A system may stay the same because nothing is influencing it or the influences on it are balanced.
Learning Goal 3
Many systems contain feedback mechanisms that serve to keep changes within certain limits.
Learning Goal 4
Symbolic equations can be used to summarize how the quantity of something changes over time or in response to other changes.
Learning Goal 6
Cycles, such as the seasons or body temperature, can be described by what their cycle length or frequency is, what their highest and lowest values are, and when these values occur. Different cycles range from many years down to a fraction of a second.
Learning Goal 7
Cyclic patterns evident in past events can be used to make predictions about future events. However, these predictions may not always match what actually happens.
Learning Goal 8
The way some systems behave is so erratic that patterns of change are not apparent.
Learning Goal 9
Small differences in how things start out can sometimes produce large differences in how they end up. Some events are so sensitive to small differences in initial conditions that their outcomes cannot be predicted.
Learning Goal 10
Trends based on what has happened in the past can be used to make predictions about what things will be like in the future. However, these predictions may not always match what actually happens.
Learning Goal 11
The amount of something in a system may stay the same because nothing is entering or leaving the system or because something is being added to the system at the same rate as it is leaving the system.
