Cellular respiration

About this Illustration of Practice

At St Mary's College, the students undertake an experiment to reinforce their understanding of cellular respiration. As the students undertake the practical lesson measuring the carbon dioxide production from five solutions the classroom teacher who is also the science coordinator circulates among the groups. Asking open and closed questions that unpack their observations, the teacher helps the students establish connections with their prior learning and encourages deeper learning.
