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 detailed lesson explains how the process of transcription results in the production of the single-stranded nucleic acid, mRNA. Both the detailed PowerPoint and accompanying resource have been designed to specifically cover the third part of point 2.1.3 of the OCR A-level Biology A specification but also provides important information that students can use when being introduced to splicing and gene expression in module 6.
The lesson begins by challenging the students to recognise that most of the nuclear DNA in eukaryotes does not code for polypeptides. This allows the promoter region and terminator region to be introduced, along with the structural gene. Through the use of an engaging quiz competition, students will learn that the strand of DNA involved in transcription is known as the template strand and the other strand is the coding strand. Links to previous lessons on DNA and RNA structure are made throughout and students are continuously challenged on their prior knowledge as well as they current understanding of the lesson topic. Moving forwards, the actual process of transcription is covered in a 7 step bullet point description where the students are asked to complete each passage using the information previously provided. So that they are prepared for module 6, students will learn that the RNA strand formed at the end of transcription in eukaryotes is a primary transcript called pre-mRNA and then the details of splicing are explained. An exam-style question is used to check on their understanding before the final task of the lesson looks at the journey of mRNA to the ribosome for the next stage of translation.
This lesson has been written to challenge all abilities whilst ensuring that the most important details are fully explained.
This fully-resourced lesson describes how DNA is replicated during interphase of the cell cycle and explains why it is known as semi-conservative replication. Both the detailed PowerPoint and accompanying resources have been designed to cover the details of point 2.1.3 (e) of the OCR A-level Biology A specification and the occurrence of spontaneous mutations is also discussed in the latter part of the lesson.
As detailed in the specification, the focus of this lesson is the role of the enzymes DNA helicase and polymerase and students are also introduced to DNA ligase to enable them to understand how this enzyme functions to join the nucleic acid fragments. Time is taken to explain key details such as the assembly of strands in the 5’-to-3’ direction so that the continuous manner in which the leading strand is synthesised can be compared against that of the lagging strand. The students are constantly challenged to make links to previous topics such as DNA structure, phosphorylated nucleotides and hydrolysis reactions through a range of exam questions and answers are displayed so any misconceptions are quickly addressed. The final part of the lesson focuses on the occurrence of mistakes by DNA polymerase and also on the quantity of DNA in the cell following replication so that future links can be made to the cell cycle (as covered in module 2.1.6)
This detailed lesson describes the role of the mRNA, tRNA, rRNA and amino acids during the second stage of protein synthesis - translation. Both the PowerPoint and accompanying resources have been designed to cover the second part of point 2.1.3 (g) of the OCR A-level Biology A specification and continually links back to the previous lessons in this module on the structure of DNA and RNA and the genetic code
Translation is a topic which is often poorly understood and so this lesson has been written to enable the students to understand how to answer the different types of questions by knowing and including the key details of the structures involved. The lesson begins by challenging the students to consider why it is so important that the amino acids are assembled in the correct order during the formation of the chain. Moving forwards, a quick quiz round called “LOST IN TRANSLATION” is used to check on their prior knowledge of the mRNA strand, the tRNA molecules, the genetic code and the ribosomes. The next task involves a very detailed description of translation that has been divided into 14 statements which the students have to put into the correct order. By giving them a passage that consists of this considerable detail, they can pick out the important parts to use in the next task where they have to answer shorter questions worth between 3 and 4 marks. These types of questions are common in the assessments and by building up through the lesson, their confidence to answer this type should increase. The final two tasks of the lesson involve another quiz, where the teams compete to transcribe and translate in the quickest time before using all that they have absorbed to answer some questions which involve the genetic code and the mRNA codon table
This lesson focuses on the structure of RNA and specifically the similarities and differences between this nucleic acid and DNA so that students are prepared for the upcoming lessons on transcription and translation. The engaging and detailed PowerPoint and accompanying resource have been designed to cover part 1 of point 2.1.3 (g) of the OCR A-level Biology A specification which states that students should be able to describe the structure of molecules of messenger RNA, transfer RNA and ribosomal RNA. Students were introduced to nucleotides and the detailed structure of DNA in previous lessons, 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 by reminding students that RNA is a member of the family of nucleic acids and therefore has a number of structural features that are commonly shared with 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 fully-resourced lesson looks at the effects of nervous mechanisms on the heart rate. The engaging and detailed PowerPoint and accompanying resources have been designed to cover the part of point 5.1.5 (k) of the OCR A-level Biology A specification which states that students should be able to demonstrate and apply their knowledge and understanding of the control of the heart rate by the cardiovascular centre in the medulla oblongata
This lesson begins with a prior knowledge check where students have to identify and correct any errors in a passage about the conduction system of the heart. This allows the SAN to be recalled as this structure play an important role as the effector in this control system. Moving forwards, the three key parts of a control system are recalled as the next part of the lesson will specifically look at the range of sensory receptors, the coordination centre and the effector. Students are introduced to chemoreceptors and baroreceptors and time is taken to ensure that the understanding of the stimuli detected by these receptors is complete and that they recognise the result is the conduction of an impulse along a neurone to the brain. A quick quiz is used to introduce the medulla oblongata as the location of the cardiovascular centre. The communication between this centre and the SAN through the autonomic nervous system can be poorly understood so detailed explanations are provided and the sympathetic and parasympathetic divisions compared. The final task challenges the students to demonstrate and apply their understanding by writing a detailed description of the control and this task has been differentiated three ways to allow differing abilities to access the work
This is an engaging lesson that looks at the structures and actions of the two parts of the autonomic nervous system (ANS) and shows students where this particular system fits into the whole organisation of the nervous system.
