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 detailed lesson presentation (37 slides) and associated worksheets that looks at the different pieces of evidence that scientists use to support evolution and discusses how these support the theory. The lesson begins by challenging students to decide which piece of evidence is the key piece in supporting evolution (fossils). Students will then have to arrange a number of statements to describe how a fossil is formed. Students are introduced to the fossil record and questions are used to check that they understand where the oldest fossils would be found. Moving forwards, students are given three pieces of evidence that would be observed in the fossil record and they are challenged to explain how each of these supports the theory of evolution. Quick competitions are then used to get the students to see some extinct organisms in the Dodo and Woolly Mammoth and again they are questioned on how extinct animals support the theory of evolution. Further evidence in rapid changes in species and molecular comparison is discussed. There are regular progress checks throughout the lesson so that students can assess their understanding and there is a set homework included.
This bundle of 8 revision lessons covers all of the topics on the AQA A-level Biology specification:

These lessons use a range of exam questions, quick tasks and quiz competitions to motivate and engage the students whilst they assess their understanding of the different topics and evaluate which areas of the specification will require their further attention. These lessons can be used for revision at the end of the topic, in the lead up to mocks or in the lead up to the actual exams.
This resource has been designed to motivate students whilst they evaluate their understanding of the content in modules 1, 2, 3 and 5 of the OCR A-level Biology A specification which can be assessed in PAPER 1 (Biological processes). The resource includes a detailed and engaging Powerpoint (149 slides) and is fully-resourced with differentiated worksheets that challenge the students on a wide range of topics.
The resource has been written to include different types of activities such as exam questions with explained answers, understanding checks and quiz competitions. The aim was to cover as much of the specification content as possible but the following topics have been given particular attention:
Monosaccharides, disaccharides and polysaccharides
Glycogen and starch as stores and providers of energy
The homeostatic control of blood glucose concentration
Osmoregulation
Lipids
Ultrafiltration and selective reabsorption
Diabetes mellitus

Helpful hints and tips are given throughout the resource to help students to structure their answers. This resource can be used in the lead up to the actual Paper 1 exam or earlier in the course when a particular area of modules 1, 2, 3 or 5 is being studied.
If you are happy with this resource, why not look at the one which has been designed for Paper 2 (Biological diversity)?
The AQA specification states that a minimum of 10% of the marks across the 3 assessment papers will require the use of mathematical skills. This revision lesson has been designed to include a wide range of activities that challenge the students on these exact skills because success in the maths in biology questions can prove the difference between one grade and the next!
Step-by-step guides are used to walk students through the application of a number of the formulae and then exam-style questions with clear mark schemes (which are included in the PowerPoint) will allow them to assess their progress. Other activities include differentiated tasks, group discussions and quick quiz competitions such as “FROM NUMBERS 2 LETTERS” and “YOU DO THE MATH”.
The lesson has been written to cover as much of the mathematical requirements section of the specification as possible but the following have been given particular attention:
Hardy-Weinberg equation
Chi-squared test
Calculating size
Converting between quantitative units
Standard deviation
Estimating populations of sessile and motile species
Percentages and percentage change
Cardiac output
Geometry
Due to the detail and extensiveness of this lesson, it is estimated that it will take in excess of 2/3 hours of A-level teaching time to work through the activities and it can be used throughout the duration of the course
This fully-resourced lesson has been designed to cover the content of specification point 5.2.2 (The brain) as found in topic 5 of the AQA GCSE Biology specification. This resource contains an engaging PowerPoint (33 slides) and accompanying worksheets, some of which have been differentiated so that students of different abilities can access the work.
The resource is filled with a wide range of activities, each of which has been designed to engage and motivate the students whilst ensuring that the key Biological content is covered in detail. Understanding checks are included throughout so that the students can assess their grasp of the content. In addition, previous knowledge checks make links to content from earlier topics such as cancer.
The following content is covered in this lesson:
The functions of the cerebral cortex, medulla and cerebellum
Identification of the regions of the brain on an external and internal diagram
The early use of stroke victims to identify functions
The key details of the MRI scanning technique
The difficulties of diagnosing and treating brain disorders and disease
As stated at the top, this lesson has been designed for GCSE-aged students who are studying the AQA GCSE Biology course, but it can be used with A-level students who need to go back over the key points before looking at the functionality of the regions in more detail
This bundle of 4 revision lessons covers the content in topics 1 - 4 of the AQA A-level Biology specification that are taught during year 12 (AS) of the two-year course.
Each of the lessons has been designed to include a range of exam questions, differentiated tasks and quiz competitions that will motivate the students whilst they evaluate their understanding of the different sub-topics.
