|
Standard 3.0 Life Science: The students will use scientific skills and processes to explain the dynamic nature of living things, their interactions, and the results from the interactions that occur over time.
|
|
A. Diversity of Life
|
|
B. Cells
|
|
C. Genetics
|
1. Explain that there are identifiable stages in the life cycles (growth, reproduction, and death) of plants and animals.
|
a. Investigate and describe that seeds change and grow into plants.
|
b. Compare and describe the changes that occur in humans during their life cycle (birth, newborn, child, adolescent, adult, elder).
|
c. Given pictures of stages in the life cycle of a plant or an animal, determine the sequence of the stages in the life cycle.
|
d. Provide examples, using observations and information from readings that life cycles differ from species to species.
|
|
D. Evolution
|
1. Observe and describe examples of variation (differences) among individuals of one kind within a population.
|
a. Observe and describe individuals in familiar animal populations, such as cats or dogs, to identify how they look alike and how they are different.
|
b. Examine pictures of organisms that lived long ago, such as dinosaurs, and describe how they resemble organisms that are alive today.
|
c. Recognize that some kinds of organisms have completely disappeared.
|
|
E. Flow of Matter and Energy
|
|
F. Ecology
|
1. Explain that organisms can grow and survive in many very different habitats.
|
a. Investigate a variety of familiar and unfamiliar habitats and describe how animals and plants found there maintain their lives and survive to reproduce.
|
b. Explain that organisms live in habitats that provide their basic needs.
|
c. Explain that animals and plants sometimes cause changes in their environments.
