An object can change in various ways, such as in size, weight, color, or temperature.
Learning Goal 3b
Small changes can sometimes be detected by comparing counts or measurements at different times.
Learning Goal 4
Some things change so slowly or so quickly that the changes are hard to notice while they are taking place.
For Grades: 3-5
Learning Goal 1
Some features of things may stay the same even when other features change.
Learning Goal 2a
Things change in steady, repetitive, or erratic ways—or sometimes in more than one way at the same time.
Learning Goal 2b
Often the best way to tell which kinds of change are happening is to make a table or graph of measurements.
For Grades: 6-8
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 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.
