1. LESSON PLAN [circulatory System] ENGLISH SUBJECT MATTER TASK JENY AYU HARDIAH NINGRUM ICP A 1114040162 2. LESSON PLAN School : SMA Class/Semester : XI/1 Subject : Biology Time Allocation : 2x45 minutes Competency Standards : 3. Describe the structure and function of human organs and certain animals, abnormalities / diseases that may occur as well as the implications Basic Competence : 3.2 Explain the relationship between structure, function, and processes as well as disorders / diseases that may occur in the circulatory system I. Indicator 1. Explaining the structure and cardiac function 2. Describe the function of the blood vessel type II. Learning Objectives 1. Student can explain the cardiac structure 2. Student can explain the cardiac pulse 3. Student can describe the blood vessel type 4. Student can differentiate the artery and vena III. Learning Materials 1. Explain the cardiac structure circulatory system 3. The heart and circulation of mammals and birds. (a) The path of blood through the four-chambered heart. (b) The right side of the heart receives deoxygenated blood and pumps it to the lungs; the left side of the heart receives oxygenated blood and pumps it to the body. In this way, the pulmonary and systemic circulations are kept completely separate. RA = right atrium; LA = left atrium; RV = right ventricle; LV = left ventricle. 2. Explain the cardiac pulse The measuring device used is called a sphygmomanometer and measures the blood pressure of the brachial artery found on the inside part of the arm, at the elbow. The systolic pressure is the peak pressure during ventricular systole (contraction of the ventricle). The diastolic pressure is the minimum pressure between heartbeats (repolarization of the ventricles). The blood pressure is written as a ratio of systolic over diastolic pressure, and for a healthy person in his or her twenties, a typical blood pressure is 120/75 (measurement in mm of mercury). 3. Describe the blood vessel type a) Arteries Arteries function in transporting blood away from the heart. The larger arteries contain extra elastic fibers intheir walls, allowing them to recoil each time they receive a volume of blood pumped by the heart. b) Venules and Veins Blood flows from the venules to ever larger veins, and ultimately back to the heart 4. Differentiate the artery and vena 4. IV. Source / Learning Materials Biology Science Book 2A, Henny Riandari, Tiga Serangkai, Solo, 2007, 1622 pages. V.

Phase behavior Time AllocationTeacher Student Pre learning Teacher greeting Teacher absent the students Teacher present the Learning Objectives Students answering greetings Students answered Student record 5 minutes Early Activities 1st Phase: Presents the objectives and motivate students Teachers present all the learning objectives Teachers provide apperception "have you measuring the blood pressure? Students listen to and record the learning objectives Students answer a teacher's question by relating the events that are known from the surrounding environment 10 minutes 2nd Phase presenting information The teacher presents information to students about the cardiac structure Students observe and record important information presented teachers 10 minutes 3rd phase Organize students into learning groups The teacher showed a flash player about cardiac structure Divide students into five groups of heterogeneous Students attention to the video shown by the teacher Students move with his group 25 minutes Main Activity 4th Phase: Guiding study groups and working Teacher gives worksheets to students for discussion and presentation Teachers guide and supervise the discussion Students receive worksheets provided by the teacher Students work on worksheets that teachers shared 35 minutes 5th phase Evaluation Teachers refer students who will make presentations The teacher asks another student to provide corrections or additional explanation Students present the results of their discussion Students are correct or provide additional explanation 15 minutes Closing Activities 6th phase reward Teachers give awards to groups with the best ranking Students who obtained a rating of super team 6.
