Middle School Life Science
This year, we'll think about things in terms of systems, for example: the Earth as a system; the human body as a system; a cell as a system; computers as systems.
Systems interact with each other, but each can be pictured (modeled) as a discrete thing, that has certain things going on inside, but takes in inputs and produces outputs that affect other systems around it.
We'll start by talking about the Earth as a System.

The Human Body as a System
Inputs and Outputs
- What are the inputs and outputs?
- Where is the boundary?
- Is it an open or closed system?
- How does it interact with other systems?
- What happens to the inputs?
- How are the outputs produced?
- What are the internal systems that process the inputs and produce outputs?
- How do the internal systems interact with each other?
- What things are in equilibrium?
- What type of equilibrium
- How is the equilibrium maintained?
- Are there other internal systems that help regulate the system?

The Earth as a System
Internal systems (sub-systems)
To begin to understand what happens within a system we ask the questions:
- what happens to the inputs when they go in?
- how are the outputs produced?
Which leads to the question:
- What are the internal systems?
- Energy and Matter
- How do the internal systems interact?
