Getting Started  Turn your phone off whilst you are revising. It will only distract you.  Create a working environment. Make sure you have paper and pens. A tidy desk is a tidy mind.  Plan what you are going to revise before hand. The Actual Revision  Do not try and revise for hours on end, you will only get bored.  Split your revision up into manageable chunks. 30-45mins MAXIMUM.  Therefore, do take breaks (15/20mins).  Do not revise lots of the same subject in one day, you will get bored. Vary your subjects to keep your brain engaged and to keep revision fresh.  Drink lots of water. A hydrated brain is a fully functional brain.  Do exercise during the day – active body, active mind.  Make sure you eat. Your brain will use lots of energy revising.  If you want to listen to music, try classical music. You won’t have the problem of lyrics effecting your revision. 3. Top Techniques Record yourself saying facts and then you can play it back to yourself. Make revision flash cards, with key words, phrases, ideas on. Get someone to test you. / Do past exam papers! Revise in the morning – Do not go to bed late. Sleep in important! Make spider diagrams – use colourful pens. Make revision notes and rewrite them to embed information. Don’t just revise the subjects you like! Reward yourself for achieving targets but do not get demoralised if you fall behind. If necessary amend your objectives to a more realistic level.  APPENDIX 1 Exam questions – It’s very important to make sure your answer gives what the question is looking for. Here are some key words to look out for to guide your answer. Account for: Give reason for; explain why something happens Analyse: Examine in very close detail; identify important points and chief features Comment on: Identify and write about the main issues. Avoid purely personal opinion Compare: Show how two or more things are similar. Indicate the relevance or consequences of these similarities Contrast: Look at and discuss the differences between things Criticise: Give your opinion and use evidence to support it Define: Give the exact meaning of Describe: Give the main characteristics or features of something or outline the main events Discuss: Write about the important aspects of the topic. Consider the arguments for and against. Support your point of view with reasons Evaluate: Assess the worth, importance or usefulness of something, using evide There will probably be cases to be made both for and against Examine: Put the subject “under the microscope” looking at it in detail Explain: Make clear and understandable how something works Illustrate: Give examples which make the point clear Interpret: Explain the meaning in your own words Justify: Give reasons to support an argument Outline: Give only the main points, showing the main structure Relate: Show the connection between things State: Write briefly the main points Summarise: Bring together the main points only omitting details or examples To what extent: Consider how far something is true or contributes to a final outcome Trace: Show how something has developed from beginning to end  APPENDIX 2 REVISION TIPS FOR DIFFERENT SORTS OF LEARNER S Here are ways you might try to help you with your revision. I have divided them up into sections for different sorts of learners. On the other hand, if you think any tip in any section will help, give it a try! REMEMBER! Trying to revise is useless if your books and files are not tidy and in order. GET ORGANISED! Visual learner  Mindmapping  Put posters/ post it notes on walls  Draw pictures/diagrams alongside notes  Use colour coding and highlighting  Use computers/Watch videos to support topics  To review information close eyes and see what you remember  Study in a quiet place away from verbal disturbances  Auditory learner  Taping notes and play them back  Discussing revision with your friends/work buddy  Reading notes aloud – works well for lists formulae etc. Speak list aloud rhythmically  Asking questions of yourself  Devise quizzes with a friend and test each other Physical/kinesthetic learner  Walk about talking to yourself  Make revision cards and put them in sequence. Question on front, answer on the back. Colour code them  Explain a topic to someone else to help you remember it  Underlining and highlighting can help you learn  Listen to music while you work Mindmap- example  8Aa- Nutrients 8Ab – Uses of nutrients End of 8Ac – Balanced diets Term 8Ad - Digestion Assessme 8Ae - Absorption nt outline 8Ca – Aerobic Respiration 8CB – Gas exchange system 8Cc – Getting oxygen  TYPE USE Found in Carbohydrates Energy Pasta, Rice, Bread Lipids (fats) Energy reserves, insulation Oil, Butter, milk , cream, avo Protein Growth and Repair Meat, Fish, chicken, eggs Minerals Building material for healthy bones, Milk , fruits & veg, meat and cereal teeth etc. Vitamins Healthy body functioning Fruits & vegetables Fibre For a healthy gut Fruits & veg, cereal Water Water! 75% of the body 2024-12-27 12/27/2024 2024-12-27 Starch test food examples: Test for fats Respiratory system Practice MCQs 1.Which of the following are nutrients found in food? a) Vitamins, Minerals, Fibre b) Water, Proteins, Carbohydrates c) Sugars, Salt, Fat d) Fibre, Protein, Fats b)Water, Proteins, Carbohydrates 2.Which nutrient supports growth and health? a) Protein b) Fibre c) Fat d) Salt a) Protein 3.What is the first step of digestion called? a) Egestion b) Ingestion b) Ingestion c) Absorption d) Defecation 4.

Mouth, oesophagus, liver, stomach, pancreas, small intestine, large intestine, rectum The human body requires essential nutrients for growth, energy, and maintaining overall health. Carbohydrates, which are broken down into , serve as the Glucose energy primary source of , while proteins repair and build tissues. , which Fats provide insulation by forming a layer under the skin, also store energy. Vitamins and minerals support bodily functions, such as vitamin preventing scurvy and strengtheningC bones and teeth. Fibre, found in fruits calcium and vegetables, is crucial for maintaining digestive health by preventing. Constipation Digestion involves four main steps: ingestion, digestion, absorption, and egestion. Food is first broken down mechanically and chemically in the mouth, where enzymes like start breaking down carbohydrates. In the stomach, food is churned and amylase mixed with acid and enzymes, such as , which digests proteins. Bile, produced Protease by the , emulsifies fats, making them easier to break down by lipase. The liver majority of nutrient absorption occurs in the small intestine, where digested food molecules pass into the bloodstream. absorption occurs in the large intestine, ensuring hydration. The muscular contractions that move food through the digestive Water tract are called peristalsis. Finally, undigested material is removed from the body through.
