This lesson describes how to use and manipulate the magnification formula to calculate the magnification or the actual size in a range of units. The PowerPoint and accompanying resources have been designed to cover point 2.1.1 (e) of the OCR A-level Biology A specification and contains a number of quiz rounds as part of the competition that runs throughout all of the module 2.1.1 lessons
The students are likely to have met the magnification formula at GCSE so this lesson has been written to build on that knowledge and to support them with more difficult questions when they have to calculate actual size without directly being given the magnification. A step by step guide is used to walk the students through the methodology and useful tips are provided. Students could be asked to calculate the actual size in millimetres, micrometres, nanometres or picometres so time is taken to ensure that they can convert between one and another.

Maths in A-level Biology (OCR A-level Biology)
The mathematical element of the OCR A-level Biology A specification is substantial and every year, there are a large number of exam questions that require the application of a range of mathematical skills. Therefore, a clear understanding of how and when to apply these skills is closely related to success on this course and the following calculations are covered by the 9 lessons that are included in this bundle: * Using the chi-squared test to determine significance between the observed and expected results of a genetic cross * Using the Hardy Weinberg principle to calculate the frequency of an allele or a genotype in a population * Calculating the standard deviation to measure the spread of data * Using the Student's t-test to compare the means of two sets of data * Calculating the temperature coefficient * Calculating the proportion of polymorphic gene loci * Using and interpreting Simpson's index of diversity to calculate the biodiversity of a habitat * Using the Spearman's rank correlation coefficient to consider the relationship of the data * The use and manipulation of the magnification formula A revision lesson is also included in this bundle which acts as a fun and engaging revision of the range of calculations

Cell structure & biological molecules (OCR A-level Biology A)
It's fair to say that cell structure and biological molecules are two of the most important topics in the OCR A-level Biology A course and all 19 lessons that are included in this bundle have been planned at length to cover the module 2.1.1 & 2.1.2 specification points in the detail required at this level. The lesson PowerPoints and their accompanying resources contain a wide range of tasks as well as regular checks to allow students to assess their understanding of the current content as well as prior knowledge checks to emphasise the importance of making links to topics in other modules. The following specification points in modules 2.1.1 (cell structure) and 2.1.2 (biological molecules) are covered by the lessons in this bundle: 2.1.1 * The use of microscopy to observe and investigate different types of cell and cell structure in a range of eukaryotic organisms * The use of the eyepiece graticule and stage micrometer * The use of staining in light microscopy * The use and manipulation of the magnification formula * The difference between magnification and resolution * The ultrastructure of eukaryotic cells and the functions of the different cellular components * The interrelationship between the organelles involved in the production and secretion of proteins * The importance of the cytoskeleton * The similarities and differences between the ultrastructure of prokaryotic and eukaryotic cells 2.1.2 * The properties and roles of water in living organisms * The concept of monomers and polymers and the importance of condensation and hydrolysis reactions * The chemical elements that make up biological molecules * The structure and properties of glucose and ribose * The synthesis and breakdown of a disaccharide and a polysaccharide by the formation and breakage of glycosidic bonds * The structure of starch, glycogen and cellulose molecules * The relationship between the structure, function and roles of triglycerides, phospholipids and cholesterol in living organisms * The general structure of an amino acid * The synthesis and breakdown of dipeptides and polypeptides * The levels of protein structure * The structure and function of globular proteins * The properties and functions of fibrous proteins * The key inorganic ions involved in biological processes * The chemical tests for proteins, reducing and non-reducing sugars, starch and lipids If you would like to sample the quality of the lessons included in this bundle, then download the following lessons as they have been uploaded for free: * The use of microscopy * The importance of the cytoskeleton * Properties and roles of water * Glucose & ribose * General structure of an amino acid * Dipeptides, polypeptides and protein structure

Module 2.1.1: Cell structure (OCR A-level Biology A)
As cells are the building blocks of living organisms, and Biology is the study of life, it's fairly obvious that a clear understanding of cell structure is going to be critical for the success of an A-level student on the OCR A-level Biology A course. The 6 lessons included in this bundle are highly detailed and have been intricately planned to contain the detail needed at this level and to make links to topics in the other modules of the specification. The lesson PowerPoints and accompanying resources contain a wide range of tasks which will engage and motivate the students whilst covering the following specification points in module 2.1.1: * The use of microscopy to observe and investigate different types of cell and cell structure in a range of eukaryotic organisms * The use of the eyepiece graticule and stage micrometer * The use of staining in light microscopy * The use and manipulation of the magnification formula * The difference between resolution and magnification * The ultrastructure of eukaryotic cells and the functions of the different cellular components * The interrelationship between the organelles involved in the production and secretion of proteins * The importance of the cytoskeleton * The similarities and differences in the structure and ultrastructure of prokaryotic and eukaryotic cells If you would like to sample the quality of the lessons included in this bundle, then download "The use of microscopy" and "cytoskeleton" lessons as these have been uploaded for free
