This engaging lesson covers the biological classification of a species, phylogenetic classification and the use of the binomial naming system. The PowerPoint and accompanying resources have been designed to cover point 4.5 of the AQA A-level Biology specification which is titled species and taxonomy. The lesson begins by looking at the meaning of a population in Biology so that the term species can be introduced. A hinny, which is the hybrid offspring of a horse and a donkey, is used to explain how these two organisms must be members of different species because they are unable to produce fertile offspring. Although the art of courting might be lost on humans in the modern world, the marabou stork is used as an example to show how courtship behaviour is an essential precursor to successful mating in most organisms. Students are encouraged to discuss other examples of courtship behaviour, such as the release of pheromones and birdsong, so that their knowledge and understanding is broad. Moving forwards, students will learn that species is the lowest taxon in the modern-day classification hierarchy. A quiz runs throughout the lesson and this particular round will engage the students whilst they learn the names of the other 7 taxa and the horse and the donkey from the earlier example are used to complete the hierarchy. Students will understand that the binomial naming system was introduced by Carl Linnaeus to provide a universal name for each species and they will be challenged to apply their knowledge by completing a hierarchy for a modern-day human, by spotting the correct name for an unfamiliar organism and finally by suggesting advantages of this system. The final part of the lesson briefly looks at how advances in genome sequencing and the comparison of common biological molecules has allowed the relationships between organisms to be clarified. This is a detailed lesson and it is estimated that it will take around 2 hours of A-level teaching time to cover the content and therefore this specification point.

This revision lesson has been designed to challenge the students on their use of a range of mathematical skills that could be assessed on the six OCR Gateway A GCSE Combined Science papers. The mathematical element of the GCSE Combined Science course has increased significantly since the specification change and therefore success in those questions which involve the use of maths can prove to be the difference between one grade and another or possibly even more. The engaging PowerPoint and accompanying resources contain a wide range of activities that include exam-style questions with displayed mark schemes and explanations so that students can assess their progress. Other activities include differentiated tasks, class discussion points and quick quiz competitions such as “It doesn’t HURT to CONVERT”, “YOU DO THE MATH” and “FILL THE VOID”. The following mathematical skills (in a scientific context) are covered in this lesson: The use of Avogadro’s constant Rearranging the formula of an equation Calculating the amount in moles using mass and relative formula mass Calculating the relative formula mass for formulae with brackets Using the Periodic Table to calculate the number of sub-atomic particles in atoms Changes to electrons in ions Balancing chemical symbol equations Empirical formula Converting between units Calculating concentration in grams per dm cubed and volumes of solutions Calculating size using the magnification equation Using the mean to estimate the population of a sessile species Calculating percentages to prove the importance of biodiversity Calculating percentage change The BMI equation Calculating the acceleration from a velocity-time graph Recalling and applying the Physics equations Understanding prefixes that determine size Leaving answers to significant figures and using standard form Helpful hints and step-by-step guides are used throughout the lesson to support the students and some of the worksheets are differentiated two ways to provide extra assistance. Due to the detail of this lesson, it is estimated that it will take in excess of 3 hours of GCSE teaching time to cover the tasks and for this reason it can be used over a number of lessons as well as during different times of the year for revision

This detailed lesson outlines the characteristics features of the kingdoms Protoctista, Fungi, Plantae and Animalia. The engaging PowerPoint and accompanying resources have been designed to cover point 18.2 [c] of the CIE International A-level Biology specification which states that students should be able to describe the features of these four eukaryotic kingdoms. This lesson begins with a knowledge recall as students have to recognise that prior to 1990, kingdom was the highest taxa in the classification hierarchy. Moving forwards, they will recall the names of the five kingdoms and immediately be challenged to split them so that the prokaryotae kingdom is left on its own. The features of this kingdom are given so that the lesson can focus on the four eukaryotic kingdoms. Students are constantly challenged on their understanding of the current topic as well as that of earlier topics, as demonstrated by a differentiated task about the structure and function of cellulose which was covered in topic 2. This task is found in the section of the lesson where the main constituent of the wall can be used to distinguish between plantae, fungi and prokaryotae. Quick quiz competitions, such as SAY WHAT YOU SEE are used to introduce key terms in a fun and memorable way. The final part of the lesson looks at the protoctista kingdom and students will come to understand how these organisms tend to share a lot of animal or plant-like features.

This lesson describes the classification of species into the taxonomic hierarchy and cover point 18.2 (a) of the CIE A-level Biology specification. The engaging PowerPoint and accompanying resources have been designed to show students how the domain, kingdom, phylum, class, order, family, genus and species are used in modern-day classification. The lesson begins by with a knowledge recall as students have to use the provided information about a mule to explain why a horse and donkey are considered to be members of different species. Moving forwards, students will learn that species is the lowest taxon in the modern-day classification hierarchy. The first of a number of rounds of a competition is used to engage the students whilst they learn the names of the 7 other taxa and the horse and the donkey from the earlier example are used to complete the hierarchy. Students are told that a binomial naming system is used in Biology to provide a universal name for each species and the final task of the lesson challenges them to apply their knowledge by completing a hierarchy for a modern-day human, by spotting the correct name for an unfamiliar organism

This detailed lesson explains how observable features at a microscopic level can be used to classify living organisms into one of the five kingdoms. The engaging PowerPoint and accompanying resources have been designed to cover point 4.2.2 © (i) of the OCR A-level Biology A specification which states that students should be able to demonstrate and apply an understanding of the features of the animalia, plantae, fungi, protoctista and prokaryotae kingdoms. This lesson begins with a knowledge recall as students have to recognise that prior to 1990, kingdom was the highest taxa in the classification hierarchy. Moving forwards, they will recall the names of the five kingdoms and immediately be challenged to split them so that the prokaryotae kingdom is left on its own. An opportunity is taken at this point to check on their prior knowledge of the structure of a bacterial cell from module 2.1.1. These prior knowledge checks are found throughout the lesson (along with current understanding checks) as students are also tested on their knowledge of the structure and function of cellulose. This is found in the section of the lesson where the main constituent of the wall can be used to distinguish between plantae, fungi and prokaryotae. Quick quiz competitions, such as YOU DO THE MATH and SAY WHAT YOU SEE are used to introduce key values and words in a fun and memorable way. The final part of the lesson looks at the protoctista kingdom and students will come to understand how these organisms tend to share a lot of animal or plant-like features. Both of the accompanying resources have been differentiated to allow students of differing abilities to access the work and this lesson has been written to tie in with the previously uploaded lesson on taxonomic hierarchy and the binomial naming system (4.2.2 a & b).

This lesson covers the biological classification of a species, taxonomic hierarchy and the binomial system of naming species. The engaging PowerPoint and accompanying resources have been designed to cover points 4.2.2 (a) & (b) of the OCR A-level Biology A specification which states that students should be able to demonstrate and apply an understanding of these three topics. The lesson begins by looking at the meaning of the term population in Biology so that the term species can be introduced. A hinny, which is the hybrid offspring of a horse and a donkey, is used to explain how these two organisms must be members of different species because they are unable to produce fertile offspring.