Helpful hints are given throughout the lesson to aid the students in structuring their answers and the mathematical elements of the course are constantly challenged as well.
The 4 topics covered by this bundle are:
Topic 1:Biological molecules
Topic 2: Cells
Topic 3: Organisms exchange substances with their environment
Topic 4: Genetic information, variation and relationships between organisms
A detailed and engaging lesson presentation (52 slides) and accompanying worksheet that looks at competition between organisms and the different types of relationships that exist as a result of this interaction. The lesson begins by looking at the meaning of the biological term, "competition", and then introduces this when it occurs between the same species and different species. Students are challenged to consider the different resources that animals compete for before an activity based competition is used to get them to recognise how this competition can cause changes to the population size.
Moving forwards, students will meet the three main types of ecological relationship and look at them in greater detail, with predation being a main focus.
There are regular progress checks throughout the lesson (with displayed answers) so that students can assess their understanding.
This lesson has been designed for GCSE students but can be used with more-able KS3 students who are looking at ecosystems and the relationships that exist within them
This fully-resourced lesson explains how genetic fingerprinting can be used to analyse DNA fragments and explores its applications in forensic science and medical diagnosis. The engaging and detailed PowerPoint and accompanying resource have been written to cover all of point 8.4.3 of the AQA A-level Biology specification
Each step of the genetic fingerprinting process is covered and time is taken to ensure that key details are understood. Students will be introduced to VNTRs 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 and restriction enzymes are discussed and students are challenged on their knowledge of this process and these substances as they were encountered in a previous sub-topic. 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 topic 8 as well as those from topic 4 where DNA, RNA and protein synthesis were introduced.
This lesson focuses on the key terms associated with ecosystems and describes how populations are affected by a range of factors. The PowerPoint and accompanying resources are part of the 1st lesson in a series of 4 lessons that cover the details of point 7.4 of the AQA A-level Biology specification
As shown in the cover image, a modified version of the quiz competition BLOCKBUSTERS runs throughout the lesson and this introduces new terms as well as challenging students to recall key terms that were encountered in previous topics. These include population, ecosystems, competition, niche, abiotic factors and carrying capacity. Each time a term is met, time is taken to describe its meaning and to explain its relevance and context in this topic of populations in ecosystems. Exam-style questions are also used to challenge the students to apply their understanding and displayed mark schemes allow them to assess their progress. Prior knowledge checks interspersed within the lesson which check on topics such as the nitrogen cycle, adaptations and the biological classification of a species
This bundle contains 15 fully-resourced and detailed lessons that have been designed to cover the content of topic 7 of the AQA A-level Biology specification which concerns genetics, populations, evolution and ecosystems. The wide range of activities included in each lesson will engage the students whilst the detailed content is covered and the understanding and previous knowledge checks allow them to assess their progress on the current topic as well as challenging them to make links to other related topics. Most of the tasks are differentiated to allow differing abilities to access the work and be challenged.
The following sub-topics are covered in this bundle of lessons:

This is one of the 8 topics which have to be covered over the length of the 2 year course and therefore it is expected that the teaching time for this bundle will be in excess of 2 months
If you want to see the quality of the lessons before purchasing then the lessons on codominant and multiple alleles, epistasis and phenotypic variation are free resources to download
This fully-resourced lesson focuses on the events of meiosis which specifically contribute to genetic variation. The detailed PowerPoint and accompanying resources have been designed to cover the 4th and final part of point 4.3 of the AQA A-level Biology specification which states that students should be able to describe how meiosis produces daughter cells that are genetically different from each other.
In order to understand how the events of meiosis like crossing over and random assortment and independent segregation can lead to variation, students need to be clear in their understanding that DNA replication in interphase results in homologous chromosomes as pairs of sister chromatids. Therefore the beginning of the lesson focuses on the chromosomes in the parent cell and this first part of the cycle and students will be introduced to non-sister chromatids and the fact that they may contain different alleles which is important for the exchange that occurs during crossing over. Time is taken to go through this event in prophase I in a step by step guide so that the students can recognise that the result can be new combinations of alleles that were not present in the parent cell. Moving forwards, the lesson explores how the independent segregation of chromosomes and chromatids during anaphase I and II results in genetically different gametes. The final part of the lesson looks at the use of a mathematical expression to calculate the possible combinations of alleles in gametes as well as in a zygote following the random fertilisation of haploid gametes. Understanding and prior knowledge checks are interspersed throughout the lesson as well as a series of exam questions which challenge the students to apply their knowledge to potentially unfamiliar situations.
