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: 4.7.1.1 Relevant chapter: B16 Adaptations, interdependence and competitions. AQA Biology third edition textbook-Page 258-259 Students are required to know the following; Students should be able to describe: •different levels of organisation in an ecosystem from individual organisms to the whole ecosystem • the importance of interdependence and competition in a community. An ecosystem is the interaction of a community of living organisms (biotic) with the non-living (abiotic) parts of their environment. To survive and reproduce, organisms require a supply of materials from their surroundings and from the other living organisms there. Plants in a community or habitat often compete with each other for light and space, and for water and mineral ions from the soil. Animals often compete with each other for food, mates and territory. Within a community each species depends on other species for food, shelter, pollination, seed dispersal etc. If one species is removed it can affect the whole community. This is called interdependence. A stable community is one where all the species and environmental factors are in balance so that population sizes remain fairly constant.

( 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.

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.

Principles of hormonal control 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. AQA spec link: 5.3.1 Relevant chapter: B11 Hormonal coordination. AQA Biology third edition textbook-Page 160-161. *The new specification requires students to know the following; Students should be able to describe the principles of hormonal coordination and control by the human endocrine system. The endocrine system is composed of glands which secrete chemicals called hormones directly into the blood stream. The blood carries the hormone to a target organ where it produces an effect. Compared to the nervous system the effects are slower but act for longer. The pituitary gland in the brain is a ‘master gland’ which secretes several hormones into the blood in response to body conditions. These hormones in turn act on other glands to stimulate other hormones to be released to bring about effects. Students should be able to identify the position of the following on a diagram of the human body: • pituitary gland • pancreas • thyroid • adrenal gland • ovary • testes.

Vaccination lesson created in accordance to the NEW AQA Specification (9-1). Designed for a higher tier class, although content can be adjusted to suit any ability. Includes: embedded videos and timers, slide animations, practice questions with answers on slides. AQA spec link: 4.3.1.7 Relevant chapter: B6 Preventing and treating disease. AQA Biology third edition textbook-Page 98-99 Specification requires students to know the following; Students should be able to explain how vaccination will prevent illness in an individual, and how the spread of pathogens can be reduced by immunising a large proportion of the population. Vaccination involves introducing small quantities of dead or inactive forms of a pathogen into the body to stimulate the white blood cells to produce antibodies. If the same pathogen re-enters the body the white blood cells respond quickly to produce the correct antibodies, preventing infection. Students do not need to know details of vaccination schedules and side effects associated with specific vaccines.

Cell division (mitosis) lesson created in accordance to the NEW AQA Specification (9-1). Designed for a higher ability separates class, although content can be adjusted to suit any ability. Includes: slide animations, practice questions with answers on slides and worksheet. AQA spec link: 4.1.2.1 & 4.1.2.2 Relevant chapter: B2 Cell division. AQA Biology third edition textbook-Page 26-27 Specification requires students to know the following; The nucleus of a cell contains chromosomes made of DNA molecules. Each chromosome carries a large number of genes. In body cells the chromosomes are normally found in pairs. Cells divide in a series of stages called the cell cycle. Students should be able to describe the stages of the cell cycle, including mitosis. During the cell cycle the genetic material is doubled and then divided into two identical cells. Before a cell can divide it needs to grow and increase the number of sub-cellular structures such as ribosomes and mitochondria. The DNA replicates to form two copies of each chromosome. In mitosis one set of chromosomes is pulled to each end of the cell and the nucleus divides. Finally the cytoplasm and cell membranes divide to form two identical cells. Students need to understand the three overall stages of the cell cycle but do not need to know the different phases of the mitosis stage. Cell division by mitosis is important in the growth and development of multi-cellular organisms. Students should be able to recognise and describe situations in given contexts where mitosis is occurring.

Exchanging materials lesson created in accordance to the NEW AQA Specification (9-1). Designed for a higher ability separates class, although content can be adjusted to suit any ability. Includes: slide animations, practice questions with answers on slides, worksheet, and homework (with MS) AQA spec link: 4.1.3.1 Relevant chapter: B1 Cell structure and transport. AQA Biology third edition textbook-Page 22-23 Specification requires students to know the following; A single-celled organism has a relatively large surface area to volume ratio. This allows sufficient transport of molecules into and out of the cell to meet the needs of the organism. Students should be able to calculate and compare surface area to volume ratios. Students should be able to explain the need for exchange surfaces and a transport system in multicellular organisms in terms of surface area to volume ratio. Students should be able to explain how the small intestine and lungs in mammals, gills in fish, and the roots and leaves in plants, are adapted for exchanging materials. In multicellular organisms, surfaces and organ systems are specialised for exchanging materials. This is to allow sufficient molecules to be transported into and out of cells for the organism’s needs. The effectiveness of an exchange surface is increased by: •• having a large surface area •• a membrane that is thin, to provide a short diffusion path •• (in animals) having an efficient blood supply •• (in animals, for gaseous exchange) being ventilated.

