The lesson begins with an introduction into what happens to your food during the process of digestion, students are shown a diagram which demonstrates how large, insoluble food molecules are broken down into small, soluble ones. This follows into the definition and role of the human digestive system, students now need to discuss their ideas of the names of organs present in the digestive system.
After a short class discussion, students will now complete a ‘Memory Test’ task. Students will need be shown a diagram of the human digestive system with organs labelled. They will have a few minutes to memorise the names of the organs of the digestive system, the labels will be taken away and then students need to try to remember as many of them as possible, by labelling their own digestive system worksheet. This task can be self-assessed once it is competed.
Next, students will be given an information sheet in pairs. Students will need to read the information sheet and using this write a description of the roles of a set of organs present in the digestive system. Once complete, students can mark and correct their work using the answers provided in the PowerPoint.
Lastly, students are shown a diagram of the villi which are present in the small intestine. Students will need to describe the adaptations of the villi which aid the role of absorption of small molecules into the bloodstream. The final activity requires students to find ten word, all related to the digestive system, in a word search.
The plenary activity is a set of answers, students will need to write the questions which match up these answers.
