This resource has everything needed to teach and learn about the heart at OCR A level. The booklet starts at the basic structure of the heart and the main structures of heart anatomy both internal and external. The Structure is explained using a simple gap fill activity to allow students to learn and complete the first page of the booklet. The next is labeling the external and internal structures to allow students to orientate themselves. The next part of the booklet explains the key stages in the cardiac cycle using a simple gap fill and then goes on to explain the cardiac cycle graph with clear labels of what is happening the pressure changes in the atria and ventricles. The next part of the booklet explains the initiation of the cardiac cycle how the cardiac cells are myogenic and how the natural pacemaker SAN node triggers a wave of excitation over the atria and how the AVN node triggers ventricular contraction. The last part of the booklet explains ECG graphs and what each part does and how to recognise abnormal ECG traces.

The booklet covers the difficult concept of how haemoglobin transports oxygen around the body and how the haemoglobin undergoes configurational change so that it bonds oxygen more easily after the first oxygen has joined. The booklet then introduces Oxygen dissociation curves why they are sigmoid shape and how they are made including what the partial pressures means in terms of tissues in the body. There are various amount of tasks in the booklet students are challenged to make a dissociation curve with some data and need to answer some key questions on what is happening at different parts of the graph in relation to partial pressure and haemoglobin shape. The booklet then compares haemoglobin with both myglobin the oxygen storage molecule found in muscles and foetal haemoglobin. Both have questions on what these molecules do and where they are situated on the oxygen dissociation curve graph in relation to adult haemoglobin. The booklet then introduces carbon dioxide transport in great detail and the three main methods it is transported in the blood. The booklet then finishes on the Bohr effect and how carbon dioxide affects the oxygen dissociation curve and what happens when different carbon dioxide concentrations affect haemogobin loading and unloading.

This resource covers the OCR syllabus on PLant transport- Translocation. Firstly it defines what translocation is and then further explains the key terms of source and sink regarding the translocation of sugars. The booklet then further explains the key cells the make up the Phloem tissue, their components and functions. It then goes on to explain the content of the sieve tubes and the reason why Sucrose is transported not glucose. The resource then explains how translocation occurs using the mass flow hypothesis. It shows the key mechanism how Sucrose is loaded into the phloem using a co-transporter. The booklet then shows with clearly labelled diagrams how sucrose is moved along the phloem. The finishing page focuses on the difficult 2021 Translocation question on how glucose produced in photosynthesis is translocated to parts of the plant where glucose is metabolised and stored.

This full lesson Booklet is the perfect resource to inform and educate students in the most latest developments of Biology in the 21st century. The Booklet begins introducing what the advancements in DNA sequencing have done and how they have produced a large amount of processed data and information and that this has resulted in the development of a brand new are n Biology called Bioinformatics. The booklet then explains as a result of all the information gathered comparison studies have been used to look at the firstly the genome size of different organisms and the number of functional genes they possess. The booklet then demonstrates an inter species comparison study looking at Beta haemoglobin and how a single mutation can lead to disease such as sickle cell anaemia and how Bioinformatics can compare all the different species data and find similarities are closely related to each other. The resource then touches on more complex disease such as cancer and the BRCA gene. The Booklet then explains how pharmaceutical companies are using Bioinformatics to focus on SNPs and using them to make new drugs. This then follows on into the NHS current project the 100,000 genome project and how Bioinformatics will be used. The booklet finishes on two exciting future developments using Bioinformatics synthetic Biology and Proteomics.

This Biotechnology booklet Introduces some key terms regarding Biotechnology and the many different uses of microorganisms in Biotechnology. The introduction of Primary and secondary metabolites and when they are produced in the microbial growth curve. There are some deep level thinking questions to challenge learners. The booklet then goes on to explain some key Biotechnological processes and the microbes involved covering : The production of food, pharmaceutical drugs, commercial enzymes and Bioremediation. The booklet then introduces industrial scale fermenters and the key factors that can affect microbial growth. The booklet contains picture of a standard fermenter and a power point resource that pupils can use to label and learn the key parts. The Booklet then briefly compares Batch and Continuous culture and the key differences between them. The last page contains the key terms of aseptic technique, asepsis and Contaminants and the results of what happens if contaminants enter in the fermenter and why asepsis is key to pure culture. Lastly the challenges faced when scaling up small scale fermenters to industrial scale.

This full interactive lesson booklet on DNA sequencing defines DNA sequencing then starts off explaining past techniques such as shot gun sequencing step by step and their associated problems. The booklet then focuses on Fredrick Sangers technique of DNA sequencing and how he first cracked the process using radioactive dideoxy nucleotides. The technique goes into detail step by step. The booklet then focuses on modern day sequencing and Next Gen sequencing. The booklet then focuses how flourescent dyes and high processing power computers have dramatically changed the rate at which DNA is sequenced. Lastly the uses of DNA sequencing have been covered

This extremely challenging content is easily explained in the OCR Biology A level Sliding Filament Theory Booklet It includes : Skeletal muscle Histology The structure of the myofibril The structure of a sarcomere How the muscle contracts -sliding filament theory How contractions change the pattern of banding Maintenance of ATP

This is a Booklet resource with answers and allows students to understand functions of the Liver by filling in the Booklet and using the diagrams provided. This can be activity can be done independently or teacher led. It can last the whole lesson and would be ideal with looking at Liver tissue or modeling out the Ornithine cycle

The resource is for pupils undertaking GCSE Science/ Biology and the topic of Monoclonal Antibodies how they are made and their uses. It consists of a starter and main activity that is called 7 monkeys ( This is a teaching and learning activity that really helps pupils remember a hard and difficult topic of Biology) Pupils will be given paper and the teacher will talk them through the process of making monoclonal Antibodies. This will be learned through pupils making their own diagrams and drawings to the sequence Two previous pupils drawing are attached to help for SEN pupils

Having learned about this in my Biochemistry degree. It has now been included in the OCR A level Biology A H420 Syllabus as a kind of introduction into cellular control. Having taught this for several years I have had to make my own resource as there is very little material out on it that is relevant to A level students and the textbooks don’t explain the Biochemistry fully. The resource is a Booklet gap fill with diagrams and the teacher telling them all about the various different mechanisms that control gene expression in organisms. It covers -Gene regulation-Transcriptional control : chromatin remodelling/Histone modification / Lac operon/cAMP-Post-Transcriptional control: RNA Processing /RNA editing-Translational control : protein kinases/inhibitory proteins/inititaion factors-Post-Translational control : phosphates/amino acid modification/folding proteins/cAMP modification

This power-point can go with the Booklet or on its own. It covers a whole lesson on the mechanisms that control gene expression in eukaryotes and prokaryotes. These include Transcription control e.g Chromatin remodelling and histone modifcation Post -transcriptional control e.g RNA processing and editing Translational control e.g Inhibitory proteins and initiation factors Post -translational control e.g phosphate groups and protein shortening

The lesson covers the key stage 3 UK National curriculum on Classification. The resource covers Classification based on groupings or branches. It looks into the main Kingdoms of life including plants and animals It compares invertabrates and vertabrates It looks at the key characteristics of Birds, Mammals, Reptiles, Amphibians and fish. It ends with a fun game on pupils Knowledge of animals Additionally there is some key points on how learning to learn at the end if there is time.
