Includes powerpoint timers, slide animations, embedded video’s, worksheet and mini review. NB: If you are unable to play embedded videos please view slide notes for link. AQA spec link: 4.5.1 Relevant chapter: B10 The human nervous system. AQA Biology combined edition textbook-Page 133-134 Students are required to know the following; Students should be able to explain that homeostasis is the regulation of the internal conditions of a cell or organism to maintain optimum conditions for function in response to internal and external changes. Homeostasis maintains optimal conditions for enzyme action and all cell functions. In the human body, these include control of: • blood glucose concentration • body temperature • water levels. These automatic control systems may involve nervous responses or chemical responses. All control systems include: • cells called receptors, which detect stimuli (changes in theenvironment) • coordination centres (such as the brain, spinal cord and pancreas) that receive and process information from receptors • effectors, muscles or glands, which bring about responses which restore optimum levels.

AQA Biology combined edition textbook-Page 224-225 Students are required to know the following; Students should understand that photosynthetic organisms are the producers of biomass = for life on Earth. Feeding relationships within a community can be represented by food chains. All food chains begin with a producer which synthesises molecules. This is usually a green plant or alga which makes glucose by photosynthesis. Producers are eaten by primary consumers, which in turn may be eaten by secondary consumers and then tertiary consumers. Consumers that kill and eat other animals are predators, and those eaten are prey. In a stable community the numbers of predators and prey rise and fall in cycles. WS 1.2 Interpret graphs used to model predator-prey cycles. Students should be able to interpret graphs used to model these cycles.

THIS LESSON IS FOR BIOLOGY ONLY AQA spec link: 4.5.2.3 Relevant chapter: B10 The human nervous system. AQA Biology Third edition textbook-Page 156-157 Students are required to know the following; Students should be able to relate the structures of the eye to their functions. This includes: • accommodation to focus on near or distant objects Accommodation is the process of changing the shape of the lens to focus on near or distant objects. To focus on a near object: • the ciliary muscles contract • the suspensory ligaments loosen • the lens is then thicker and refracts light rays strongly. To focus on a distant object: • the ciliary muscles relax • the suspensory ligaments are pulled tight • the lens is then pulled thin and only slightly refracts light rays. Two common defects of the eyes are myopia (short sightedness) and hyperopia (long sightedness) in which rays of light do not focus on the retina. • Generally these defects are treated with spectacle lenses which refract the light rays so that they do focus on the retina. • New technologies now include hard and soft contact lenses, laser surgery to change the shape of the cornea, and a replacement lens in the eye. Students should be able to interpret ray diagrams, showing these two common defects of the eye and demonstrate how spectacle lenses correct them.

Theories of evolution lesson created in accordance to the NEW AQA Specification (9-1). Designed for a separates class. Includes: embedded videos and timers, slide animations, practice questions with answers on slides, worksheet and an interactive quiz. NB: If you are unable to play videos a URL link can be found in the slide notes. AQA spec link: 4.6.3.1 Relevant chapter: B15 Genetics and evolution. AQA Biology trilogy edition textbook-Page 236-237 Students are required to know the following; Charles Darwin, largely as a result of observations on a round the world expedition, linked to developing knowledge of geology and fossils, proposed the theory of natural selection: • Individual organisms within a particular species show a wide range of variation for a characteristic. • Individuals with characteristics most suited to the environment are more likely to survive to breed successfully. • The characteristics that have enabled these individuals to survive are then passed on to the next generation. Other theories, including that of Jean-Baptiste Lamarck, are based mainly on the idea that changes that occur in an organism during its lifetime can be inherited. We now know that in the vast majority of cases this type of inheritance cannot occur. A study of creationism is not required.

AQA Biology third edition textbook-Page 242-243 Students are required to know the following; Students should be able to describe the evidence for evolution including fossils and antibiotic resistance in bacteria. The theory of evolution by natural selection is now widely accepted. Evidence for Darwin’s theory is now available as it has been shown that characteristics are passed on to offspring in genes. There is further evidence in the fossil record and the knowledge of how resistance to antibiotics evolves in bacteria.

The artificial control of fertility (contraception) lesson created in accordance to the NEW AQA Specification (9-1) for my separates class (Year 10-KS4). Includes: slide animations, embedded video and practice questions (homework) with mark scheme. This resource is suitable for combined science students. AQA spec link:5.3.5 Relevant chapter: B11.7-The artificial control of fertility . AQA Biology third edition textbook-Page 172-173. *The new specification requires students to know the following; Students should be able to evaluate the different hormonal and non-hormonal methods of contraception. Fertility can be controlled by a variety of hormonal and non-hormonal methods of contraception. These include: • oral contraceptives that contain hormones to inhibit FSH production so that no eggs mature • injection, implant, or skin patch of slow release progesterone to inhibit the maturation and release of eggs for a number of months or years • barrier methods such as condoms and diaphragms which prevent the sperm reaching an egg • intrauterine devices which prevent the implantation of an embryo or release a hormone • spermicidal agents which kill or disable sperm • abstaining from intercourse when an egg may be in the oviduct • surgical methods of male and female sterilisation.

Infertility treatments lesson created in accordance to the NEW AQA Specification (9-1) for my separates class (Year 10-KS4). Includes: slide animations, embedded video, worksheet and practice questions with mark scheme. This resource is suitable for combined science students. *Note-For higher tier only* AQA spec link:5.3.6 Relevant chapter: B11.8-Infertility treatments . AQA Biology third edition textbook-Page 174-175. *The new specification requires students to know the following; Students should be able to explain the use of hormones in modern reproductive technologies to treat infertility. This includes giving FSH and LH in a ‘fertility drug’ to a woman. She may then become pregnant in the normal way. In Vitro Fertilisation (IVF) treatment: • IVF involves giving a mother FSH and LH to stimulate the maturation of several eggs. • The eggs are collected from the mother and fertilised by sperm from the father in the laboratory. • The fertilised eggs develop into embryos. • At the stage when they are tiny balls of cells, one or two embryos are inserted into the mother’s uterus (womb). Although fertility treatment gives a woman the chance to have a baby of her own: • it is very emotionally and physically stressful • the success rates are not high • it can lead to multiple births which are a risk to both the babies and the mother.
