An experiment suitable for gcse science to measure how the resistance of a thermistor changes with temperature. For this investigation, i believe that altering the length of the wire throughout the experiment will be the best method investigation into how the length of wire in a circuit affects the resistance planning section ---------------- science theory ==== ========== the information in the science theory section and the prediction. And as part of the course you will also receive some training in methods for antimicrobial susceptibility testing (ast) and detection of specific resistance in the coursework each course is like an interactive textbook, featuring pre- recorded videos, quizzes and projects help from your peers connect with thousands of. Physics coursework title 2017 changing the conductor length and obtain data to establish whether dough colour has an effect on its resistance part 1 ( introduction) (i) statement or problem to be investigated what other observations to note include did you encounter any problems with the experimental method. Method in order to test how the resistance of a particular material is related to its length and cross sectional area, an experiment in two parts must be conducted the first part has the length as the independent variable with all other variables controlled the second has the cross sectional area as the independent variable. The classic physics experiment this was designed as an intro for an isa but could be used for this practical in any syllabuss it includes model results, info on variables , anomalous data and graphs.
Carry out an investigation of the relationship between the length of a metallic conductor (eg nichrome wire) and its resistance introduction i did a trial run to get a 'feel' for the experiment i did the experiment twice to get the average i made sure that the wire was not kinked or looped and that the ends were cut correctly. Typical setup to measure the resistivity of a wire note:that the battery/cell and rheostat (variable resistor) can be replaced by a variable power supply equipment 1m of constantan wire of nominal diameters 027 and 056 mm, 1m of nichrome wire of nominal diameters 027 and 056 mm constant. What the investigation is about your task was to find out how the length of a wire affected its resistance most of the resources and information you need are in the science shared area of the network before you started the experimental part you found out about the scientific reasons for resistance. Hi, good example in deed and can show my students what a good project coursework entails can you avail me the opportunity to use it in my class if so please send to [email protected], keep up the good work,cheers 1 year ago reply are you sure you want to yes no your message goes.
Agar dilution method follows the principle of establishing the lowest concentration of the serially diluted antibiotic concentration at which bacterial growth is still inhibited 2-23-disk-diffusionjpg on this agar plate, a bacterial isolate is tested for resistance to each of twelve different antibiotics the clear zones around each. Summer research program for science teachers ghulam firdaus law and public service hs, manhattan august 2005 how to find out the unknown resistance of a wire through a series circuit background knowledge students should have already learned: the fundamental concepts of voltage, current, and resistance.
Mandatory practical work (coursework a) that you will carry out as part of the junior certificate science title of each activity refer to the possible method described for the activity in discovering science 2nd edition potential difference (voltage) and resistance, and establish the relationship between them to set up a. Resistance and length before you start the experiment read through the instructions carefully purpose of the experiment the aim of this experiment is to help you investigate how the length of a piece of wire affects its resistance.
Resistance of a wire essay 1284 words - 5 pages method- set p the equipment as shown on the diagram- one meter length of wire is fixed to a one meter ruler- the first crocodile clip is clipped to the wire at the 0cm position on the one meter ruler- the second crocodile clip is clipped to the 10cm position- the power. Scientific method coursework was introduced to science syllabuses in the early 1990s, attempting to address the concern that some students are not very good at exams whole investigations the independent variable is the one that we change (eg by changing the length of resistance wire) the dependent variable.
