Preventing food spoilage with low water potential solutions such as salting and with jams etc Preventing food spoilage with solutions with low pH such as pickling Preventing food spoilage with heat treatment ovens and pasteurised milk Preventing food spoilage with Irradiation in canning and plastic wrapping

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

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

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

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.

This Booklet on Smoking and Vaping teaches clearly the diseases linked and the effects they cause. It goes into great detail starting with the Substances that are found in Cigarettes including Tar, Carbon monoxide and Nicotine. The booklet then explain the effects of Tar on the gaseous exchange system. Diseases that are explained in great detail are : Chronic Obstructive Pulmonary disease Chronic Bronchitis Emphysema Lung cancer Each disease is explained how Tar and smoking is the cause then further explaining Consequences, Symptoms and treatment. The Booklet then explains the effect of Nicotine and Carbon monoxide passing into the blood and causing changes in circulation. leading to Cardiovascular Disease. The three most significant Cardiovascular diseases are the explained Atherosclerosis Coronary heart disease Stroke The booklet then explains how Cardiovascular disease can be prevented the risk factors associated with it. The last section educates on the new trend of vaporised Nicotine . Users inhale vapor through the mouth from a usually battery-operated electronic device (such as an electronic cigarette). This section explains all of the substances found in vapes and their effects on the body.
