Changes are now known to have happened both over long periods and virtually instantaneously in both biological and geological terms. In the early grades, certain non-evolutionary changes are used to prepare the student for later, in depth work. Earth and animals change overtime. Some things become extinct. Natural resources can be conserved.
Volcanoes happen, mountains rise, and rocks wear down.
Adaptation takes place. Fossil fuels are explored. Genetic material influences the ability to adapt. Volcanoes and plate tectonics create both quick and gradual change. Patterns of Change provides a framework for creating understanding when changes exist.
