Los and Ass Teaching & Learning Activities Details of assessment LO 1: SCIENTIFIC Activity 1 Assessment Task INVESTIGATIONS Learners discuss in groups how they think blood is transported in human Research Project body and identifies the different parts of the blood circulatory system and Learners visit nearby Health AS: Plans investigations: the function of the heart.

8 Centres to do a research on the AS: Conducts investigation Teacher asks learners to listen to the next persons heart beat, count for a minute and takes the average value of responses from different risk factors of Cholesterol, and collects data learners. High Blood Pressure, AS: Evaluates data and The teacher uses an analogy (Transport system: taxis, buses, etc.) to Hypertension, Asthma, and communicates findings explain the circulatory systems in human beings. other Heart related diseases. LO2: CONSTRUCTING Teacher explains the composition and function of blood. Write a written report based on SCIENCE KNOWLEDGE: the information collected under Activity 2: AS: Recalls meaningful the heading risk factors, With the help of charts/ models the teacher explains different parts of the information:: circulatory system which are heart and blood vessels.

9 Causes, preventive measures. L O 3: SCIENCE, SOCIETY Learners identify the parts of the circulatory system. Make a drawing of the circulatory system. AND THE ENVIRONMENT. Teacher engages the learners in the discussion of the structure and AS: Understands science and functions of the heart and different blood vessels. Make a model of the heart. technology in the context of history and indigenous Activity 3: The learners do research on the risk factors of heart related knowledge. diseases and have to present it to the class. Activity 4: Discuss health risks and heart diseases and the relationship to have a healthy diet.

10 [The special arteries that bring blood and oxygen to the heart muscle can clog up. They can clog up with clumps of fat called plaque. Blood cannot flow through clogged arteries. Clogged arteries can cause heart attacks. Exercise is one way to keep your heart healthy. Eating fruits, vegetables, and low-fat meats is another way to keep your heart healthy. You should have regular physical checkups. The main way to keep your heart healthy, however, is not to smoke. Heart Related Diseases are normally found from people who sometimes fail to take precautionary measures and they can prove to be fatal at times].
