Human Biology

1. Following fertilization, cell division produces a small cluster of cells that then differentiate by appearance and function to form the basic tissues of an embryo. During the first three months of pregnancy, organs begin to form. During the second three months, all organs and body features develop. During the last three months, the organs and features mature enough to function well after birth. Patterns of human development are similar to those of other vertebrates. (AKSci - A.10)

Examples of What Students Should Be Able to Do:

•  Observe, describe, and measure changes that occur in an organism (e.g., bean plant, butterfly, frog, chicken) as it develops from a seed or fertilized egg into an adult and compare to a human.