Due to the detail of this lesson, it is estimated that this will take about 2 hours of A-level teaching time to deliver
An engaging lesson presentation (61 slides) and associated worksheets that uses a combination of exam questions, quick tasks and quiz competitions to help the students to assess their understanding of the topics found within unit B5 (Genes, inheritance and selection) of the OCR Gateway A GCSE Biology specification

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.
A fully- resourced lesson which looks at the chemical reaction that is anaerobic respiration and ensures that students can understand why this form of respiration can only be used for short periods of time. The lesson includes an engaging lesson presentation (39 slides), a newspaper article and application questions.
The lesson begins by challenging the students to recall information about aerobic respiration to recognise that the sole reactant of anaerobic respiration is glucose. A newspaper article about two atheletes from the 10000m race has been written to challenge the students to recognise why one of the athletes wouldnt be able to compete again in the near future whilst the other could. As a result, students will be introduced to lactic acid and will learn how this poisonous substance prevents muscle contraction and causes cramps. Time is taken to ensure that students are familiar with ATP and specifically that they recognise that a much lower yield is produced in this type of respiration. A perfect opportunity is taken to get the students to carry out a mathematical calculation to compare the yields. Oxygen debt is discussed and related back to the original newspaper article. Finally, anaerobic respiration in plants and yeast is considered in terms of fermentation and the word and symbol equation is written so that it can be compared to those from animals.
There are regular progress checks throughout the lesson to allow the students to check on their understanding. The lesson has been written for GCSE students but could be used with higher ability KS3 students or A-level students who want a recap before covering the topic in greater detail on their course.
A series of 5 exam questions that challenge students to work out the actual size of a section as seen under a microscope or the magnification. These questions will test their ability to convert between measurements and give answers in micrometers. These questions are suitable for GCSE and A-level students
This detailed lesson describes the structure of a nucleotide and a phosphorylated nucleotide and explains how polynucleotides are synthesised and broken down. The engaging PowerPoint has been designed to cover points [a], [b] and [c] of module 2.1.3 as detailed in the OCR A-level Biology A specification and links are made throughout to earlier topics such as biological molecules.
Students were introduced to the term monomer and nucleotide in the previous module, so the start of the lesson challenges them to recognise this latter term when only the letters U, C and T are shown. This has been designed to initiate conversations about why only these letters were used so that the nitrogenous bases can be discussed later in greater detail. Moving forwards, students will learn that a nucleotide is the monomer to a polynucleotide and that deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) are two examples of this type of polymer. The main part of the lesson has been filled with various tasks that explore the structural similarities and structural differences between DNA and RNA. This begins by describing the structure of a nucleotide as a phosphate group, a pentose sugar and a nitrogenous base. Time is taken to consider the details of each of these three components which includes the role of the phosphate group in the formation of a phosphodiester bond between adjacent nucleotides on the strand. At this point students are challenged on their understanding of condensation reactions and have to identify how the hydroxyl group associated with carbon 3 is involved along with the hydroxyl group of the phosphoric acid molecule. A number of quiz rounds are used during this lesson, as a way to introduce key terms in a fun and memorable way. One of these rounds introduces adenine and guanine as the purine bases and thymine, cytosine and uracil as the pyrimidine bases and the students are shown that their differing ring structures can be used to distinguish between them. The remainder of the lesson focuses on ADP and ATP as phosphorylated nucleotides and links are made to the hydrolysis of this molecule for energy driven reactions in cells such as active transport
This clear and concise lesson covers the Link reaction and its site in the cell as detailed in point 5.2.2 (d) of the OCR A-level Biology A specification. The PowerPoint explains how the product of glycolysis, pyruvate, is decarboxylated and dehydrogenated and combined with coenzyme A to form acetyl coenzyme A which will then enter the Krebs cycle.
The lesson begins with a challenge, where the students have to recall the details of glycolysis in order to form the word matrix. This introduces the key point that this stage occurs in this part of the mitochondria and time is taken to explain why the reactions occur in the matrix as opposed to the cytoplasm like glycolysis. Moving forwards, the Link reaction is covered in 5 detailed bullet points and students have to add the key information to these points using their prior knowledge as well as knowledge provided in terms of NAD. The students will recognise that this reaction occurs twice per molecule of glucose and a quick quiz competition is used to test their understanding of the numbers of the different products of this stage. This is just one of the range of methods that are used to check understanding and all answers are explained to allow students to assess their progress.
This lesson has been written to tie in with the other uploaded lessons on glycolysis and the Krebs cycle and oxidative phosphorylation.
