SESSION 4.1 Link to known information/ previous activity We have just seen how our body changes the air that we breathe in. Now, let us learn about the parts of the respiratory system that handle the air we breathe. Procedure Ask the learners to summarize what they have learnt so far about breathing in this module. Divide the learners into five groups. Give each group the two slides numbered 1 and 2. Ask all groups to take some Vaseline from the jar and coat Slide 2 with a layer of Vaseline. Place each group’s slides on a window or other place open to air after marking which group it is from. Give each group one chart from the set of five charts prepared for this activity. Tell the groups that they have ten minutes to read and understand the material given in the chart. At the end of ten minutes, each group will need to explain their chart to the whole class. Facilitate this process if any group has difficulties. Figure 12: Model of the respiratory system
While the group is reading, use chalk to draw the diagram shown in Figure 15 in the middle of the class floor or outside on ground. The parts of the diagram should be large enough for the groups to sit in their respective locations. At the end of ten minutes, tell the groups that they will now form the respiratory system. Ask the groups to stand in the circles and semi-circles in the order that they fall in the respiratory system. Once the groups have found the right places, ask them to read and explain to the class the information given in the “Where am I?” and “What am I” sections of their charts. Summarize the information given by the groups using a chart, model or video.
