Science Test Review

What are systems?

A group of parts that work together to perform a desired task.

What are examples of systems?

Nervous systems, computers, and a car.

What are physical systems?

Systems that rely on a group of physical parts to perform a function.

What are social systems?

A group of people or other organisms joining together to perform a task and establish relationships.

How do systems change when inputs or conditions change?

The system changes because the output depends on the input.

What is systems thinking?

Looking at how all the parts work together, including inputs, outputs, and side effects, and how they affect people and living things.

What do all systems have?

An input, output, and side effect.

What is a natural social system?

Similarities between physical and social systems?

Both have inputs, outputs, and side effects; have a purpose; have components working together.
