This sample scheme of work provides examples of 8 lessons to teach a unit on growth and development for GCSE 21st Century Science Biology. Each lesson outlines learning objectives, suggested teaching activities, resources, and key specification points. The lessons cover topics such as multicellular organisms, embryo development, plant development, cloning plants, phototropism, mitosis, meiosis, and DNA. Practical activities are suggested, such as looking at plant and animal cells under microscopes. The lessons emphasize that specialized cells form tissues and organs and stem cells allow growth and regeneration.
