This lesson created in accordance to the NEW AQA Specification (9-1) for my separates class (Year 10-KS4). I taught this lesson after the required germination practical. Includes: slide animations, embedded video and practice questions with mark scheme. This resource is for separates ONLY. *NOTE-using plant hormones-Higher tier only* AQA spec link: 5.4.1, 5.4.2 Relevant chapter: B11.9/10- AQA Biology third edition textbook-Page 176-179 *The new specification requires students to know the following; Plants produce hormones to coordinate and control growth and responses: to light, phototropism; and gravity, gravitropism (geotropism). Unequal distributions of auxin cause unequal growth rates in plant roots and shoots. Gibberellins are important in initiating seed germination. Ethene controls cell division and ripening of fruits. The mechanisms of how gibberellins and ethene work are not required. Students should be able to describe the effects of some plant hormones and the different ways people use them to control plant growth. Plant growth hormones are used in agriculture and horticulture. Auxins are used as: • as weed killers • as rooting powders • for promoting growth in tissue culture. Ethene is used in the food industry to control ripening of fruit during storage and transport. Gibberellins can be used to: • end seed dormancy • promote flowering • increase fruit size.

DNA and the genome lesson created in accordance to the NEW AQA Specification (9-1). Designed for a separates class, although content can be adjusted to suit any ability. Includes: embedded videos and timers, slide animations, practice questions with answers on slides and an interactive quiz. AQA spec link: 6.1.4 Relevant chapter: B13 Genetics and reproduction. AQA Biology third edition textbook-Page 202-203. 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.

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.

The response to exercise 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: 4.4.2.2 Relevant chapter: B9 Respiration. AQA Biology third edition textbook-Page 136-137 Students are required to know the following; During exercise the human body reacts to the increased demand for energy. The heart rate, breathing rate and breath volume increase during exercise to supply the muscles with more oxygenated blood. If insufficient oxygen is supplied anaerobic respiration takes place in muscles. The incomplete oxidation of glucose causes a build up of lactic acid and creates an oxygen debt. During long periods of vigorous activity muscles become fatigued and stop contracting efficiently. AT 1, 3, 4 Investigations into the effect of exercise on the body. (HT only) Blood flowing through the muscles transports the lactic acid to the liver where it is converted back into glucose. Oxygen debt is the amount of extra oxygen the body needs after exercise to react with the accumulated lactic acid and remove it from the cells.

Metabolism and the liver 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: 4.4.2.1 Relevant chapter: B9 Respiration. AQA Biology third edition textbook-Page 140-141 Students are required to know the following; Students should be able to explain the importance of sugars, amino acids, fatty acids and glycerol in the synthesis and breakdown of carbohydrates, proteins and lipids. Metabolism is the sum of all the reactions in a cell or the body. The energy transferred by respiration in cells is used by the organism for the continual enzyme controlled processes of metabolism that synthesise new molecules. Metabolism includes: •conversion of glucose to starch, glycogen and cellulose •the formation of lipid molecules from a molecule of glycerol and three molecules of fatty acids • the use of glucose and nitrate ions to form amino acids which in turn are used to synthesise proteins • respiration •breakdown of excess proteins to form urea for excretion. All of these aspects are covered in more detail in the relevant specification section but are linked together here.

Helping the heart 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. **Depending on the ability of the class and time , the content included could take up two lessons, the last activity can be done as a role play. ** 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: 4.2.2.4 Relevant chapter: B4 Organising animals and plants. AQA Biology combined/third edition textbook-Page 57-59 Students are required to know the following; Students should be able to evaluate the advantages and disadvantages of treating cardiovascular diseases by drugs, mechanical devices or transplant. In coronary heart disease layers of fatty material build up inside the coronary arteries, narrowing them. This reduces the flow of blood through the coronary arteries, resulting in a lack of oxygen for the heart muscle. Stents are used to keep the coronary arteries open. Statins are widely used to reduce blood cholesterol levels which slows down the rate of fatty material deposit. In some people heart valves may become faulty, preventing the valve from opening fully, or the heart valve might develop a leak. Students should understand the consequences of faulty valves. Faulty heart valves can be replaced using biological or mechanical valves. In the case of heart failure a donor heart, or heart and lungs can be transplanted. Artificial hearts are occasionally used to keep patients alive whilst waiting for a heart transplant, or to allow the heart to rest as an aid to recovery.