DNA and the genome lesson created in accordance to the NEW AQA Specification (9-1). Designed for a TRILOGY 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. AQA spec link: 6.1.4 Relevant chapter: B13 Genetics and reproduction. AQA trilogy textbook-Page 166-167. Specification requires students to know the following; Students should be able to describe the structure of DNA and define genome. The genetic material in the nucleus of a cell is composed of a chemical called DNA. DNA is a polymer made up of two strands forming a double helix. The DNA is contained in structures called chromosomes. A gene is a small section of DNA on a chromosome. Each gene codes for a particular sequence of amino acids, to make a specific protein. The genome of an organism is the entire genetic material of that organism. The whole human genome has now been studied and this will have great importance for medicine in the future. Students should be able to discuss the importance of understanding the human genome. This is limited to the: • search for genes linked to different types of disease • understanding and treatment of inherited disorders • use in tracing human migration patterns from the past

AQA Biology combined textbook-Page 104-105 Students are required to know the following; • discuss the human and financial cost of these non-communicable diseases to an individual, a local community, a nation, or globally • explain the effect of lifestyle factors including diet, alcohol, and smoking on the incidence of non-communicable diseases at local, national, and global levels. Risk factors are linked to an increased rate of a disease. They can be: • aspects of a person’s lifestyle • substances in the person’s body or environment. A causal mechanism has been proven for some risk factors, but not in others. • The effects of diet and exercise on cardiovascular disease. • Obesity as a risk factor for Type 2 diabetes. Many diseases are caused by the interaction of a number of factors. Students should be able to understand the principles of sampling as applied to scientific data in terms of risk factors. Students should be able to translate information between graphical and numerical forms; and extract and interpret information from charts, graphs and tables in terms of risk factors. Students should be able to use a scatter diagram to identify a correlation between two variables in terms of risk factors.

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.

Growth and differentiation lesson created in accordance to the NEW AQA Specification (9-1). Designed for a higher ability separates class, although content can be adjusted to suit any ability. Includes: slide animations, embedded video, practice questions with answers on slides. AQA spec link: 4.1.1.4 Relevant chapter: B2 Cell division. AQA Biology third edition textbook-Page 28-29 Specification requires students to know the following; Students should be able to explain the importance of cell differentiation. As an organism develops, cells differentiate to form different types of cells. • Most types of animal cell differentiate at an early stage. ••Many types of plant cells retain the ability to differentiate throughout life. In mature animals, cell division is mainly restricted to repair and replacement. As a cell differentiates it acquires different sub-cellular structures to enable it to carry out a certain function. It has become a specialised cell.

Physical defence responses to resist invasion of microorganisms: • Cellulose cell walls. • Tough waxy cuticle on leaves. • Layers of dead cells around stems (bark on trees) which fall off. Chemical plant defence responses: • Antibacterial chemicals. • Poisons to deter herbivores. Mechanical adaptations: • Thorns and hairs deter animals. • Leaves which droop or curl when touched. • Mimicry to trick animals.

Removing waste products lesson created in accordance to the NEW AQA Specification (9-1) for my separates class (Year 10-KS4). Includes: slide animations and worksheet. AQA spec link: 5.3.3 Relevant chapter: B12.2-Removing waste products . ( Note: This topic is for BIOLOGY only not for combined science students). AQA Biology third edition textbook-Page 184-185 *The new specification requires students to know the following; Students should be able to explain the effect on cells of osmotic changes in body fluids. Water leaves the body via the lungs during exhalation. Water, ions, and urea are lost from the skin in sweat. There is no control over water, ion, or urea loss by the lungs or skin. Excess water, ions, and urea are removed via the kidneys in the urine. If body cells lose or gain too much water by osmosis they do not function efficiently. The digestion of proteins from the diet results in excess amino acids which need to be excreted safely. In the liver these amino acids are deaminated to form ammonia. Ammonia is toxic and so it is immediately converted to urea for safe excretion.

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.
