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 lesson describes the structure and functions of the organelles that are found in eukaryotic cells. The engaging and detailed PowerPoint and accompanying resources have been designed to cover point (a) in AS Unit 1, topic 2 of the WJEC A-level Biology specification
As cells are the building blocks of living organisms, it makes sense that they would be heavily involved in all 6 modules in the OCR course and intricate planning has ensured that links to the lessons earlier in AS unit 1 are made as well as to the upcoming topics in the other units.
The lesson uses a wide range of activities, that include exam-style questions, class discussion points and quick quiz competitions, to maintain motivation and engagement whilst describing the relationship between the structure and function of the following organelles:
nucleus
nucleolus
centrioles
ribosomes
rough endoplasmic reticulum
Golgi body
lysosomes
smooth endoplasmic reticulum
mitochondria
cell surface membrane
vacuole
chloroplasts
plasmodesmata
All of the worksheets have been differentiated to support students of differing abilities whilst maintaining challenge
Due to the detail that is included in this lesson, it is estimated that it will take in excess of 3 hours of allocated A-level teaching time to go through all of the tasks
All 3 of the lessons that are included in this bundle are detailed and fully-resourced with differentiated worksheets to cover the content of topic 3.4.2 (Mass transport in plants) as set out in the AQA A-level Biology specification.
Some students do not fully engage with this topic and therefore time has been taken to design each lesson so that it maintains motivation through a wide range of tasks. These tasks include quiz competitions which introduce key terms in a memorable way.
The specification points that are covered in these three lessons are:
Xylem as the tissue that transports water in the stem and leaves of a plant
The cohesion-tension theory of water transport in the xylem
Phloem as the tissue that transports organic substances in plants
The mass flow hypothesis for the mechanism of translocation in plants

This detailed lesson describes how recombinant DNA is produced using restriction endonucleases and DNA ligase and is inserted into other cells. The engaging PowerPoint and accompanying resources have been designed to cover points 8.18 & 8.19 of the Edexcel International A-level Biology specification.
The lesson begins with a definition of genetic engineering and recombinant DNA to allow students to begin to understand how this process involves the transfer of DNA fragments from one species to another. Links are made to the genetic code and transcription and translation mechanisms, which were met in topic 2, in order to explain how the transferred gene can be translated in the transgenic organism. Moving forwards, the method involving reverse transcriptase and DNA polymerase is introduced and their knowledge of the structure of the polynucleotides and the roles of enzymes is challenged through questions and discussion points. Restriction endonucleases are then introduced and time is taken to look at the structure of a restriction site as well as the production of sticky ends due to the staggered cut on the DNA. A series of exam-style questions with displayed mark schemes are used to allow the students to assess their current understanding.
The second half of the lesson looks at the culture of transformed host cells as an in vivo method to amplify DNA fragments. Students will learn that bacterial cells are the most commonly transformed cells so the next task challenges their recall of the structures of these cells so that plasmid DNA can be examined from that point onwards.
Time is taken to explore the finer details of each step such as the addition of the promoter and terminator regions, use of the same restriction enzyme to cut the plasmid as was used to cut the gene and the different types of marker genes.
As well as understanding and prior knowledge checks, quick quiz competitions are used throughout the lesson to introduce key terms such as cDNA and EcoR1 in a fun and hopefully memorable way
This bundle of 4 revision lessons covers the content in topics 5 - 8 of the AQA A-level Biology specification that are commonly taught during year 13 (A2) 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 5: Energy transfers in and between organisms
Topic 6: Organisms respond to changes in their environment
Topic 7: Genetics, populations, evolution and ecosystems
Topic 8: The control of gene expression
This highly detailed and engaging lesson which explains how a nerve impulse (action potential) is conducted along an axon). The PowerPoint and accompanying resources have been designed to cover point 8.3 of the Pearson Edexcel A-level Biology A (Salters Nuffield) specification which states that students should be able to describe how the changes in the membrane permeability to sodium and potassium ions results in conduction. This topic is commonly assessed in the terminal exams so a lot of time has been taken to design this resource to include a wide range of activities that motivate the students whilst ensuring that the content is covered in the depth of detail that will allow them to have a real understanding. Interspersed within the activities are understanding checks and prior knowledge checks to enable the students to not only assess their progress against the current topic but also to challenge themselves on the links to earlier topics such as methods of movements across cell membranes and saltatory conduction. There are also a number of quiz competitions which are used to introduce key terms and values in a fun and memorable way and discussion points to encourage the students to consider why a particular process or mechanism occurs.
Over the course of the lesson, the students will learn and discover how the movement of ions across the membrane causes the membrane potential to change. They will see how the resting potential is maintained through the use of the sodium/potassium pump and potassium ion leakage. There is a real focus on depolarisation to allow students to understand how generator potentials can combine and if the resulting depolarisation then exceeds the threshold potential, a full depolarisation will occur. At this point in the lesson students will discover how the all or nothing response explains that action potentials have the same magnitude and that instead a stronger stimulus is linked to an increase in the frequency of the transmission. The rest of the lesson challenges the students to apply their knowledge to explain how repolarisation and hyperpolarisation result and to suggest advantages of the refractory period for nerve cells.

