4 th Grade introduction to systems

 How can you identify a system? AA system has lots of parts that work together to serve a purpose. If one part breaks, the system may fail or it might continue working, but not as well as before.

 Handles for lifting  Storage compartment  Pockets/straps  Zipper  Wheels  Extension handle  Luggage tag/ID

 Railroads-a system designed to transport people and heavy goods and products  What are some important parts that define this system?

 Some parts of a system are complex enough to be their own systems. Example: The locomotive that pulls the train is its own system including diesel engines, generators, electric motors, wheels, lights, whistles, and a throttle to adjust speed. Subsystem: a system that is part of a larger system

 We will investigate various systems in plants and animals that function to support survival, growth, behavior and reproduction.  We will explore systems of transport within animals that function to allow animals to receive, process and respond to information.
