Teach Resource for Instructional Planning


Grade 7, Science Std #: 10.1 Identify the mechanisms through which DNA can be mutated.

Lesson Plans: Reaching into Your Genes The students will interact with a video to explore the basis for the science of chromosomes. They then perform a chromosomal analysis called a karyotype and learn how seemingly minute errors in chromosomes can lead to devastating illnesses. Monstrous Mutations Students will understand, recognize and observe mutations. DNA & Genetics Students complete a teacher-made scavenger hunt as an introduction to DNA and genetics, then watch a short video and use their science books to learn more about the topic. Students work in pairs to investigate DNA, genetics, and cloning through internet research and compile their information in the form of their own internet scavenger hunt. How Cells Duplicate and Why Cells are the basic unit of function and structure in living things. After students have learned cell parts and organization, they are introduced to cell division. Understanding the role of deoxyribonucleic acid (DNA), and how and why it must replicate, is essential to comprehending how our genetic patterns are transmitted to new cells. Constructing a three-dimensional model of the DNA molecule enhances the students' discernment. Breaking the Code The students will know that DNA is unzipped and paired with mRNA, decoded by tRNA, which is read and translated into chains of amino acids, which make up proteins. Drosphila: Introduction and Genetics Introduction to Drosophila including life cycle, sexing, and identifying mutations. Creating Chromosomes This visual exercise helps students understand the concepts of homologous chromosomes, non-homologous chromosomes, crossing over, and deletion. Genetic Diseases Related to Sex Chromosomes Students will develop a Power Point presentation on a genetic disease.

Resources: How do Mutations Occur? Excellent resource with reference information and interactive activities Mutate a DNA Sentence! Students practice decoding DNA. How do Mutations Cause Genetic Disorders? Clear up misconceptions related to this topic Teacher's Domain The story of mutation with a video Nation Master An encyclopedia description of mutation
