AQA Biology third edition textbook-Page 126-127 Students are required to know the following; Students should be able to explain the effects of temperature, light intensity, carbon dioxide concentration, and the amount of chlorophyll on the rate of photosynthesis. Students should be able to: • measure and calculate rates of photosynthesis • extract and interpret graphs of photosynthesis rate involving one limiting factor •plot and draw appropriate graphs selecting appropriate scale for axes •translate information between graphical and numeric form. Solve simple algebraic equations. MS 1a, 1c, 2c, 4a, 4c (HT only) These factors interact and any one of them may be the factor that limits photosynthesis. (HT only) Students should be able to explain graphs of photosynthesis rate involving two or three factors and decide which is the limiting factor. (HT only) Students should understand and use inverse proportion – the inverse square law and light intensity in the context of photosynthesis.

Selective breeding 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.

NB: If you are unable to play videos a URL link can be found in the slide notes. AQA spec link: 4.6.2.3 Relevant chapter: B13 Variation and evolution. AQA Biology trilogy edition textbook-Page 182-183. Students are required to know the following; Students should be able to explain the impact of selective breeding of food plants and domesticated animals. Selective breeding (artificial selection) is the process by which humans breed plants and animals for particular genetic characteristics. Humans have been doing this for thousands of years since they first bred food crops from wild plants and domesticated animals. Selective breeding involves choosing parents with the desired characteristic from a mixed population. They are bred together. From the offspring those with the desired characteristic are bred together. This continues over many generations until all the offspring show the desired characteristic. The characteristic can be chosen for usefulness or appearance: • Disease resistance in food crops. • Animals which produce more meat or milk. • Domestic dogs with a gentle nature. • Large or unusual flowers. Selective breeding can lead to ‘inbreeding’ where some breeds are particularly prone to disease or inherited defects. WS 1.3, 1.4 Explain the benefits and risks of selective breeding given appropriate information and consider related ethical issues.

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.

Investigate the effect of pH on the rate of reaction (RP 5-separate science). This practical was completed in one lesson, students were asked to construct a graph from their data for homework. How did i deliver this practical? I used 5 different buffered pH solutions (4,5,6,7,8). I split my class into two groups ( 2 x 15). Within each group there were 5 sub-groups. This allowed me to gather two sets of results for each pH. Group A Group B | Student group 1-pH 4 | Student group 1-pH 4 | Student group 2-pH 5 | Student group 2-pH 5 | Student group 3-pH 6 | Student group 3-pH 6 | Student group 4-pH 7 | Student group 4-pH 7 | Student group 5-pH 8 | Student group 5-pH 8 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; Required practical activity 5: investigate the effect of pH on the rate of reaction of amylase enzyme. Students should use a continuous sampling technique to determine the time taken to completely digest a starch solution at a range of pH values. Iodine reagent is to be used to test for starch every 30 seconds. Temperature must be controlled by use of a water bath or electric heater. AT skills covered by this practical activity: AT 1, 2, 5 and 8. This practical activity also provides opportunities to develop WS and MS. Details of all skills are given in Key opportunities for skills development.

Food tests (RP 4-separate science). This practical was completed in one lesson, students were asked to construct a graph from their data for homework. How did i deliver this practical? Groups of 3, each group needs a test tube rack, 3 x test tubes and 1 x boiling tube. Goggles must be worn throughout the practical. Circus activity-students visited a station to complete a food test (avoids too many students doing the same test or taking all the reagents). Instead of using a hot water bath for the simple sugars test i lit a bunsen burner and allowed students to heat their solution in a boiling tube, holding it at a slant near the flame using tongs. Students really enjoyed this and the colour change is very sudden. Only one bunsen burner needs to be on for this and can be manned by the teacher to prevent misuse. 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; Required practical 4-qualitative reagents to test for a range of carbohydrates, lipids and proteins.

For further enquiries please email paperfriendlyresources@gmail.com AQA spec link: 4.7.1.2 The many hydrocarbons in crude oil may be separated into fractions, each of which contains molecules with a similar number of carbon atoms, by fractional distillation. The fractions can be processed to produce fuels and feedstock for the petrochemical industry. Many of the fuels on which we depend for our modern lifestyle, such as petrol, diesel oil, kerosene, heavy fuel oil and liquefied petroleum gases, are produced from crude oil. Many useful materials on which modern life depends are produced by the petrochemical industry, such as solvents, lubricants, polymers, detergents. The vast array of natural and synthetic carbon compounds occur due to the ability of carbon atoms to form families of similar compounds. Students should be able to explain how fractional distillation works in terms of evaporation and condensation. Knowledge of the names of other specific fractions or fuels is not required.

Human reproduction lesson created in accordance to the NEW AQA Specification (9-1) for my separates class (Year 10-KS4). Includes: slide animations, embedded videos and practice questions with answers on slides. This resource is suitable for combined science students. May needed to be edited for foundation students. AQA spec link: 5.3.4 Relevant chapter: B11 Hormonal coordination. AQA Biology third edition textbook-Page 168-169. Specification requires students to know the following; Students should be able to describe the roles of hormones in human reproduction, including the menstrual cycle. During puberty reproductive hormones cause secondary sex characteristics to develop. Oestrogen is the main female reproductive hormone produced in the ovary. At puberty eggs begin to mature and one is released approximately every 28 days. This is called ovulation. Testosterone is the main male reproductive hormone produced by the testes and it stimulates sperm production. Several hormones are involved in the menstrual cycle of a woman. • Follicle stimulating hormone (FSH) causes maturation of an egg in the ovary. • Luteinising hormone (LH) stimulates the release of the egg. • Oestrogen and progesterone are involved in maintaining the uterus lining.
