***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.

Competition in plants 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: 4.7.1.1 Relevant chapter: B16 Adaptations, interdependence and competitions. AQA Biology third edition textbook-Page 266-267 Students are required to know the following; Plants in a community or habitat often compete with each other for light and space, and for water and mineral ions from the soil. Animals often compete with each other for food, mates and territory. Within a community each species depends on other species for food, shelter, pollination, seed dispersal etc. If one species is removed it can affect the whole community. This is called interdependence. A stable community is one where all the species and environmental factors are in balance so that population sizes remain fairly constant. Students should be able to extract and interpret information from charts, graphs, and tables relating to the interaction of organisms within a community.

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.

Common problems of the eye lesson created in accordance to the NEW AQA Specification (9-1). Designed for a higher ability, separate science class, although content can be adjusted to suit any ability. Includes powerpoint timers, slide animations, embedded video’s, homework worksheet, markscheme and mini review. NB: If you are unable to play embedded videos please view slide notes for link. THIS LESSON IS FOR BIOLOGY ONLY AQA spec link: 4.5.2.3 Relevant chapter: B10 The human nervous system. AQA Biology Third edition textbook-Page 156-157 Students are required to know the following; Students should be able to relate the structures of the eye to their functions. This includes: • accommodation to focus on near or distant objects Accommodation is the process of changing the shape of the lens to focus on near or distant objects. To focus on a near object: • the ciliary muscles contract • the suspensory ligaments loosen • the lens is then thicker and refracts light rays strongly. To focus on a distant object: • the ciliary muscles relax • the suspensory ligaments are pulled tight • the lens is then pulled thin and only slightly refracts light rays. Two common defects of the eyes are myopia (short sightedness) and hyperopia (long sightedness) in which rays of light do not focus on the retina. • Generally these defects are treated with spectacle lenses which refract the light rays so that they do focus on the retina. • New technologies now include hard and soft contact lenses, laser surgery to change the shape of the cornea, and a replacement lens in the eye. Students should be able to interpret ray diagrams, showing these two common defects of the eye and demonstrate how spectacle lenses correct them.

The brain lesson created in accordance to the NEW AQA Specification (9-1). Designed for a higher ability, separate science class, although content can be adjusted to suit any ability. Includes powerpoint timers, slide animations, embedded video’s, worksheet and mini review. NB: If you are unable to play embedded videos please view slide notes for link. THIS LESSON IS FOR BIOLOGY ONLY AQA spec link: 4.5.2.2 Relevant chapter: B10 The human nervous system. AQA Biology Third edition textbook-Page 152-153 Students are required to know the following; The brain controls complex behaviour. It is made of billions of interconnected neurones and has different regions that carry out different functions. Students should be able to identify the cerebral cortex, cerebellum and medulla on a diagram of the brain, and describe their functions. (HT only) Students should be able to explain some of the difficulties of investigating brain function and treating brain damage and disease. (HT only) Neuroscientists have been able to map the regions of the brain to particular functions by studying patients with brain damage, electrically stimulating different parts of the brain and using MRI scanning techniques. The complexity and delicacy of the brain makes investigating and treating brain disorders very difficult.

Theories of evolution 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: 4.6.3.1 Relevant chapter: B15 Genetics and evolution. AQA Biology trilogy edition textbook-Page 236-237 Students are required to know the following; Charles Darwin, largely as a result of observations on a round the world expedition, linked to developing knowledge of geology and fossils, proposed the theory of natural selection: • Individual organisms within a particular species show a wide range of variation for a characteristic. • Individuals with characteristics most suited to the environment are more likely to survive to breed successfully. • The characteristics that have enabled these individuals to survive are then passed on to the next generation. Other theories, including that of Jean-Baptiste Lamarck, are based mainly on the idea that changes that occur in an organism during its lifetime can be inherited. We now know that in the vast majority of cases this type of inheritance cannot occur. A study of creationism is not required.

