Expected response and marking instructions 1 aim (1 mark) 1 an aim that describes clearly the purpose of the investigation the word 'aim' is not required but the statement of the aim should be separate from the title acceptable versions of an aim could be: ♢ 'to investigate how the resistance of a lamp filament varies with. Carry out an investigation of the relationship between the length of a metallic conductor (eg nichrome wire) and its resistance introduction background research outlined and referenced firstly i researched this topic in my science book i found relevant information in my book about resistance, such as the fact that. The two physics ones were on 'the resistance of a wire' and the other one for physics is to do with the danger of mobile phones basically just talk about your method and why you did what you did for each part and explain how this will help your investigation, then talked about things i can improve and.
Blood metaphors abound in everyday social discourse among both aboriginal and non- aboriginal people however, 'aboriginal blood talk', more specifically, is located within a contradictory and contested space in terms of the meanings and values that can be attributed to it by aboriginal and non-aboriginal people in the. Of a wire affects its resistance in my physics coursework i am going to investigate the effect of the length of a wire on its resistance resistance is the measure of how easy it is for current to flow through a wire current is the rate of flow of charge through a conductor, and it is measured in amps using an. These draft guidelines support the implementation of the syllabus by providing teachers with a broader context for science education in the junior cycle, together with specific ideas and suggestions for classroom practice that can facilitate students in developing their knowledge, understanding, skills and attitudes in relation.
Marking scheme marking criteria for coursework b (hl) - physics guide to mark assignment total marks using conductors made of children's play ( modelling) dough, investigate quantitatively the effect on resistance, calculated from measurements of voltage across and current through the conductors, of changing the. Would you like your pupils to hear how physics can assist archaeological investigation and take part in a practical demonstration at your school contact the 'the work they had prepared for the pupils was excellent the girls very much enjoyed participating in the resistance survey of our school field as a department, we. Aim i am going to be studying the resistance of wire the purpose of this investigation is to see how length and thickness of wire affect the dependent variable, resistance prediction i predict that, as the length of the wire doubles, the resistance will also double, but as the cross-sectional area of the wire doubles, the.

Physics using conductors made of children's play (modelling) dough, investigate quantitatively the effect on resistance, calculated from measurements of voltage across and current through the conductors, of changing the conductor length and obtain data to establish whether dough colour has an effect on its resistance. Investigating how the resistance of a constantan wire is affected by its length introduction: in this experiment we will be investigating how changing the length of a piece of constantan wire will affect the resistance therefore the length will be an independent variable and all of the other variables we will try to keep the. In the conduction of this experiment i will be examining the resistance of a wire this experiment queries the relation between voltage and amps flowing through 5 different thicknesses of wires electricity is transported through the wire by electrons when a circuit is switched off and there is no electric current present the.
