1. Explain that there are identifiable stages in the life cycles (growth, reproduction, and death) of plants and animals.
|
a. Identify and draw pictures that show what an animal (egg to frog) and a plant (seed to tree) looks like at each stage of its life cycle.
|
a. Examine a variety of populations of plants and animals (including humans), to identify ways that individual members of that population are different from one another.
|
a. Investigate and describe that seeds change and grow into plants.
|
b. Describe and compare the changes that occur in the life cycle of two different animals, such as a frog and a puppy and two different plants, such as a rosebush and a maple tree.

b. Make a list of possible advantages and disadvantages of differences of individuals in a population of organisms.
|
b. Compare and describe the changes that occur in humans during their life cycle (birth, newborn, child, adolescent, adult, elder).
|
c. Identify and describe the changes that occur in humans as they develop.

|
|
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.
|
|
|
2. Recognize that all living things have offspring, usually with two parents involved.

b. Identify similarities and differences among the offspring and between the offspring and each parent.
|
|
|
