Model
Types of models
Energy Transformations
3D smaller items, computer simulations, diagrams, pictures.
When matter or energy moves inside of a system
When energy moves from one system (object) to another system (object)
For tracking energy and matter flows so that we can better understand the concept
To help us understand systems better by allowing us to study it, perform experiments, etc on a smaller version of the system
Predator population
Prey population
Energy can change from one type of energy to another type of energy when it interacts with a system
When matter cannot enter or leave a system, but energy can enter/leave
Autotroph population
What a system is designed for...it's job/role
When matter can enter and leave a system.
The system or object under study. Not a representation
Representation of the actual system
Systems effect other systems. Objects and energy will leave one system and enter another system.
