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:

    • define terms dominant, recessive, heterozygous, homozygous, genotype, and phenotype
    • explain how Mendel derived ratios from his observations
    • calculate ratios, by using Punnett Squares
    • explain and complete monohybrid crosses
    • 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:

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