LESSON PLAN Form: 5 SAINS 1 Date: 19th June 2015 Level: Intermediate Time: 9.30 a.m. -10.00 a.m. Topic: 5.0 Inheritances Subtopic: 5.2 Inheritance traits of human Objectives: Understanding inheritance Learning outcomes: At the end of this lesson, students should be able to: State the blood groups in the ABO system and Rhesus factor in humans. Explain the inheritance of ABO blood group in humans. Moral values: 1. One should acknowledge their type of blood to avoid diseases for the next generation. 2. People can help their siblings through blood test for donation. 3. People will acknowledge their rhesus factor to avoid death during blood transfusion or pregnancies. Educational Emphasis: Science Process Skills: observing, classifying, communicating, defining operationally. Critical Thinking Skills: analysing, attributing, comparing and contrasting. Creative Thinking Skills: generating ideas, relating, making generalisations, visualising, making analogies. Instructional Aids: Whiteboard marker, A4 paper with tasks, handouts.

Follow-up activity: Teacher asks students to read about autosomes and sex chromosomes, different human karyotypes, sex determination in offspring, sex-linked inheritance and hereditary disease. Teacher will ask in the next teaching. Self-evaluation: Supervisors’ Comments:
