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.
A Science teacher by trade, I've also been known to be found teaching Maths and PE!

This bundle of 4 lessons covers all of the content in the sub-topic B1.3 (Transport in cells) of the AQA Trilogy GCSE Combined Science specification. The topics covered within these lessons include:
Diffusion
Examples of diffusion in organisms
Factors that affect the rate of diffusion
SA:V ratio and the need for exchange surfaces
Osmosis
Active transport
All of these lesson presentations and accompanying resources are detailed and engaging and contain regular progress checks to allow the students to constantly assess their understanding.
This bundle of 3 lessons looks at the different methods by which molecules move across cell membranes. These lessons have been written for GCSE aged students, but could be used with younger students who are studying this topic and want to be challenged. Students will understand how the passive processes of diffusion and osmosis move molecules with the concentration gradient whilst active transport moves them against the gradient and therefore requires energy in the form of ATP. Time is taken to go through the factors that increase the rate of diffusion as well as relating this to the living organism with examples in the body.
This is a detailed and engaging lesson that looks at how molecules move between areas of differing concentrations by diffusion and then explores how this occurs across cell membranes and focuses on the alveoli.
The lesson begins by using a step by step format to write the definition for diffusion so that key terms such as concentration gradient are understood. Students will be introduced to this as a passive process so that they can understand how active transport differs when this is met in another lesson. Progress checks are written into the lesson at regular intervals so that students can assess their understanding against a displayed answer. Moving forwards, the lesson focuses on diffusion across cell membranes and uses the example of the exchange surface of the alveoli and blood capillaries to explore the different features which act to increase the rate of diffusion. The final part of the lesson briefly looks at how the villi in the small intestine increase the rate of diffusion.
This lesson has been written for GCSE aged students. If you’re looking for a lesson on this topic but for older students, then my alternative upload “Simple diffusion” will be more suitable
This bundle of 4 lesson presentations and associated resources cover a lot of the mathematical skills that can be tested in Science. Since the move to the new GCSE specifications, the mathematical element has increased significantly and these lessons act to guide students through these skills. Students are shown how to convert between units, rearrange to change the subject of the formula and to use significant figures and standard form.
This bundle of 5 lessons covers the majority of the content in Topic B3 (Infection and response) of the AQA Trilogy GCSE Combined Science specification. The topics and specification points covered within these lessons include:

All of these lesson presentations and accompanying resources are detailed and engaging and contain regular progress checks to allow the students to constantly assess their understanding.
This is an engaging lesson that looks at how vaccinations are used in medicine and considers how the introduction of these preventative measures has reduced the incidence of disease.
The lesson begins by introducing vaccinations as the deliberate exposure to antigenic material and then reminds students of the meaning of the term, antigen, so that they understand how this will elicit the desired immune response. Lots of opportunities for discussion have been written into the lesson so that key points such as how the vaccination is altered so that isn’t harmful and how memory cells work can be discussed amongst students before being clarified by the teacher and the lesson content. Moving forwards, students will be given some figures on child mortality rate in 1900 and 2000. They are shown how to manipulate this data in order to work out the percentage change. Students are then challenged to use these skills when comparing the children that were vaccinated for whooping cough in 1968 and 1995 and to make a link between vaccinations and mortality rates. These mathematical skills are being tested more and more in Biology so this guidance will help students to understand how to manipulate data when required. Progress checks have been written into the lesson at regular intervals so that students can constantly assess their understanding.
This lesson has been designed for GCSE aged students. If you’re looking for a lesson on this same topic but for older students at A-level, then my upload “Vaccinations (A-level)” will be more suitable

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.
