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.

Stem cells (introduction) 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: 4.1.2.3 Relevant chapter: B2 Cell division.

NB: If you are unable to play videos a URL link can be found in the slide notes. AQA spec link: 4.6.2.4 Relevant chapter: B13 Variation and evolution. AQA Biology third edition textbook-Page 224-225. Students are required to know the following; Students should be able to describe genetic engineering as a process which involves modifying the genome of an organism by introducing a gene from another organism to give a desired characteristic. Plant crops have been genetically engineered to be resistant to diseases or to produce bigger better fruits. Bacterial cells have been genetically engineered to produce useful substances such as human insulin to treat diabetes. Students should be able to explain the potential benefits and risks of genetic engineering in agriculture and in medicine and that some people have objections. In genetic engineering, genes from the chromosomes of humans and other organisms can be ‘cut out’ and transferred to cells of other organisms. Crops that have had their genes modified in this way are called genetically modified (GM) crops. GM crops include ones that are resistant to insect attack or to herbicides. GM crops generally show increased yields. Concerns about GM crops include the effect on populations of wild flowers and insects. Some people feel the effects of eating GM crops on human health have not been fully explored. Modern medical research is exploring the possibility of genetic modification to overcome some inherited disorders. (HT) Students should be able to describe the main steps in the process of genetic engineering. In genetic engineering: • enzymes are used to isolate the required gene; this gene is inserted into a vector, usually a bacterial plasmid or a virus • the vector is used to insert the gene into the required cells • genes are transferred to the cells of animals, plants, or microorganisms at an early stage (egg or embryo) in their development so that they develop with desired characteristics.

AQA Biology Third edition textbook-Page 252-253 Students are required to know the following; As evidence of internal structures became more developed due to improvements in microscopes, and the understanding of biochemical processes progressed, new models of classification were proposed. Due to evidence available from chemical analysis there is now a ‘threedomain system’ developed by Carl Woese. In this system organisms are divided into: •archaea (primitive bacteria usually living in extreme environments) •bacteria (true bacteria) •eukaryota (which includes protists, fungi, plants and animals). WS 1.1 Understand how scientific methods and theories develop over time. Evolutionary trees are a method used by scientists to show how they believe organisms are related. They use current classification data for living organisms and fossil data for extinct organisms.

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.

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 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.

Dont’t know if you’ve felt the same but my year 11 students really struggled to grasp punnett squares through a couple of worked examples so I designed a booklet solely focused on punnett square PPQ’s with some very challenging questions. As always total marks /21, not too short or too long to take up an entire lesson. A marking grid has also been included. Contains a range of short and longer answer questions also requires students to interpret diagrams. This is a great piece of homework or mini class test, that can allow you to determine whether your students have understood the topic. I’ve attached the mark scheme separately as it’s a great self/peer-assessed activity (reduce the marking load).

I taught bacterial and viral diseases in one lesson so that my students could compare and contrast between the two types. Students enjoyed finding out information online. It also allowed students to access a wealth of information and prompted very interesting discussions. I would recommend booking an ICT suite, i Pads or laptops to make the most out of the independent activity. If computer access is limited the student textbook can also be used :) 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, worksheets (including support sheet) and answers have also been included within the slides. This resource is suitable for separate science students. If you have a low ability group or would like to incorporate exam questions, i would recommend splitting this lesson in two. AQA spec link: 4.3.1.2, 4.3.1.3 Relevant chapter: B5-Communicable diseases . AQA Biology third edition textbook-Page 84-87. *The new specification requires students to know the following; Explain how the spread of diseases can be reduced or prevented. Viral diseases Measles is a viral disease showing symptoms of fever and a red skin rash. Measles is a serious illness that can be fatal if complications arise. For this reason most young children are vaccinated against measles. The measles virus is spread by inhalation of droplets from sneezes and coughs. HIV initially causes a flu-like illness. Unless successfully controlled with antiretroviral drugs the virus attacks the body’s immune cells. Late stage HIV infection, or AIDS, occurs when the body’s immune system becomes so badly damaged it can no longer deal with other infections or cancers. HIV is spread by sexual contact or exchange of body fluids such as blood which occurs when drug users share needles. Tobacco mosaic virus (TMV) is a widespread plant pathogen affecting many species of plants including tomatoes. It gives a distinctive ‘mosaic’ pattern of discolouration on the leaves which affects the growth of the plant due to lack of photosynthesis . Bacterial diseases Salmonella food poisoning is spread by bacteria ingested in food, or on food prepared in unhygienic conditions. In the UK, poultry are vaccinated against. Salmonella to control the spread. Fever, abdominal cramps, vomiting, and diarrhoea are caused by the bacteria and the toxins they secrete. Gonorrhoea is a sexually transmitted disease (STD) with symptoms of a thick yellow or green discharge from the vagina or penis and pain on urinating. It is caused by a bacterium and was easily treated with the antibiotic penicillin until many resistant strains appeared. Gonorrhoea is spread by sexual contact. The spread can be controlled by treatment with antibiotics or the use of a barrier method of contraception such as a condom.

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.
