Define the concept of systems
Connected parts that work together as a whole
EX. Human body, lake, classroom terrarium
Field trip to nature conservancy
Define cycles
Sequences of changing states of systems
Life cycle of butterfly, water cycle, plant life cycle
Define the scientific concept organization.
Each part of system has a purpose
Human body maintain state of “equilibrium “-balance
What is deposition

Define energy
The capacity of an object to do work/ to cause movement or change
What is velocity
The rate of change in an objects position
Define gravity

What is friction
Resistance in motion when objects rub against each other
Can cause things to slow down or change energy to heat up
What is the earths axis tilt
23,5 degrees
What is weathering
Wind, water, ice cause large rocks to break up into smaller ones
What is erosion
Rock and soil more from one place to another
Human action can accelerate process: deforestation and construction
What is deposition
Layers of sediment are deposited on one another building up land mass ) created formations
.: ocean sandbars
What is weathering
