A simple pictorial summary with explanation on the use of bacterial DNA to manufacture the human hormone insulin on an industrial scale.

Diagram showing the hormonal interactions controlling the mentrual cycle. Take from a scan of an OHP drawing I did, many many years ago now, but to my knowledge the science is still the same........ I have also included a JPEG with rhe same detail.

Save yourself some of that precious time, no need to trawl the interweb, use this package of Biology JPEGS (75 individual items) covering Yr7 - Yr11 Biology to support your presentations, documents, revision aids, classroom teaching resources etc.

Powerpoint presentations with associated word files for students to use as activities. Roles of FSH, LH and Oestrogen. Their effects and interaction.

A lesson originally put together for OCR 21st Century Science C1 (Foundation - weak students) with significant challenge but would be equally applicable for any exam board (AQA, EDEXCEL etc) to illustrate the concept of Cause and Correlation. Observed during inspection with this lesson. Very successful outcome. Potentially dry topic. Use a clearly incongruous link, in this case ice cream sales and hayfever cases lnked to pollen count to illustrate the difference between a 'cause' and a 'correlation'. The graphs for this are in the attached powerpoint. Once the difference has been highlighted, move on to collaborative work in the class with the attached work on nitrogen monoxide levels and hayfever and the instances of asthma in a given area. Graphs to be completed using the data on the sheets and the questions about the completed graphs also to be done. Differentiated starter questions are also attached (D- B grade).

Classroom poster showing the effect of ADH in the body when water concentration in the blood is high and low.

38 individual GCSE homework/intervention questions (Higher and Foundation), all the same format, including success criteria linked to the new specifications. Each homework question has an associated MODEL ANSWER. Both the question and the model answer have been formatted to fit an A4 page in exercise books. All are produced in WORD are are fully editable, so you can remove logos, week numbers, set own marking criteria etc. Questions include: Cell Organelles and Magnification Osmosis, Diffusion and Active Transport Genetics and Genetic Engineering Organisation Digestive System and Enzymes Circulatory System and Cholesterol Coronary Heart Disease Drug Testing Vaccines and Pathogens Antibiotic Resistance Microbes and Immunisation Photosynthesis Respiration Cell Division Fertility Hormones Blood Sugar Control Neurones and Synapses Stem Cells Natural Selection, Fossils and Evolution

To support literacy across the curriculum and obviously Science in particular here, these sentence construction frames are extremely useful in a number of different contexts. Students find this quite a challenge but do engage with this in an extremely positive manner. A good opportunity for collaborative work. They can be edited for differentiation purposes, with significant challenge for the most able and also access for the weakest/SEND. They have been used very successfully as starters, plenaries, end of topic summaries, revision tools, homework and also extensions and they can be adapted for any topic across the entire curriculum from Yr7 to Yr13. I have attached a number of examples with associated powerpoints to have up on the board as the students attempt the task, including..... Limestone Hydrocarbons, Fractional Distillation and Cracking Radiation Respiratory and Circulatory System The Atom, Reacting Masses and Rates of Reaction Transformers and Power
