A teacher Jessie approached the topic of Nutrition in Man by first instructing her students to think about, and question, the necessity of food/nutrition in the human body.

As she wanted students to think about the purpose of the digestive system and the absorption of nutrients, she posed this broad inquiry question to them: "Is faeces a type of excretion?"

From here, students were prompted to think about excretion, which led to vibrant class discussions on KF (Fig. 1 & 2) concerning issues such as what food sources could provide nutrition, what leads to the formation of urine and faeces, etc. They also came up with an array of questions, e.g., "Is faeces edible and is urine drinkable?" Students subsequently went on to do their own research to find out about the components of urine and faeces, and whether they contained any nutrients that could be utilised by the human body.
