ch 1.1
What is a system
A group of parts that work together to perform a desired task
what is a Force
any push or pull. Can be used as an input to a system.
What are some parts(physical and social) of waste management
Physical-landfills, collection trucks and recycling facilities
Social-public education, community engagement and environmental policies
linking personal happiness and satisfaction with the purchase of goods and services
When using a can opener, what is the input force
the force is squeezing the handles and the force transferring to the the cutting mechanism and opening the can.
What is a physical system
A physical system uses physical parts that work together to perform a function.
Subsystems are smaller systems in a system. They help the system perform a task for which it is designed to. Subsystems contain mechanisms that can change one type of force into another, energy into another and motion into another. For example, in a can opener when you squeeze the handles, the mechanism changes the squeeze force into force that cuts the can
Describe some social factors that caused the garbage system to evolve.
As populations grew the concern for the environment increased. We recognize the need for better waste management systems. Many countries like Canada have landfills, recycling programs, public education and incineration and composting.
what is a throw away society
The desire to purchase things that are newer or are the next best thing
This keeps the economy going as sales are much all day long. As new things are made more things are sold
What are the two types of physical systems and 2 examples of each
The two types of physical systems are Human Made and Naturally Made. A Human Made system can be Mechanical(jackhammers-mechanical energy*pneumatic), optical(camera-light energy) or electrical(television-electrical energy) Natural Made systems include solar systems and animal digestive.
example of a industries and related physical systems
communications-computers, scanner,t.v
construction-crane, power saw, backhoe
transportation-gas pump, car, trucks, airplanes
What evolved when populations grew and why
Systems evolve as populations grow because they is a greater concern for implementing better system that will do a better job then current systems. It's all about the next biggest thing.
What are social systems
A group of people or living organisms joining together to perform tasks and establish relationships.
what is input
the force, energy or material energy that you put into a system
what social factors need to be addressed when a conventional school plans to change into a self-directed learning
cultural shifts from passive to active learning, establishing new trust-based student-teacher relationships, building student autonomy and resilience, fostering collaborative peer environments, and managing parental expectations
Why are Aboriginal clans considered human social systems
Because they work together to live successfully. They have strong relationships with themselves and with the land. The have guidance and advice about marriage and ways of life.
what is an output and
systems thinking
The result that you get out of the system an the task that it performs
the consideration of the inputs and outputs and side effects of a system
How have phones changed
Early telephones relied on physical mechanisms with many moving parts. They were big and bulky and had wires. Phones today have no moving parts, are all electronic and they can send messages universal while being mobile.
