Introduction
Aim Students will learn the function of bloodvessels
and blood cells in the circulatory system
Rationale Through media, students are aware
of the race between the private companies and the government/public research
group for mapping the genes. Students may not understand just what
mapping involves, however, they are familiar with the term,genes.
With news of the race between the two, student interest has been
piqued.
Goals and Objectives This module teaches students
how to use a genetic pedigree.
At he conclusion of this lesson, students will:
-
be able to describe the chemical and structural properties
of DNA, genes and chromosomes and their roles in determing hereditary traits
-
be able to demonstrate how many traits have components
that are inherited and other components that result from interaction with
the enviornment
-
demonstrate how probability relates to genetics
-
to participate in a genetic counseling situation to help to determine if
offspring will be a carrier of a trait, or if the offspring display the
trait.
Audience This lesson is for seventh and eighth grade
students
-
Prerequisites Learners
should be familar with:
-
Mendel's experiments with pea plant characteristics.
-
Cell cycles of mitosis and meiosis
Subject-Matter Alleles of genes to determine
dominant or recessive traits.
Instructional Plan
Materials Textbooks, chalkboard,paper,pencil,
websites
Assessment and Evaluation Students will
engage in role play situations as genetic counselors for persons who want
information on the probability of being dominant for certain familial traits.
