C10-Chemical analysis-Pure substances and mixtures lesson created in accordance to the NEW AQA Specification (9-1). Designed for a low ability year 11 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 interactive review task. If for any reason the video link does not work, a URL has also been included in the notes. AQA spec link: 5.8.1.1 and 5.8.1.2 In chemistry, a pure substance is a single element or compound, not mixed with any other substance. Pure elements and compounds melt and boil at specific temperatures. Melting point and boiling point data can be used to distinguish pure substances from mixtures. In everyday language, a pure substance can mean a substance that has had nothing added to it, so it is unadulterated and in its natural state, eg pure milk. Students should be able to use melting point and boiling point data to distinguish pure from impure substances. Many products are complex mixtures in which each chemical has a particular purpose. Formulations are made by mixing the components in carefully measured quantities to ensure that the product has the required properties. Formulations include fuels, cleaning agents, paints, medicines, alloys, fertilisers and foods. Students should be able to identify formulations given appropriate information. Students do not need to know the names of components in proprietary products.

The role of negative feedback lesson created in accordance to the NEW AQA Specification (9-1) for my separates class (Year 10-KS4). This content is for HIGHER TIER only. 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: 5.3.7 Relevant chapter: B11 Hormonal coordination. AQA Biology third edition textbook-Page 166-167. Specification requires students to know the following; Students should be able to explain the roles of thyroxine and adrenaline in the body. Adrenaline is produced by the adrenal glands in times of fear or stress. It increases the heart rate and boosts the delivery of oxygen and glucose to the brain and muscles, preparing the body for ‘flight or fight’. Thyroxine from the thyroid gland stimulates the basal metabolic rate. It plays an important role in growth and development. Thyroxine levels are controlled by negative feedback.

AQA spec link: 4.2.2.6 Relevant chapter: B7 Non-communicable diseases. 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.

Health and disease lesson 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 and practice questions with answers. This resource is suitable for separate science students. AQA spec link: 4.3.1.1 Relevant chapter: B5-Communicable diseases . AQA Biology third edition textbook-Page 76-77. *The new specification requires students to know the following; Students should be able to explain how diseases caused by viruses, bacteria, protists, and fungi are spread in animals and plants. Pathogens are microorganisms that cause infectious disease. Pathogens may be viruses, bacteria, protists, or fungi. They may infect animals and can be spread by direct contact, by water, or by air. Bacteria and viruses may reproduce rapidly inside the body. Bacteria may produce poisons (toxins) that damage tissues and make us feel ill. Viruses live and reproduce inside cells, causing cell damage.

The history of genetics lesson created in accordance to the NEW AQA Specification (9-1). Designed for a separates class. 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: 4.6.3.3 Relevant chapter: B15 Genetics and evolution. AQA Biology trilogy edition textbook-Page 234-235 Students are required to know the following; Students should be able to: • describe the development of our understanding of genetics including the work of Mendel • understand why the importance of Mendel’s discovery was not recognised until after his death. In the mid-19th century Gregor Mendel carried out breeding experiments on plants. One of his observations was that the inheritance of each characteristic is determined by ‘units’ that are passed on to descendants unchanged. In the late 19th century behaviour of chromosomes during cell division was observed. WS 1.1 Our current understanding of genetics has developed over time. In the early 20th century it was observed that chromosomes and Mendel’s ‘units’ behaved in similar ways. This led to the idea that the ‘units’, now called genes, were located on chromosomes. In the mid-20th century the structure of DNA was determined and the mechanism of gene function worked out. This scientific work by many scientists led to the gene theory being developed.

Accepting Darwin’s ideas lesson created in accordance to the NEW AQA Specification (9-1). Designed for a separates class. 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. **Please note the homework and markscheme from the lesson on theories of evolution (B15.2) has also been included in this resource. ** AQA spec link: 4.6.3.1 Relevant chapter: B15 Genetics and evolution. AQA Biology trilogy edition textbook-Page 238-239 Students are required to know the following; Darwin published his ideas in On the Origin of Species (1859). There was much controversy surrounding these revolutionary new ideas. The theory of evolution by natural selection was only gradually accepted because: • the theory challenged the idea that God made all the animals and plants that live on Earth • there was insufficient evidence at the time the theory was published to convince many scientists • the mechanism of inheritance and variation was not known until 50 years after the theory was published.

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.

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.

Germination Practical (RP 8). This practical was completed in 2 lessons. Students are required to collect data outside of lesson time. I’ve attached both lessons, mock data (lesson 2) and a sign in sheet so you can create your own groups and student rota. Good luck! Lesson 1: Demo provided, students set up their practical, three conditions were created; full light-by windowsill, partial light-underneath windowsill and darkness-cupboard. The remainder of the lesson was spent discussing how to collect data, the student rota was explained. Students also used this time to assign roles to one another. Opportunity to collect data at break/lunch over 7 days (excluding weekends). Lesson 2: Interpreting data, working out averages, plotting graph, biological drawings. Conclusion and evaluation of practical was given as homework. Overall, this practical was very easy to set up but very fiddly to organise. Students need to take active approach as this practical needs to be done over 7 consecutive days, ownership to students. Mustard seeds were quick to germinate but were very poor at demonstrating phototropism. I would probably use coriander seeds next time. Also in the dark condition shoots grew very long, this confused students as light was absent (due to Etiolation), to complex for GCSE students to comprehend. Spec ref: 5.4.1 Required practical: Investigate the effect of light or gravity on the growth of newly germinated seedlings. Record results as both length measurements and as careful, labelled biological drawings to show the effects.

Gene expression and mutation lesson created in accordance to the NEW AQA Specification (9-1). NB: BIOLOGY ONLY-HT. 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. AQA spec link: 6.1.5 Relevant chapter: B13 Genetics and reproduction. AQA Biology third edition textbook-Page 206-207. Specification requires students to know the following; (HT only) Mutations occur continuously. Most do not alter the protein, or only alter it slightly so that its appearance or function is not changed. (HT only) A few mutations code for an altered protein with a different shape. An enzyme may no longer fit the substrate binding site or a structural protein may lose its strength. (HT only) Not all parts of DNA code for proteins. Non-coding parts of DNA can switch genes on and off, so variations in these areas of DNA may affect how genes are expressed.
