Complete PowerPoint presentation for a 2 hour lesson on biodiversity within communities for AQA A Level Biology. Includes calculating the index of diversity, impact of agriculture on biodiversity and conservation techniques. New content slides and accompanying activities in the ‘learning loop’ format. Covers specification points: Biodiversity can relate to a range of habitats, from a small local habitat to the Earth. Species richness is a measure of the number of different species in a community. An index of diversity describes the relationship between the number of species in a community and the number of individuals in each species. Calculation of an index of diversity (d) from the formula d = N (N − 1) /n (n − 1) where N = total number of organisms of all species and n = total number of organisms of each species. Farming techniques reduce biodiversity. The balance between conservation and farming.

Complete 2 hour lesson on interpreting phylogenetic trees and clarifying evolutionary relationships using DNA sequences, proteins amino acid sequences and immunological techniques.

Could be easily adapted to suit a different lesson length.

Complete PowerPoint presentation for a 2 hour lesson on genetic diversity and adaptation for AQA A Level Biology. Includes natural selection, directional selection and stabilising selection. New content slides and accompanying activities in the ‘learning loop’ format. Covers specification points: Genetic diversity as the number of different alleles of genes in a population. Genetic diversity is a factor enabling natural selection to occur. The principles of natural selection in the evolution of populations. Random mutation can result in new alleles of a gene. Many mutations are harmful but, in certain environments, the new allele of a gene might benefit its possessor, leading to increased reproductive success. The advantageous allele is inherited by members of the next generation. As a result, over many generations, the new allele increases in frequency in the population. Directional selection, exemplified by antibiotic resistance in bacteria, and stabilising selection, exemplified by human birth weights. Natural selection results in species that are better adapted to their environment. These adaptations may be anatomical, physiological or behavioural.

PowerPoint presentation on microscopy - using light microscopes and comparing light and electron microscopes for AQA GCSE Biology. Full lesson using the learning loop format. Learning Objectives:  Prepare slides of plant and animal cells and describe the procedure. Correctly use a microscope to observe cells under different magnifications. Describe the differences in magnification and resolution of light and electron microscopes. Explain how electron microscopy has increased understanding of organelles. Calculate the magnification of a light microscope. Carry out calculations using the formula: real size = image size/magnification Rearrange the equation to calculate image size or magnification. Convert values for the units: cm, mm, µm and nm.

PowerPoint for complete lesson on osmosis and active transport for AQA A Level Biology 3.2.3 Transport across cell membranes • osmosis (explained in terms of water potential) • active transport (involving the role of carrier proteins and the importance of the hydrolysis of ATP) • co-transport (illustrated by the absorption of sodium ions and glucose by cells lining the mammalian ileum).

PowerPoint for full lesson on infertility for AQA GCSE Biology/trilogy. Covers fertility drugs, IVF and disadvantages/ethical issues. Covers: 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

A science placemat to print in A3 and laminate. Stick a few down on tables or around the edge of the room so pupils can use them as a self-help resource. Includes naming common equipment, units, drawing graphs, designing experiment and other core skills for science at KS3/4. Placemat is in Word format so feel free to edit it in any way you wish to suit your classes needs. NOTE: check format before printing- format may be skewed if opening in different versions of word so check before printing, you may have to rearrange things slightly.

PowerPoint presentation on species, courtship behaviour and classification - used for AQA A Level Biology (2 hour lesson) but could be easily adapted. Topic 3.4.5 Specification points covered: Two organisms belong to the same species if they are able to produce fertile offspring. Courtship behaviour as a necessary precursor to successful mating. The role of courtship in species recognition. A phylogenetic classification system attempts to arrange species into groups based on their evolutionary origins and relationships. It uses a hierarchy in which smaller groups are placed within larger groups, with no overlap between groups. Each group is called a taxon (plural taxa). One hierarchy comprises the taxa: domain, kingdom, phylum, class, order, family, genus and species. Each species is universally identified by a binomial consisting of the name of its genus and species, eg, Homo sapiens.

Lesson on proteins for AQA A Level Biology. Some slides taken from other free PowerPoints available on TES - thank you for sharing! Covering: Amino acids are the monomers from which proteins are made. The general structure of an amino acid. The twenty amino acids that are common in all organisms differ only in their side group. A condensation reaction between two amino acids forms a peptide bond. • Dipeptides are formed by the condensation of two amino acids. • Polypeptides are formed by the condensation of many amino acids. A functional protein may contain one or more polypeptides. The role of hydrogen bonds, ionic bonds and disulfide bridges in the structure of proteins. Proteins have a variety of functions within all living organisms. The relationship between primary, secondary, tertiary and quaternary structure, and protein function. The biuret test for proteins.

Powerpoint presentation on the light-dependent reaction of photosynthesis for AQA A-level Biology. Full lesson (‘learning loop’ style lesson) includes starter, objectives, summary content slides, practise question and mark scheme and evaluation. Covers specification points: The light-dependent reaction in such detail as to show that: • chlorophyll absorbs light, leading to photoionisation of chlorophyll • some of the energy from electrons released during photoionisation is conserved in the production of ATP and reduced NADP • the production of ATP involves electron transfer associated with the transfer of electrons down the electron transfer chain and passage of protons across chloroplast membranes and is catalysed by ATP synthase embedded in these membranes (chemiosomotic theory) • photolysis of water produces protons, electrons and oxygen.

A full lesson PowerPoint for AQA A Level Biology on the structure of cell membranes. 3.2.3 Transport across cell membranes The basic structure of all cell membranes, including cell-surface membranes and the membranes around the cell organelles of eukaryotes, is the same. The arrangement and any movement of phospholipids, proteins, glycoproteins and glycolipids in the fluid-mosaic model of membrane structure. Cholesterol may also be present in cell membranes where it restricts the movement of other molecules making up the membrane.

PowerPoint for a complete lesson on transport across membranes, focussing on simple and facilitated diffusion for AQA A Level Biology. 3.2.3 Transport across cell membranes Movement across membranes occurs by: • simple diffusion (involving limitations imposed by the nature of the phospholipid bilayer) • facilitated diffusion (involving the roles of carrier proteins and channel proteins)
