7th Grade Science Unit 4: Genetics and Health Lafayette Parish School System 2013-2014 LPSS Science Teacher Leader Cadre Annette Chapman – Paul Breaux André Deshotel – Judice Nathan Griffin – LJ Alleman Nanette Meaux – Milton Bridget Trahan – LPSS Science Lead Teacher Lafayette Parish School System 2013-2014 Curriculum Map Grade: 7th Science: Unit 4: Genetics and Health Time Frame: March 17 – May 23 (34 Days) Unit Description and Student Understandings: This unit focuses on the basic concepts of genetics. Major topics include sexual and asexual reproduction, mitosis and meiosis, genes and chromosomes, and Mendel’s laws. The use of Punnett squares to predict traits will be presented in the unit. Students will compare and contrast the processes or concepts of sexual and asexual reproduction, and mitosis and meiosis. Differentiate between the two types of reproduction and forms of cell division. Students will correctly complete Punnett squares to predict phenotypic and genotypic probability ratios in the offspring of genetic crosses involving dominate and recessive traits. Identify and describe uses of fertilization and selective breeding and genetic engineering. This unit will focus on how human life can be influenced by external factors and genetics. It will discuss the effects lifestyle choices such as the use of tobacco and drugs can have on the body. Common communicable and noncommunicable diseases and the methods by which they are transmitted, treated, and prevented are among topics covered. Good health is the result of heredity and care and respect for the human body. It is also important that students be able to describe how diseases are contracted and to select behaviors that prevent the spread of disease. In the study of science, students should be able to explain germ theory. Students will participate in a historical research project of how society has acted to prevent or control certain diseases with particular attention given to science and its role in finding cures or preventive measures. Students will also address the issue of nutrition by creating charts that will allow them to evaluate the nutritional knowledge of teens. Guiding Questions: 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. Can students describe sexual and asexual reproduction and cite examples of each? Can students articulate the major difference between mitosis and meiosis and describe the phases of each process? Can students describe how genetic information is passed from one generation to the next? Can students identify a genetic trait and explain the link via Punnett squares? Can students explain and identify how and when a change in the DNA molecule can cause a disorder? Can students list the physical and emotional effects of poor nutrition, smoking, drug use, and the lack of exercise? Can students describe appropriate lifestyle changes that can prevent serious illness? Can students describe diseases that are influenced by genetic as well as external factors? Can students differentiate between communicable and noncommunicable diseases? Can students describe the methods by which communicable diseases are transmitted, treated and prevented? Key Concepts: Identify statements that describe sexual and asexual reproduction Compare sexual and asexual reproduction Compare mitosis and meiosis and differentiate between the cell divisions in each process Contrast meiosis and mitosis and recognize the function of each type of cell division Explain why chromosomes in body cells exist in pairs Differentiate among the structure and roles of DNA, genes, and chromosomes Explain the relationship of genes to chromosomes Explain the relationship of genotypes and phenotypes Differentiate between genotype and phenotype and be able to predict either for simple monohybrid crosses using a Punnett square Use a Punnett square to determine offspring in simple monohybrid crosses Identify dominant, recessive, and incomplete dominant traits from a given scenario Identify examples of selective breeding 7th Grade Science 2013-2014 Lafayette Parish School System 2013-2014 Curriculum Map Grade: 7th Science: Unit 4: Genetics and Health Time Frame: March 17 – May 23 (34 Days) Recognize genetic errors caused by changes in chromosomes Recognize major communicable, noncommunicable, and genetic diseases or disorders and identify causes, preventative measures, symptoms, and treatments Describe how external factors and genetics influences quality and length of human life Explain how communicable and noncommunicable diseases are transmitted, treated and prevented Vocabulary List: asexual reproduction, sexual reproduction Anaphase, Cell Cycle, Chromatid, Chromatin, Chromosome, Cytokinesis, daughter cell, gamete, heredity, interphase, metaphase, prophase, replication, telophase Adenine, Guanine, Thymine, Cytosine, allele, amino acid, inheritance DNA, gene, genetics, genotype, phenotype, heredity, inheritance, protein, RNA, lipids Punnett Square Heterozygous, Homozygous, dominant, recessive genetic disorder, mutation GLEs CCSS Literacy Standards NGSS Practices Instructional Strategies Differentiation (Enrichment/Remediation Strategies) Be sure to include an iLEAP review/Blitz before testing March 31 – April 4 It would be a good idea to administer the 7th Grade Post Test before the Spring Intercession during the week of April 14-17.
