Lesson objectives

This exemplar lesson is very different to the others as the application is not an experiment or instrument. Instead, it is a tool that allows students to explore an anatomically correct human heart and investigate many of its functions and properties.

By the end of the lesson, you will be able to:

• Describe the structure of the mammalian heart (Biology 4.3.2 and Integrated Science 3.3.1)
• Draw and Label key structural features on diagrams of the heart (Biology 4.3.2 and Integrated Science 3.3.1)
• Explain the function of the heart and how blood flows through the heart (Biology 4.3.2 and Integrated Science 3.3.1)
• Explain the mechanism of heart excitation and contraction (Biology 4.3.3 and Integrated Science 3.1.3)
• Interpret activity traces of the cardiac cycle (Biology 4.3.3 and Integrated Science 3.1.3)
• Calculate the heart rate of a person (Practical and Experimental Skills)
• Plan, design and carry out an experiment testing the effects of exercise on a person’s heart rate (Practical and Experimental Skills)

The following practical and experimental skills will also be developed:

• Observation
• Manipulation
• Drawing
• Interpretation
• Planning and designing of experiments
• Measuring
• Recording
• Reporting
• Conduct in laboratory

Please note that any terms shown in bold, are defined in the Glossary, at the end of this Lesson Plan.
