Lesson Plan #:AELP-GET0004

Fundamentals of Genetics

An Educator's Reference Desk Lesson Plan

Submitted by: Jodi  Gardner
Email: bgst7+@pitt.edu

Date: January 28, 2000

Grade Level(s):  9, 10

Subject(s):

  • Science/Genetics
Description: Students engage in activities on Mendalian genetics using an interactive Web-based tutorial.

Goals:  Students will be able to define, calculate, and explain various aspects of Mendalian genetics.

Objective(s):

 Students will be able to:

  1. define terms dominant, recessive, heterozygous, homozygous, genotype, and phenotype
  2. explain how Mendel derived ratios from his observations
  3. calculate ratios, by using Punnett Squares
  4. explain and complete monohybrid crosses
  5. effectively manipulate the interactive website
Materials:
  •  24- Computer Lab
  •  back-up activity in case system goes down
    • Procedure:

    Clerical/Administrative Tasks:

    Take role
    Copy back-up activity

    Introduction:

    Motivation- Is it possible for two people with brown eyes to have a child with blue eyes.

    Demonstration- Overhead of Punnett Square explaining how it is possible.

    Development:

    Directions- explain concepts using website given below as visual aid.
    Go to interactive website The Biology Project - Mendelian Genetics
    Work on problems and tutorials on monohybrid crosses, individually.
    Monitor activity: keep students on task.

    Closure:

    Any questions about lesson?
    Discuss other attributes besides eye color that are dominant/recessive in humans.
    Match students in twos; use Punnett squares to find if their offspring would have a certain attribute.

    Assessment:

    Students will:

    1. define terms dominant, recessive, heterozygous, homozygous, genotype, and phenotype accurately
    2. calculate ratios, by using Punnett Squares accurately
    3. explain and complete monohybrid crosses
    4. effectively manipulate the interactive website
