      Presenting the human digestive system

      Lesson details

      Learning outcome

      I can present and communicate information about the human digestive system.

      Key learning points

      1. When humans eat food, it travels from the mouth to the toilet through the digestive system.
      2. It is important for scientists to communicate their findings to other people.
      3. A flowchart is a diagram, using boxes, lines and arrows, that shows the steps of a process from beginning to end.
      4. Scientists use scientific vocabulary in their explanations.
      5. Presentations can vary in format, including verbal and written explanations.

      Keywords

      • Digestive system - The digestive system is all the organs in the body that break down and digest food. They are linked from the mouth to the anus.

      • Communicate - To communicate is to share or exchange information or ideas.

      • Flowchart - A flowchart is a diagram that shows the steps of a process from beginning to end.

      • Presentation - A presentation conveys information from a speaker to an audience.

      Common misconception

      Pupils may not realise there are many ways to present information as well as writing.

      By sharing many ways that information is communicated throughout the lesson, pupils will have a variety of ways that they can choose to present what they have learned about the digestive system.

      Teacher tip

      Discuss lots of different ways that people share information such as teachers, politicians, authors, scientists, public announcers, and journalists and discuss how it depends on who their audience is.

      Equipment

      This will depend on how the pupils choose to present their information about the digestive system.
