The human Kidney lesson created in accordance to the NEW AQA Specification (9-1) for my separates class (Year 10-KS4). This is a printer friendly resource it includes an: embedded video, slide animations and a mini exam question. As i taught this lesson in two parts it's only fair i upload the other presentation also (2 for the price of 1). **Knowledge of other parts of the urinary system, the structure of the kidney, and the structure of a nephron is not required.** AQA spec link: 5.3.3 Relevant chapter: B12-Homeostasis in action. ( Note: This topic is for BIOLOGY only not for combined science students). AQA Biology third edition textbook-Page 185-186 *The new specification requires students to know the following; Students should be able to describe the function of kidneys in maintaining the water balance of the body. The kidneys produce urine by filtration of the blood and selective reabsorption of useful substances such as glucose, some ions, And water. Knowledge of other parts of the urinary system, the structure of the kidney, and the structure of a nephron is not required. Students should be able to translate tables and bar charts of glucose, ions, and urea before and after filtration. Students should be able to describe the effect of ADH on the permeability of the kidney tubules. The water level in the body is controlled by the hormone ADH which acts on the kidney tubules. ADH is released by the pituitary gland when the blood is too concentrated and it causes more water to be reabsorbed back into the blood from the kidney tubules. This is controlled by negative feedback.

Common problems of the eye lesson created in accordance to the NEW AQA Specification (9-1). Designed for a higher ability, separate science class, although content can be adjusted to suit any ability.

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.

AQA Biology trilogy edition textbook-Page 192-193 Students are required to know the following; Fossils are the ‘remains’ of organisms from millions of years ago, which are found in rocks. Fossils may be formed: • from parts of organisms that have not decayed because one or more of the conditions needed for decay are absent • when parts of the organism are replaced by minerals as they decay •as preserved traces of organisms, such as footprints, burrows and rootlet traces. Many early forms of life were soft-bodied, which means that they have left few traces behind. What traces there were have been mainly destroyed by geological activity. This is why scientists cannot be certain about how life began on Earth. WS 1.3 Appreciate why the fossil record is incomplete.

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.

NB-This resource has been edited since the last review* [30/9/17] Screening for genetic disorders lesson created in accordance to the NEW AQA Specification (9-1). Designed for a higher ability TRILOGY(combined science) class, although content can be adjusted to suit any ability. Includes: slide animations, embedded videos and practice questions with answers on slides as well as a quiz. This video contains many videos and is a great lesson to spark a debate. I'd appreciate a review after your lesson :) AQA spec link: 6.1.7 Relevant chapter: B13 Genetics and reproduction. AQA Biology third edition textbook-Page 214-215. Some disorders are inherited. These disorders are caused by the inheritance of certain alleles. • Polydactyly (having extra fingers or toes) is caused by a dominant allele. • Cystic fibrosis (a disorder of cell membranes) is caused by a recessive allele. Students should make informed judgements about the economic, social and ethical issues concerning embryo screening, given appropriate information. WS 1.3 Appreciate that embryo screening and gene therapy may alleviate suffering but consider the ethical issues which arise.

This lesson has been created in accordance to the NEW AQA Specification (9-1) for my combined/additional science class (Year 9-KS4). Includes: slide animations, embedded video, worksheet and answers have also been included within the slides. This resource is suitable for separate science students. AQA spec link: 4.3.1.4 and 4.3.1.5 Relevant chapter: B5-Communicable diseases . AQA Biology third edition textbook-Page 88-89. *The new specification requires students to know the following; Rose black spot is a fungal disease where purple or black spots develop on leaves, which often turn yellow and drop early. It affects the growth of the plant as photosynthesis is reduced. It is spread in the environment by water or wind. Rose black spot can be treated by using fungicides and/or removing and destroying the affected leaves. The pathogens that cause malaria are protists. The malarial protist has a life cycle that includes the mosquito. Malaria causes recurrent episodes of fever and can be fatal. The spread of malaria is controlled by preventing the vectors, mosquitos, from breeding and by using mosquito nets to avoid being bitten.

Material cycling lesson created in accordance to the NEW AQA Specification (9-1). Designed for a higher ability class, although content can be adjusted to suit any ability. Includes powerpoint timers, slide animations, embedded video’s and mini review. NB: If you are unable to play embedded videos please view slide notes for link. AQA spec link: 4.7.2.2 Relevant chapter: B17 organising an ecosystem. AQA Biology third edition textbook-Page 278-279 Students are required to know the following; Explain the importance of the carbon and water cycles to living organisms. All materials in the living world are recycled to provide the building blocks for future organisms. The carbon cycle returns carbon from organisms to the atmosphere as carbon dioxide to be used by plants in photosynthesis. The water cycle provides fresh water for plants and animals on land before draining into the seas. Water is continuously evaporated and precipitated. Students are not expected to study the nitrogen cycle. Students should be able to explain the role of microorganisms in cycling materials through an ecosystem by returning carbon to the atmosphere as carbon dioxide and mineral ions to the soil.

Adapt and survive lesson created in accordance to the NEW AQA Specification (9-1). Designed for a higher ability class, although content can be adjusted to suit any ability. Includes powerpoint timers, slide animations, embedded video’s and mini review. NB: If you are unable to play embedded videos please view slide notes for link. AQA spec link: 4.7.1.4 Students should be able to explain how organisms are adapted to live in their natural environment, given appropriate information. Organisms have features (adaptations) that enable them to survive in the conditions in which they normally live. These adaptations may be structural, behavioural, or functional. Some organisms live in environments that are very extreme, such as at high temperature, pressure, or salt concentration. These organisms are called extremophiles. Bacteria living in deep sea vents are extremophiles.

Adult cell cloning lesson created in accordance to the NEW AQA Specification (9-1). Designed for higher ability separates class, although content can be adjusted to suit any ability.

THIS LESSON IS FOR BIOLOGY ONLY AQA spec link: 4.5.2.2 Relevant chapter: B10 The human nervous system. AQA Biology Third edition textbook-Page 152-153 Students are required to know the following; The brain controls complex behaviour. It is made of billions of interconnected neurones and has different regions that carry out different functions. Students should be able to identify the cerebral cortex, cerebellum and medulla on a diagram of the brain, and describe their functions. (HT only) Students should be able to explain some of the difficulties of investigating brain function and treating brain damage and disease. (HT only) Neuroscientists have been able to map the regions of the brain to particular functions by studying patients with brain damage, electrically stimulating different parts of the brain and using MRI scanning techniques. The complexity and delicacy of the brain makes investigating and treating brain disorders very difficult.
