Genetics block 3

Unit: Genetics – Block 3 Introduction Lesson topic: Punnett Squares Length of Lesson: 1.5 hr lab VA Standards of Learning: ° BIO 1.i and j– Students will plan and conduct investigations in which appropriate technology is used for gathering and analyzing data and communicating results; utilizing scientific literature ° BIO 6.d – Students will investigate and understand how to predict the inheritance of traits based on the Mendelian laws of heredity Cognitive Objectives for All Students: SWBAT predict possible gametes in a dihybrid cross, given parental genotypes SWBAT use a Punnett square to show all possible combinations of gametes and the likelihood that particular combinations will occur in monohybrid crosses SWBAT demonstrate knowledge by completing journal SWBAT demonstrate prior knowledge by Punnett Square practice problem SWBAT participate – at least by listening – in class discussion SWBAT participate in small group Punnett Square lab SWBAT rate themselves on their understanding by discussing with group mates the Punnett Square lab Cognitive Objectives for Some Students: SWBAT complete all crosses SWBAT participate – by contribution – in class discussion SWBAT assist other students in lab work Materials and Advanced Preparation Miller and Levine’s Biology textbook CITATION Mil08 1033 (Miller & Joseph, 2008): Chapter 11.1 – 11.3 Book the computer lab Have computers set to Carter’s Genetics Practice Problems website: http://biology.clc.uc.edu/courses/bio105/geneprob.htm Teaching and Learning Sequence Introduction/Anticipatory Set ° Begin with an oral overview of what was taught the day before, answering questions as needed (Reflection – previous day) ° Have each group do a Punnett Square and then discuss it (Preparation) Lesson Development ° Working in groups (of students with different abilities), have students work through all 12 problems in their journal ° Each group must show me their answers before moving on to the next problem (Assistance) Closure ° By checking journals, make sure each student feels confident with their ability to complete Punnett Squares (they will only be tested on monohybrid and dihybrid crosses) (Reflection) ° Assign chapter 12.4 and 12.5 to read for homework in preparation of the next day’s lesson; mutations lab Homework Assign chapter 12.4 and 12.5 to read for homework in preparation of the next day’s lesson; mutations lab Assessment Formative – Going around the room making sure each group is on task and working together Summative – After completion of the lab, students will be evaluated on their journals References Carter, J.