The answers to all questions are embedded into the PowerPoint so students can use this resource outside of the classroom.
The delivery of the whole lesson will likely need at least 2 or 3 hours of contact time so this resource could be used with students in the final weeks building up to their paper 2 exam, or alternatively with students before their mocks on these topics.
A detailed and engaging lesson presentation (74 slides) which consists of a series of exam questions, quick tasks and competitions to enable the students to assess their understanding of the topics found within Module 2. All of the exam questions have displayed mark schemes with explanations so that students can recognise errors and misconceptions and address them. Students will thoroughly enjoy the numerous competitions which include "Name the 007 bonds" and "Biology catchphrase".
An engaging lesson presentation (70 slides) which covers a range of communicable diseases which are caused by each of the four pathogens and discusses how the spread of these diseases can be prevented. The lesson begins by challenging the students to make the link between communicable diseases and pathogens and ensures that they are comfortable with protoctists as this is a pathogen that a lot of them will not have met or at least known the name for. Moving forwards, a focus is given to each pathogen, looking at why they are so effective at causing disease and also looks at examples of diseases that they cause. A range of quiz competitions are used to introduce key terms and maintain engagement. The remainder of the lesson focuses on how the spread of these communicable diseases can be prevented and attempts are made to link to other topics such as contraception. Progress checks have been written into the lesson at regular intervals so that students can constantly assess their understanding and any misconceptions can be immediately addressed.
This lesson has been written for GCSE students (14 - 16 year olds in the UK) but can be used with both younger and older students.
This fully-resourced lesson describes the ultrastructure of eukaryotic cells and the functions of each of the organelles in these cells. The engaging and detailed PowerPoint and accompanying resources have been designed to cover points 3.1, 3.2 & 3.3 of the Edexcel International A-level Biology specification and therefore this lesson also describes how all living organisms are made of cells and that these cells are organised into tissues, organs and organ system in multicellular organisms.
As cells are the building blocks of living organisms, it makes sense that they would be heavily involved in all of the 8 topics in the Edexcel course and intricate planning has ensured that links to previously covered topics as well as upcoming ones are made throughout the lesson. The cell theory is introduced at the start of the lesson and the first 2 principles are explained. Students will see how epithelial cells are grouped together to form different types of epithelium in the respiratory tract and their prior knowledge of gas exchange at the alveoli from topic 2 is tested with a series of questions.
The rest of the lesson uses a wide range of activities, that include exam-style questions, class discussion points and quick quiz competitions, to maintain motivation and engagement whilst describing the relationship between the structure and function of the following organelles:
nucleus
nucleolus
centrioles
ribosomes
rough endoplasmic reticulum
Golgi apparatus

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.
