MINDS - ONOPTION 1: MENDING A BROKEN HEART
Students are given an article to read called "Mending a broken heart". In pairs of two they take turns talking about the article. After they have had a chance to discuss the article with their partner, a class discussion is initiated around the functions of the heart and why heart regeneration can save human lives. OPTION 2: BREATHING AND HOLDING YOUR BREATH This activity gives students a better understanding of why we breath and cells need oxygen. It leads into a discussion as to why blood carries oxygen to different parts of the body and carbondioxide out of the body. Then students carry out an experiement to see how changing levels of oxygen can modify how long they hold their breath. |
PEDAGOGYThe purpose of the minds on is to get students thinking about the heart and it's function. Both minds on a good way to introduce the heart and get students thinking about what role the heart plays in the circulatory system. Both activities are a great way to lead into both the monitoring of the circulator system section and diseases of the circulatory system.
BACKWARD DESIGN MODEL: It is a good time to remind students to start thinking about their presentations. Reminding them that all organs of the circulatory system work together and understanding the form and function of the heart will help them understand why things go wrong. |
LESSON ON STRUCTURE OF HUMAN HEART & FUNCTION |
Starting with a video gives not only aids visual learners but most learners benefit from seeing structure and function of a system. Showing a video before the lesson and then re-visiting the video after the lesson has been completed re-enforces concepts.

OPTION #1: Lesson PPT on Structure and Function of the heart
OPTION #2: HOME GROUP & EXPERT GROUP Divide the class into groups of 4. Each group will be given a poster size outline of the heart. One in their "home groups", each student in their group will be assigned numbers 1-4. Each number will represent a section of the heart: 1. LEFT VENTRICLE 2. RIGHT VENTRICLE 3. LEFT ATRIUM 4. RIGHT ATRIUM In their "expert groups", students will discuss the structure and function of their part, using the textbook as a resource. Students will be given about 30 minutes to finish this part of the activity. They will then return to their home groups and will teach the other students in their group about their part of the heart. They will then have to complete the heart diagram by labelling and explaining the functions of the heart. The sheets can then be put up in the class for students to see and take notes from. |
Whether you use the SMARTBOARD, Powerpoint or Prezi, doing a lesson on the structure and function, this type of technology seems to be the most preferred or most convenient way of teaching lessons. Visuals can be used throughout the lessons. SMART EXCHANGE offers a wide variety of lessons, simulations and activities that are interactive and will help engage students.
If you find that your class is not engaged and that ppt type teaching is not the best means to teach them, an activity type learning lesson, such as the home group - expert group allows them to teach their peers, which is an excellent way to learn. This activity may not work with all classrooms and may require teachers to strategically place students in specific groups. |
CONSOLIDATING
DIAGRAM OF THE HEART: COLOUR AND LABEL
Students are given a blank diagram of the heart. They have to label and colour the diagram. They can use their textbooks or any approved resources on the internet to complete this task. Provide students with colour pencils. |
This section of the unit is heavy in terms of content and terminology. Giving students an easy activity to wind down and reconfirm their knowledge of the material is helpful in ensuring students can check their learning.

BLOOD FLOW THROUGH THE HEART SONG
|
Songs are a great way to reinforce concepts. Specially when they are tunes to the latest songs that students can relate, for e.g. this song is sung to a popular Bruno Mars song. |
