What’s included? ** 7Aa – Life Processes:** A structured lesson introducing the seven life processes (MRS GREN) and explaining how to identify living, dead and non-living things. ** 7Ab - Organs:** A lesson exploring the functions of different organs in the human body and how they contribute to essential life processes. ** 7Ac - Tissues:** A lesson explaining how groups of specialised cells work together to form tissues and perform particular functions. 7Ad - Cells: A lesson introducing cell structure and function, including the main components of plant and animal cells and their differences. ** 7Ae - Organ Systems: ** A lesson exploring how organs work together in organ systems and how different systems contribute to the functioning of the human body. Student information sheets and supporting resources: Resources to help students follow lesson content, consolidate key concepts and develop their understanding of important scientific terminology. Classroom activities and knowledge-check questions: Tasks and questions to reinforce learning, assess understanding and encourage students to apply their knowledge across the chapter. The bundle helps students develop a clear understanding of the organisation of living organisms, progressing from cells to tissues, organs and organ systems, while exploring the life processes that characterise living things. Ideal for Edexcel KS3 Science teachers looking for a comprehensive, classroom-ready bundle that provides consistent lesson resources across the whole chapter. Suitable for classroom teaching, revision, consolidation, homework and independent learning.
