Description
HODDER STOUGHTON EDUCATIONAL Cambridge IGCSE® Computer Science by Helen Williams David Watson
Providing guidance that helps students practice and troubleshoot their exam technique,these books send them into their exam with the confidence to aim for the best grades.- Enables students to avoid common misconceptions and mistakes by highlighting them throughout- Builds students' skills constructing and writing answers as they progress through a range of practice questions- Allows students to mark their own responses and easily identify areas for improvement using the answers in the back of the book- Helps students target their revision and focus on important concepts and skills with key objectives at the beginning of every chapter- Ensures that students maximise their time in the exam by including examiner's tops and suggestions on how to approach the questionsThis title has not been through the Cambridge International endorsement process. : EXPERIMENTAL SKILLS AND ABILITIES: Scientific enquiry: Using and organizing apparatus and materials: Observing, measuring and recording: Handling experimental observations and data: Planning, carrying out and evaluating investigations: EXPERIMENTS1: Characteristics and classification of living organisms1.1: Dichotomous keys2: Organisation and maintenance of the organism2.1: Plant cells2.2: Animal cells3: Movement in and out of cells3.1: Osmosis and water flow3.2: Turgor in potato tissue3.3: Osmosis and turgor3.4: Plasmolysis3.5: Partial permeability (dialysis)4: Biological molecules4.1: Food tests4.2: Application of the food tests5: Enzymes5.1: Extracting and testing an enzyme5.2: The effect of temperature on enzyme reaction5.3: The effect of pH on enzyme reaction6: Plant nutrition6.1: Is cholorophyll necessary for photosynthesis?6.2: Is light necessary for photosynthesis?6.3: Is carbon dioxide needed for photosynthesis?6.4: Is oxygen produced during photosynthesis?6.5: The effect of light intensity on the rate of photosynthesis6.6: Gaseous exchange during photosynthesis6.7: The importance of different mineral elements7: Human nutrition7.1: Energy from food8: Transport in plants8.1: Transport in vascular bundles8.2: Rates of water uptake in different conditions8.3: To find which surface of a leaf loses more water vapour9: Transport in animals9.1: Physical activity and pulse rate10: Diseases and immunity11: Gas exchange in humans11.1: Oxygen in exhaled air11.2: Carbon dioxide in exhaled air11.3: Volume of air in the lungs12: Respiration12.1: Using up oxygen during respiration12.2: Releasing energy in respiration12.3: Anaerobic respiration in yeast13: Excretion in humans14: Co-ordination and response14.1: Gravitropism in pea radicles14.2: Phototropism in shoots14.3: Region of response15: Drugs16: Reproduction16.1: Insect pollinated flowers16.2: The growth of pollen tubes16.3: Germination: the need for water16.4: Germination: the need for oxygen16.5: Temperature and germination17: Inheritance18: Variation and selection19: Organisms and their environment20: Biotechnology and Genetic Engineering20.1: The effect of pectinase on fruit pulp21: Human influences on ecosystems22: Past exam questions22.1: Practical past exam questions22.2: Alternative to practical past exam questions
