Primary

Change and evolution Concepts

1. Change can be fast or slow. An organism's form is related to its environment.
2. Modern organisms may resemble extinct organisms.
3. Objects and organisms can be changed to function for better or worse.

Equilibrium Concepts

1. Changes can balance.

Intermediate

Change and evolution Concepts

1. Changes may not be noticed on a scale of a human's life time.
2. However, these changes become large as the number of lifetimes become large.

Equilibrium Concepts

1. Objects and events move toward equilibrium (sugar in water disperses throughout the liquid, pendulum swings until it stops at the lowest point, water flows…

Middle School

Change and evolution Concepts

1. Present conditions such as the salt in the oceans, continental drift, erosion of land forms, changes in organisms... can be explained as gradual and sporadic.
2. Evolution is the idea of the present arising from materials and forms of the past.
3. Sometimes a series of changes occurs so slowly or so rapidly that it is difficult to document the evolution.
4. In evolving systems, change can be gradual, steady, repetitive, irregular, or in more than one way at the same time.
