The Transport of Water and Nutrients - Lesson Plan

The lesson plan from The Primary Science Advisory Service Ltd focuses on the transport of water and nutrients around the body, specifically exploring the function of the kidneys and the process of osmosis. The session aims to enhance students' scientific skills, such as planning investigations, presenting and analysing data, and evaluating investigations. It encourages pattern seeking and research using secondary resources. The curriculum content aligns with the National Curriculum, providing a deeper understanding of how water and nutrients are transported within animals, including humans. Students will explore how osmosis contributes to nutrient movement and the kidneys' role in water removal. The lesson builds on previous learning from early years to Year 6, gradually introducing concepts like the human body's basic parts, the needs of animals for survival, and the functions of the circulatory system.

During the lesson, students will conduct an osmosis experiment using potatoes, salt, and water to observe the effects of different salt concentrations on the potatoes' length, colour, texture, and firmness. This practical activity will help students understand how osmosis affects the movement of water in living organisms. Additionally, they will undertake a creative project to design and build a model kidney, applying their understanding of the urinary system and filtration. The lesson incorporates cross-curricular links with maths and design technology, and health and safety considerations are highlighted to ensure a safe learning environment. Through these activities, students will correct common misconceptions about the kidneys, learn key scientific terms, and engage with the historical contributions of influential scientists to the understanding of human anatomy and physiology.
