Measure the population size of a common species in a habitat. Use sampling techniques to investigate the effect of a factor on the distribution of this species. This lesson was conducted outdoors hence why a powerpoint was not created. This investigation has two parts: Investigating the population size of a plant species using random sampling Investigating the effect of a factor on plant distribution using a transect line.

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.

Diffusion 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 videos and practice questions with answers on slides, worksheet. Due to the size of this topic, exchanging materials and surface area will be taught in a separate lesson. AQA spec link: 4.1.3.1 Relevant chapter: B1 Cell structure and transport. AQA Biology third edition textbook-Page 14-15 Specification requires students to know the following; Substances may move into and out of cells across the cell membranes via diffusion. Diffusion is the spreading out of the particles of any substance in solution, or particles of a gas, resulting in a net movement from an area of higher concentration to an area of lower concentration. Some of the substances transported in and out of cells by diffusion are oxygen and carbon dioxide in gas exchange, and of the waste product urea from cells into the blood plasma for excretion in the kidney. Students should be able to explain how different factors affect the rate of diffusion. Factors which affect the rate of diffusion are: •• the difference in concentrations (concentration gradient) •• the temperature •• the surface area of the membrane.

Antibiotic resistant bacteria lesson created in accordance to the NEW AQA Specification (9-1). Designed for higher ability 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: 4.6.3.7 Relevant chapter: B14 Genetics and evolution. AQA combined trilogy edition textbook-Page 196-197 Students are required to know the following; Bacteria can evolve rapidly because they reproduce at a fast rate. Mutations of bacterial pathogens produce new strains. Some strains might be resistant to antibiotics, and so are not killed. They survive and reproduce, so the population of the resistant strain rises. The resistant strain will then spread because people are not immune to it and there is no effective treatment. MRSA is resistant to antibiotics. To reduce the rate of development of antibiotic resistant strains: • doctors should not prescribe antibiotics inappropriately, such as treating non-serious or viral infections • patients should complete their course of antibiotics so all bacteria are killed and none survive to mutate and form resistant strains •the agricultural use of antibiotics should be restricted. The development of new antibiotics is costly and slow. It is unlikely to keep up with the emergence of new resistant strains.

Anaerobic 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 138-139 Students are required to know the following; Anaerobic respiration in muscles is represented by the equation: glucose lactic acid. As the oxidation of glucose is incomplete in anaerobic respiration much less energy is transferred than in aerobic respiration. Anaerobic respiration in plant and yeast cells is represented by the equation: glucose --> ethanol + carbon dioxide Anaerobic respiration in yeast cells is called fermentation and has economic importance in the manufacture of bread and alcoholic drinks.

How the digestive system works 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: 4.2.2.1 Relevant chapter: B3 Organisation and the digestive system. AQA Biology third edition textbook-Page 46-47 Students are required to know the following; Students should be able to recall the sites of production and the action of amylase, proteases and lipases. Students should be able to understand simple word equations but no chemical symbol equations are required. Digestive enzymes convert food into small soluble molecules that can be absorbed into the bloodstream. Carbohydrases break down carbohydrates to simple sugars. Amylase is a carbohydrase which breaks down starch. Proteases break down proteins to amino acids. Lipases break down lipids (fats) to glycerol and fatty acids. The products of digestion are used to build new carbohydrates, lipids and proteins. Some glucose is used in respiration.