***Please note this is two lessons comnined into one. *** Tissues, organs and transport systems 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: 4.2.3.1 Relevant chapter: B4 Organising animals and plants. AQA Biology combined/third edition textbook-Page 62-65 Students are required to know the following Students should be able to explain how the structures of plant tissues are related to their functions. Plant tissues include: • epidermal tissues • palisade mesophyll • spongy mesophyll •xylem and phloem •meristem tissue found at the growing tips of shoots and roots. The leaf is a plant organ. Knowledge limited to epidermis, palisade and spongy mesophyll, xylem and phloem, and guard cells surrounding stomata. Students should be able to explain how the structure of root hair cells, xylem and phloem are adapted to their functions. Root hair cells are adapted for the efficient uptake of water by osmosis, and mineral ions by active transport. Xylem tissue transports water and mineral ions from the roots to the stems and leaves. It is composed of hollow tubes strengthened by lignin adapted for the transport of water in the transpiration stream. The role of stomata and guard cells are to control gas exchange and water loss. Phloem tissue transports dissolved sugars from the leaves to the rest of the plant for immediate use or storage. The movement of food molecules through phloem tissue is called translocation. Phloem is composed of tubes of elongated cells. Cell sap can move from one phloem cell to the next through pores in the end walls. Detailed structure of phloem tissue or the mechanism of transport is not required.

Thermoregulation 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. AQA spec link: 5.2.4 Relevant chapter: B12-Homeostasis in action. ( Note: This topic is for BIOLOGY only not for combined science students). AQA Biology third edition textbook-Page 182-183 *The new specification requires students to know the following; Body temperature is monitored andcontrolled by the thermoregulatory centre in the brain. The thermoregulatory centre contains receptors sensitive to the temperature of the blood. The skin contains temperature receptorsand sends nervous impulses to the thermoregulatory centre. If the body temperature is too high, blood vessels dilate (vasodilation) and sweat is produced from the sweat glands.Both these mechanisms cause a transfer of energy from the skin to the environment. If the body temperature is too low, blood vessels constrict (vasoconstriction), sweating stops, and skeletal muscles contract (shiver). Students should be able to explain how these mechanisms lower or raise body temperature in a given context.

Fossils and extinction lesson created in accordance to the NEW AQA Specification (9-1). Designed for higher ability (trilogy/combined) class, although content can be adjusted to suit any ability. 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: 4.6.3.5 Relevant chapter: B14 Genetics and evolution. 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.

AQA Biology third edition textbook-Page 42-43 Students are required to know the following; Students should be able to relate knowledge of enzymes to metabolism. Students should be able to carry out rate calculations for chemical reactions. Enzymes catalyse specific reactions in living organisms due to the shape of their active site. Students should be able to use the ‘lock and key theory’ as a simplified model to explain enzyme action. Students should be able to explain the importance of sugars, amino acids, fatty acids, and glycerol in the synthesis and breakdown of carbohydrates, proteins, and lipids. Metabolism is the sum of all the reactions in a cell or the body. The energy transferred by respiration in cells is used by the organism for the continual enzyme controlled processes of metabolism that synthesise new molecules.

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.

Aerobic respiration 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: 4.4.2.1 Relevant chapter: B9 Respiration. AQA Biology third edition textbook-Page 134-135 Students are required to know the following; Students should be able to describe cellular respiration as an exothermic reaction which is continuously occurring in living cells. The energy transferred supplies all the energy needed for living processes. Respiration in cells can take place aerobically (using oxygen) or anaerobically (without oxygen), to transfer energy. Students should be able to compare the processes of aerobic and anaerobic respiration with regard to the need for oxygen, the differing products and the relative amounts of energy transferred. Organisms need energy for: •• chemical reactions to build larger molecules •• movement •• keeping warm. Aerobic respiration is represented by the equation: glucose + oxygen carbon dioxide + water Students should recognise the chemical symbols: C6H12O6, O2, CO2 and H2O.

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.

Edited 13/07/2020-PPT has been updated since last review, this resource also now includes a Control of BGL mini assessment with MS Control of blood glucose lesson created in accordance to the NEW AQA Specification (9-1) for my separates class (Year 10-KS4). Includes: slide animations, embedded video, practice exam question with mark scheme. This resource is suitable for combined science students. May needed to be edited for foundation students. AQA spec link: 5.3.2 Relevant chapter: B11 Hormonal coordination. AQA Biology third edition textbook-Page 162-163. Blood glucose concentration is monitored and controlled by the pancreas. If the blood glucose concentration is too high, the pancreas produces the hormone insulin that causes glucose to move from the blood into the cells. In liver and muscle cells excess glucose is converted to glycogen for storage. Students should be able to explain how insulin controls blood glucose (sugar) levels in the body. Type 1 diabetes is a disorder in which the pancreas fails to produce sufficient insulin. It is characterised by uncontrolled high blood glucose levels. In Type 2 diabetes the body cells no longer respond to insulin produced by the pancreas. Students should be able to compare Type 1 and Type 2 diabetes and explain how they can be treated. Students should be able to extract information and interpret data from graphs that show the effect of insulin in blood glucose levels in both people with diabetes and people without diabetes. (Will be incorporated in treating diabetes lesson). Higher content- If the blood glucose concentration is too low, the pancreas produces the hormone glucagon that causes glycogen to be converted into glucose and released into the blood. Students should be able to explain how glucagon interacts with insulin in a negative feedback cycle to control blood glucose (sugar) levels in the body. (Will be mentioned in negative feedback lesson)
