|
| |
|
|
|
|
Key Idea

|
|
|
|
Key Idea
|
Many of the phenomena that we observe on Earth involve interactions among components of air, water, and land.
|
| |
PI |

|
|
| |
PI |
Students describe volcano and earthquake patterns, the rock cycle, and weather and climate changes.
|
|
| |
|
|
|
|
Key Idea
|
Matter is made up of particles whose properties determine the observable characteristics of matter and its reactivity.
|
| |
PI |
Students observe and describe properties of materials, such as density, conductivity, and solubility.
|
|
| |
PI |
Students distinguish between chemical and physical changes.
|
|
| |
PI |
Students develop their own mental models to explain common chemical reactions and changes in states of matter.
|
|
| |
|
|
|
|
Key Idea
|
The Earth and celestial phenomena can be described by principles of relative motion and perspective.
|
| |
PI |
Students explain daily, monthly, and seasonal changes on earth.
|
|
| |
|
|
|
|
Key Idea
|
Human decisions and activities have had a profound impact on the physical and living environment.
|
| |
PI |
Students describe how living things, including humans, depend upon the living and nonliving environment for their survival.
|
|
| |
PI |
Students describe the effects of environmental changes on humans and other populations.
|
|
| |
|
|
|
|
Key Idea
|
Individual organisms and species change over time.
|
| |
PI |
Students describe sources of variation in organisms and their structures and relate the variations to survival.
|
|
| |
PI |
Students describe factors responsible for competition within species and the significance of that competition.
|
|
| |
|
|
|
|
Key Idea
|
Living things are both similar to and different from each other and nonliving things.
|
| |
PI |
Students compare and contrast the parts of plants, animals, and one-celled organisms.
|
|
| |
PI |
Students explain the functioning of the major human organ systems and their interactions.
|
|
| |
|
|
|
|
Key Idea
|
Organisms inherit genetic information in a variety of ways that result in continuity of structure and function between parents and offspring.
|
| |
PI |
Students describe sexual and asexual mechanisms for passing genetic materials from generation to generation.
|
|
| |
PI |
Students describe simple mechanisms related to the inheritance of some physical traits in offspring.
|
|
| |
|
|
|
|
Key Idea
|
Organisms maintain a dynamic equilibrium that sustains life.
|
| |
PI |
Students compare the way a variety of living specimens carry out basic life functions and maintain dynamic equilibrium.
|
|
| |
PI |
Students describe the importance of major nutrients, vitamins, and minerals in maintaining health and promoting growth and explain the need for a constant input of energy for living organisms.
|
|
| |
|
|
|
|
Key Idea
|
Plants and animals depend on each other and their physical environment.
|
| |
PI |
Students describe the flow of energy and matter through food chains and food webs.
|
|
| |
PI |
Students provide evidence that green plants make food and explain the significance of this process to other organisms.
|
|
| |
|
|
|
|
Key Idea
|
The continuity of life is sustained through reproduction and development.
|
| |
PI |
Students observe and describe the variations in reproductive patterns of organisms, including asexual and sexual reproduction.
|
|
| |
PI |
Students explain the role of sperm and egg cells in sexual reproduction.