The lesson begins by introducing the students to the idea that motor neurones are not simply somatic motor neurones but will actually be classified as autonomic motor neurones if they innervate the involuntary muscles. A range of tasks, progress checks and quick competitions are used during the lesson to engage the students in this topic and show them how it relates to other topics such as motor neurones and neurotransmitters. Key terminology is used throughout, such as ganglions, so that students can recognise and access the marks if an exam question on this topic arises.
This lesson has been written for A-level students
This is a fast-paced lesson that explores the structural differences (and similarities) between sensory and motor neurones. The lesson uses a range of tasks, progress checks and quick competitions to enable the students to recognise how these neurones differ in terms of the cell body, axon and dendron. Students will also understand that both neurones are myelinated which allows saltatory conduction to occur. Relay neurones are briefly discussed during the final section of the lesson.
This lesson has primarily been designed for A-level students but can be used with the content means that it is suitable for use with GCSE students too who are studying the nervous system.
This bundle of 5 lessons covers a lot of the content in Topic B6 (Plant structures and their functions) of the Edexcel GCSE Biology specification. The topics covered within these lessons include:

This is a fully-resourced lesson that looks at the functional and structural differences between the transport tissues in a plant, the xylem and phloem. The lesson includes an engaging lesson presentation (41 slides), which includes numerous student-led tasks, progress checks and quick competitions and two question worksheets, one of which is a differentiated version to enable those students who are finding this topic difficult to still be able to access the learning.
The lesson begins with the introduction of the two tissues as well as a brief introduction to the substances which they each carry. The next part of the lesson focuses on the xylem cells and the resulting xylem vessel, and key terms such as lignin are brought into the lesson so that students can understand how these cells are waterproofed, which causes them to decay and form hollow tubes. Having met a lot of information, students are challenged to act like an examiner to form a table based question to compare the xylem against the phloem where they have to come up with features which could be compared against. This table will form the backbone of the lesson and students will use it later in the lesson when they have to write summary passages about each of the tissues. Moving forwards, a quick competition is used to enable the students to meet the names of the cells that form the phloem tissue, the sieve tube elements and the companion cells. Students will see how they are involved in the functioning of the phloem and questions are posed which relate to other topics such as the involvement of mitochondria wherever active transport occurs. Progress checks like this are found at regular intervals throughout the lesson so that students can constantly assess their understanding.
This lesson has been designed for GCSE students. If you are looking to teach about these tissues but to a higher standard, you could use my uploaded alternative called Xylem and Phloem (A-level)

This fully-resourced lesson explains how gel electrophoresis is used to separate DNA fragments or proteins and explores its applications in genetic fingerprinting. The engaging and detailed PowerPoint and accompanying resources have been written to cover point 6.1.3 (e) of the OCR A-level Biology A specification
The steps of the genetic fingerprinting process is covered the whole lesson but the main focus is the use of gel electrophoresis within this process. Students will be introduced to STRs and will come to recognise their usefulness in human identification as a result of the variability between individuals. Moving forwards, the involvement of the PCR is discussed and students are challenged on their knowledge of this process as it was encountered in a previous lesson. A brief outline of the role of restriction enzymes is provided to support students when these key gene technology enzymes are met in more detail later in the module. The main section of the lesson focuses on the use of gel electrophoresis to separate DNA fragments (as well as proteins) and the key ideas of separation due to differences in base pair length or molecular mass are discussed and explained. As well as current understanding checks, an application question involving Huntington’s disease is used to challenge their ability to apply their knowledge of the process to an unfamiliar situation. The remainder of the lesson describes how the DNA is transferred to a membrane and hybridisation probes are used to create a pattern on the X-ray film.
Time has been taken to make continuous links to the previous lessons in module 6.1.3 as well as those from module 2.1.3 where DNA, RNA and protein synthesis were introduced.
