Life Sciences: List of Indicators

Benchmark A: [3-5] Heredity
Differentiate between the life cycles of different plants and animals.

Grade 3

Grade 4

Grade 5

Grade-Level Indicators

Heredity

1. Compare the life cycles of different animals including birth to adulthood, reproduction and death (e.g., egg-tadpole-frog, egg-caterpillar-chrysalis-butterfly). 

Heredity

1. Compare the life cycles of different plants including germination, maturity, reproduction and death.

5. Describe how organisms interact with one another in various ways (e.g., many plants depend on animals for carrying pollen or dispersing seeds).

 

No indicators present for this benchmark.


Benchmark B: [3-5] Diversity and Interdependence of Life
Analyze plant and animal structures and functions needed for survival and describe the flow of energy through a system that all organisms use to survive.

Grade 3

Grade 4

Grade 5

Grade-Level Indicators

Diversity and Interdependence of Life

2. Relate animal structures to their specific survival functions (e.g., obtaining food, escaping or hiding from enemies).

3. Classify animals according to their characteristics (e.g., body coverings and body structure).

Diversity and Interdependence of Life 

2. Relate plant structures to their specific functions (e.g., growth, survival and reproduction).

3. Classify common plants according to their characteristics (e.g., tree leaves, flowers, seeds, roots and stems).

Diversity and Interdependence of Life 

1. Describe the role of producers in the transfer of energy entering ecosystems as sunlight to chemical energy through photosynthesis.

2. Explain how almost all kinds of animals' food can be traced back to plants.

3. Trace the organization of simple food chains and food webs (e.g., producers, herbivores, carnivores, omnivores and decomposers).


Benchmark C: [3-5] Diversity and Interdependence of Life
Compare changes in an organism's ecosystem/habitat that affect its survival.

Grade 3

Grade 4

Grade 5

Grade-Level Indicators

Diversity and Interdependence of Life 

4. Use examples to explain that extinct organisms may resemble organisms that are alive today.

5. Observe and explore how fossils provide evidence about animals that lived long ago and the nature of the environment at that time.

6. Describe how changes in an organism's habitat are sometimes beneficial and sometimes harmful.

Diversity and Interdependence of Life 

4. Observe and explore that fossils provide evidence about plants that lived long ago and the nature of the environment at that time.

Diversity and Interdependence of Life 

4. Summarize that organisms can survive only in ecosystems in which their needs can be met (e.g., food, water, shelter, air, carrying capacity and waste disposal). The world has
different ecosystems and distinct ecosystems support the lives of different types of organisms.

5. Support how an organism's patterns of behavior are related to the nature of that organism's ecosystem, including the kinds and numbers of other organisms present, the availability of food and resources, and the
changing physical characteristics of the ecosystem.

6. Analyze how all organisms, including humans, cause changes in their ecosystems and how these changes can be beneficial, neutral or detrimental (e.g., beaver ponds, earthworm burrows, grasshoppers eating plants, people
planting and cutting trees and people introducing a new species).
