The Digestive System - PowerPoint

The Digestive System is a vital topic covered in Year 4 Science, focusing on animals including humans. The curriculum resource provides an engaging PowerPoint presentation that guides students through the complex journey of food as it is transformed into energy. The presentation begins with an introduction to the digestive system, explaining its critical role in breaking down food into nutrients. This process starts in the mouth, where food is chewed and mixed with saliva, then travels down the oesophagus to the stomach. In the stomach, the food is further broken down by churning and acid before moving into the small intestine, where nutrients are absorbed into the bloodstream. The journey concludes in the large intestine, where water is absorbed and waste is formed.

The teaching resource includes interactive worksheets that encourage students to label the parts of the digestive system and arrange them in the order that food passes through. Additionally, the worksheets prompt students to match the functions of each digestive system part and answer questions about the process. To deepen their understanding, students are tasked with writing a short story about the journey of their lunch through the digestive system, considering each part and its role. This approach helps solidify their knowledge of the digestive system's function and the importance of each organ within it.
