rubbing sandpaper on wood
Kicking a football
Teeth in the mouth
Act as a mechanism for cutting and grinding food into smaller pieces
Classifying Forces
Contact Forces
Action-at-a-distance Forces
The main input into a bicycle system is the downward force the rider applies to the bicycle’s pedals
Inputs of a can opener 
Force your hand puts on the handles
Mass 
The amount of matter in an object
