A Science teacher by trade, I've also been known to be found teaching Maths and PE! However, strange as it may seem, my real love is designing resources that can be used by other teachers to maximise the experience of the students. I am constantly thinking of new ways to engage a student with a topic and try to implement that in the design of the lessons.

This fully-resourced lesson looks at the structure of genes and explores their role as a base sequence on DNA that codes for the amino acid sequence of a polypeptide. Both the PowerPoint and accompanying resource have been designed to cover point 6.2 (a) of the CIE International A-level Biology specification which states that students should understand how a gene codes for a polypeptide.
The lesson begins with a prior knowledge check as the students have to recognise the key term chromosome from a description involving DNA and histones. This allows genes, as sections of a chromosome, to be introduced and the first of a number of quiz rounds is then used to get the students to meet the term locus so that they can understand how each gene has a specific location on a chromosome. Whenever possible, opportunities are taken to make links to the other parts of the CIE specification and this is utilised here as students are reminded that alternative versions of a gene (alleles) can be found at the locus. Moving forwards, students will learn that 3 DNA bases is a triplet and that each triplet codes for a specific amino acid. At this point, the genetic code is introduced and students are challenged to explain how the code contains 64 different triplets. By comparing this number against the number of different amino acids in proteins, students will see how each amino acid is encoded for by more than one triplet and how this explains the degenerate nature of the genetic code which forms a link to an upcoming lesson on gene mutations.
This lesson focuses on the structure of RNA and specifically the similarities and differences between this nucleic acid and DNA. The engaging and detailed PowerPoint and accompanying resource have been designed to cover the second part of point 6.1 (b) of the CIE International A-level Biology specification which states that students should be able to describe the structure of this nucleic acid. Students were introduced to the detailed structure of a nucleotide and DNA in previous lessons, so this lesson is written to tie in with those and continuously challenge prior knowledge as well as the understanding of the current topic.
The lesson begins with the introduction of RNA as a member of the family of nucleic acids and this enables students to recognise that this polynuclotide shares a number of structural features that were previously seen in DNA. A quiz round called “A FAMILY AFFAIR” is used to challenge their knowledge of DNA to recognise those features that are also found on RNA such as the chain of linked nucleotides, pentose sugars, nitrogenous bases and phosphodiester bonds. The next task pushes them to consider features that have not been mentioned and therefore are differences as they answer a structured exam-style question on how RNA differs from DNA. Students will learn that RNA is shorter than DNA and this leads into the final part of the lesson where mRNA and tRNA are introduced and again they are challenged to use the new information explain the difference in size. Brief details of transcription and then translation are provided so that students are prepared for the upcoming lessons on protein synthesis
This lesson looks at the detailed structure of DNA and builds on the knowledge from topic 1 to explain how this nucleic acid differs in the nucleus, mitochondria and chloroplasts of eukaryotic cells and in prokaryotic cells. Both the engaging PowerPoint and accompanying resources have been designed to cover the first part of point 6.1 (b) of the CIE International A-level Biology specification.
As well as focusing on the differences between the DNA found in these two types of cells which includes the length, shape and association with histones, the various tasks will ensure that students are confident to describe how this double-stranded polynucleotide is held together by hydrogen and phosphodiester bonds. These tasks include exam-style questions which challenge the application of knowledge as well as a few quiz competitions to maintain engagement.
This lesson focuses on the structure of RNA and specifically the similarities and differences between this nucleic acid and DNA. The engaging and detailed PowerPoint and accompanying resource have been designed to cover part 1 of point 4.2 of the AQA A-level Biology specification which states that students should be able to describe the structure of molecules of messenger RNA and transfer RNA as well as understand the concept of a genome and proteome. Students were introduced to the detailed structure of DNA in previous lessons covering specification point 4.1, so this lesson is written to tie in with those and continuously challenge prior knowledge as well as understanding of the current topic.
The lesson begins with the introduction of the term genome and proteome and students are challenged to make the link between the genes in an organism and all of the proteins that can be produced by these sequence of bases. Moving forwards, students will learn that RNA is a member of the family of nucleic acids and therefore has a number of structural features that were previously seen in DNA. A quiz round called “A FAMILY AFFAIR” is used to challenge their knowledge of DNA to recognise those features that are also found on RNA such as the chain of linked nucleotides, pentose sugars, nitrogenous bases and phosphodiester bonds.

Both the PowerPoint and accompanying resource have been designed to cover the second part of point 4.1 of the AQA A-level Biology specification and has been written to specifically tie in with the previous lesson on DNA in prokaryotes and eukaryotes.

Again, an opportunity is taken to link to gene mutations. Finally, the students are told that most of the nuclear DNA in a eukaryote doesn’t code for a polypetptide and that even within a gene, there are coding and non-coding regions known as exons and introns respectively. The last section of the lesson uses a quiz round to check on all of the key terms which have been met in the two lessons on DNA, genes and chromosomes.
This lesson looks at the structure of the DNA that is found in the nucleus, mitochondria and chloroplasts of eukaryotic cells and in prokaryotic cells. Both the engaging PowerPoint and accompanying resources have been designed to cover the first part of point 4.1 of the AQA A-level Biology specification.
As students will already have some knowledge of this nucleic acid from GCSE and from the earlier A-level topics, the lesson has been written to build on this prior knowledge and then to add key detail. As well as focusing on the differences between the DNA found in these two types of cells which includes the length, shape and association with histones, the various tasks will ensure that students are confident to describe how this double-stranded polynucleotide is held together by hydrogen and phosphodiester bonds. These tasks include exam-style questions which challenge the application of knowledge as well as a few quiz competitions to maintain engagement.
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.

This lesson has been designed to tie in with the other 8 uploaded revision lessons which cover the content of the 8 topics on the AQA GCSE Physics specification
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 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.