NB: This is a BIOLOGY (SEPARATES) ONLY lesson Plant defence responses lesson created in accordance to the NEW AQA Specification (9-1). Includes: slide animations, embedded videos, differentiated questions, answers have also been included within the slides. This resource is NOT suitable for combined science students. AQA spec link: 4.3.3.2 Relevant chapter: B5-Communicable diseases . AQA Biology third edition textbook-Page 94-95. Students should be able to describe physical and chemical plant defence responses. Physical defence responses to resist invasion of microorganisms: • Cellulose cell walls. • Tough waxy cuticle on leaves. • Layers of dead cells around stems (bark on trees) which fall off. Chemical plant defence responses: • Antibacterial chemicals. • Poisons to deter herbivores. Mechanical adaptations: • Thorns and hairs deter animals. • Leaves which droop or curl when touched. • Mimicry to trick animals.

DNA structure and protein synthesis lessons created in accordance to the NEW AQA Specification (9-1). NB: BIOLOGY ONLY. I taught this topic in two lessons as it's a topic that's a difficult concept and can be taught effectively as opposed to being rushed. This resource is 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, worksheets and an interactive quiz. AQA spec link: 6.1.5 Relevant chapter: B13 Genetics and reproduction. AQA Biology third edition textbook-Page 204-205. Students should be able to describe DNA as a polymer made from four different nucleotides. Each nucleotide consists of a common sugar and phosphate group with one of four different bases attached to the sugar. DNA contains four bases, A, C, G and T. A sequence of three bases is the code for a particular amino acid. The order of bases controls the order in which amino acids are assembled to produce a particular protein. The long strands of DNA consist of alternating sugar and phosphate sections. Attached to each sugar is one of the four bases. The DNA polymer is made up of repeating nucleotide units. (HT only) Students should be able to: •• recall a simple description of protein synthesis •• explain simply how the structure of DNA affects the protein made •• describe how genetic variants may influence phenotype: a) in coding DNA by altering the activity of a protein: and b) in non-coding DNA by altering how genes are expressed. (HT only) In the complementary strands a C is always linked to a G on the opposite strand and a T to an A. (HT only) Students are not expected to know or understand the structure of mRNA, tRNA, or the detailed structure of amino acids or proteins. (HT only) Students should be able to explain how a change in DNA structure may result in a change in the protein synthesised by a gene. (HT only) Proteins are synthesised on ribosomes, according to atemplate. Carrier molecules bring specific amino acids to add to the growing protein chain in the correct order. (HT only) When the protein chain is complete it folds up to form a unique shape. This unique shape enables the proteins to do their job as enzymes, hormones or forming structures in the body such as collagen.

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: B15 Genetics and evolution. AQA Biology Third edition textbook-Page 248-249 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.

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.

Evidence for evolution 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: 4.6.3.4 Relevant chapter: B15 Genetics and evolution. AQA Biology third edition textbook-Page 242-243 Students are required to know the following; Students should be able to describe the evidence for evolution including fossils and antibiotic resistance in bacteria. The theory of evolution by natural selection is now widely accepted. Evidence for Darwin’s theory is now available as it has been shown that characteristics are passed on to offspring in genes. There is further evidence in the fossil record and the knowledge of how resistance to antibiotics evolves in bacteria.

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. AQA spec link: 4.7.2.1 Relevant chapter: B16 Adaptations, interdependence and competition. AQA Biology third edition textbook-Page 262-263 In doing this practical students should cover these parts of the apparatus and techniques requirements. AT 1 – use appropriate apparatus to record length and area. AT 3 – use transect lines and quadrats to measure distribution of a species. AT 4 – safe and ethical use of organisms and response to a factor in the environment. AT 6 – application of appropriate sampling techniques to investigate the distribution and abundance of organisms in an ecosystem via direct use in the field. AT 8 – use of appropriate techniques in more complex contexts including continuous sampling in an investigation.
