1 of 4 The National Strategies Secondary Secondary Framework in Science, Life processes: reproduction 2.1 Life processes: reproduction Year Yearly learning objectives Amplification – pupils could learn to Strategies for progression Rich questions 7 describe the role of organ systems in plants and animals that can contribute to the seven life processes use scientific terminology to describe the main parts of the reproductive systems in animals and plants and describe their location Create opportunities for pupils to compare and contrast different models used to explain the function of the reproductive systems of plants and animals. Are plants male and female? describe and compare, in simple terms, the processes of pollination, fertilisation, seed dispersal and germination Support pupils in exploring possible misconceptions they might have about reproduction, e.g. plants don’t reproduce sexually; reproduction is equivalent to sexual intercourse. Plan opportunities for pupils to explain patterns in data related to different methods of reproduction in vertebrates, and use this to explain the advantages of internal development. Can animals reproduce without sex? Do plants have sex? Why have males and females? If eggs are oval, why is the yolk round? Create opportunities for pupils to discuss and agree criteria to help them evaluate how well, for example, the uterus, testes and flower are adapted to their function. 8 explain how the organs and tissues in plants and animals function to support the seven life processes in a healthy organism explain, using suitable models and analogies, the functions of major organs and tissues in the reproductive systems in plants and animals explain how some factors can impact on reproduction, e.g. poor nutrition, diet Involve pupils in creating and assessing their own models to explain the adaptations of organs, tissues or cells that occur in the reproductive systems of plants and animals. Provide opportunities for pupils to use evidence to explain the advantages and disadvantages of sexual and asexual reproduction in a variety of organisms (including simple organisms). Do plants become sexually active? Are rabbits fast breeders? Do pregnant women need to eat for two? Do fertilisers help plants reproduce?

What is a clone? Involve pupils in identifying and presenting scientific arguments for a specific audience around a controversial issue, e.g. ‘Should conjoined twins be separated?’, ‘Should there be an age limit for in vitro fertilisation (IVF) treatment?’, ‘Should all people have the right to be a parent?’ What is a fruit? Is breast best? Is a sperm an egg with a tail? Have potatoes got eyes? Do hermaphrodites have a solitary existence? Plan for structured, focused discussion and research to identify how the other organ systems can support the process of reproduction. Create opportunities for pupils to compare the strengths and weaknesses of different models to explain the menstrual cycle and decide if the model is good enough. Model for pupils how to distinguish between scientific evidence and opinion when exploring the impact of a range of factors on successful reproduction, e.g. anorexia nervosa, sexually transmitted diseases (STDs), hormone imbalance. 00215-2009PDF-EN-01 © Crown copyright 2009 3 of 4 The National Strategies Secondary Secondary Framework in Science, Life processes: reproduction Year Yearly learning objectives Amplification – pupils could learn to Strategies for progression Rich questions 10 explain how individual intracellular and extracellular processes and structures in plants and animals support the seven life processes apply scientific understanding together with evidence to: Involve pupils in discussing the role of science in solving problems and the range of issues that can arise as a result, e.g. increasing crop production through GM crops or cloning. Can scientists solve the world food shortage? explain why certain chemical, physical and biological factors can disrupt the seven life processes – compare different ways of preventing and curing diseases related to the reproductive organs, e.g. human immunodeficiency virus (HIV), STDs, problems with infertility. – explain how diseases and external substances affect the reproductive systems, e.g. smoking, alcohol, endometriosis, hormonal imbalances explain how different processes link the reproductive system to other systems in the organism, e.g. respiration, diffusion, digestion, excretion evaluate the models and analogies used to explain the menstrual cycle in order to clarify thinking and distinguish between ovulation and fertilisation 11 explain how the different intracellular and extracellular processes work together to support life in familiar contexts evaluate the impact of chemical, physical and biological factors and explain their effects on the life processes 00215-2009PDF-EN-01 evaluate different models to explain how processes link to the overall process of reproduction, e.g. the endocrine system and different hormones in bringing about fertilisation, implantation, birth and lactation; the circulatory, respiratory and excretory systems explain and evaluate the benefits and drawbacks, including ethical, moral, social and political aspects, of some related applications and implications of science, such as: Create opportunities for pupils to present a complex scientific case to influence the responses of others, e.g. storage of embryos for experimentation. Create opportunities for pupils to research and critically analyse data related to the transmission of HIV or genetic screening. Involve pupils in evaluating each other’s models to explain blood flow through the placenta. What makes a population explode? Should genetic screening be compulsory? Regeneration – fact or fiction? Is boom and bust good for populations? Provide opportunities for pupils to research and evaluate common models used to explain how processes are coordinated, e.g. menstruation, birth, sperm production. Create opportunities for pupils to devise criteria to evaluate claims made in newspapers or scientific articles, e.g. about stem-cell research Create opportunities for pupils to evaluate a piece of research, scientific article or other pupils’ work on the response of reproductive systems to stressful conditions, e.g. drought, lack of food, competition for mates, adverse weather conditions (like in the Arctic). What determines gender? Why are stem cells so valuable? Do we need males?

Rich questions – genetic screening – use of hormones to control pregnancy, menstruation and HRT – amniotic tests for Down’s syndrome – storage of embryos for later use Extension use and apply their understanding of how life processes in organisms work together in unfamiliar contexts critically evaluate the relative impact of chemical, physical and biological factors and their effect on life processes in unfamiliar contexts 00215-2009PDF-EN-01 explore and explain how different reproductive behaviours change in more stressful situations and how organs, tissues and cells work to bring this about, e.g. high levels of competition, shortages of food evaluate critically a range of secondary evidence used to support and negate claims related to improving reproduction, e.g. genetic modification, cloning, IVF © Crown copyright 2009
