One Stop Shop For Educators The following instructional plan is part of a GaDOE collection of Unit Frameworks, Performance Tasks, examples of Student Work, and Teacher Commentary. Many more GaDOE approved instructional plans are available by using the Search Standards feature located on GeorgiaStandards.Org. Georgia Performance Standards Framework for Life Science- 7th Grade Unit: Heredity ~ Genetics Sternberg Task Inheritance Patterns Subject Area: Life Science Grade: 7th Standards (Content and Characteristics): S7L3. Students will recognize how biological traits are passed on to successive generations. a. Explain the role of genes and chromosomes in the process of inheriting a specific trait. b. Compare and contrast sexual and asexual reproduction in organisms (bacteria, protists, fungi, plants, & animals). S7CS6. Students will communicate scientific ideas and activities clearly. a. Organize scientific information using appropriate simple tables, charts, and graphs, and identify relationships they reveal. Enduring Understanding: Many traits of an organism are inherited from its biological parents. Genes and chromosomes determine the expressions of inherited traits. Essential Question(s): How can I predict what traits will be passed from one generation to another? How are genes and chromosomes important in determining heredity traits? Pre-Assessment: Teacher will make a construction paper box. http://familycrafts.about.com/cs/coloringpages/l/blboxtemplate.htm The teacher will write a question about genetics on each side of the cube. Students will work in groups rolling the dice and answering the questions.

Student role? ANALYTICAL Students will analyze inheritance patterns within a pedigree chart. (i.e. The European Royal Family) PRACTICAL Students will make and analyze an illustrated pedigree chart of a specific physical trait using photographs of their family members. (Possibly using pictures of teachers family members if student’s living arrangement limits his/her ability to obtain accurate photographs) *Teachers would need to be sensitive to student’s individual living arrangements.

Teacher Role: Monitor student work Provide individual instruction as needed. Student Role: Students will write and illustrate a picture book. The book should include an explanation of how traits are passed from one generation to another. The main characters of the story are Mama Gene and Daddy Gene. Students will need to be sure they provide a clear description of the role these two main characters and explain and how their “marriage” creates a chromosome.

List step-by-step directions for task, provide checklists and checkpoints. Instructional Tasks Accommodations for Provide written instructions on the format of the pedigree charts. Allow student to work with an English speaking student. ELL Students Extended time will be given to student to complete assignment. Instructional Tasks Accommodations for Students with Disabilities Instructional Tasks Accommodations for Gifted Students Allow students to use different colored markers to help with organization. Provide guided questions to aid students in evaluation/analysis of pedigree chart. Provide step-by-step checklist to aid in organization and completion of task. Students can research and present the use of karyotypes in genetics. Students can complete various karyotype activities online. http://learn.genetics.utah.edu/units/disorders/karyotype/karyotype.cfm http://learn.genetics.utah.edu/units/disorders/karyotype/ http://www.biology.arizona.edu/human_bio/activities/karyotyping/karyotyping.html Georgia Department of Education Kathy Cox, State Superintendent of Schools Life Science 7th Grade Genetics/Heredity August 8, 2007 Page 4 of 4 Copyright 2007 © All Rights Reserved
