To satisfy the Department of Education requirements a formal write-up should be entered into a hardback science copy. This write-up should include the following elements: 

1. TITLE: Experiment title and date. 

2. APPARATUS: List of equipment used. 

3. DIAGRAM: A fully labelled diagram of the experimental set-up. 

4. PROCEDURE: A brief description of what quantities were recorded and how they were measured. 

5. RESULTs: A table of the recorded data and a calculation using a formula. 

6. GRAPH: Drawn on graph paper if required. 

7. CONCLUSION: What the experiment achieved (if appropriate). 

8. ERRORs/PRECAUTIONS: Sources of error and ways in which the accuracy can be improved.

However, day-to-day repetitions of the measurement can differ slightly because of small variations in variables that are not controlled in our experiment, including changes in ambient temperatures, slight variations in the gauge and small impurities in the chemical composition of the wire (if different locations are selected), and current source drifts. Consequently, this experiment (as well as many we conduct) is said to have a random component. In some cases, the random variations are small enough, relative to our experimental goals, that they can be ignored. However, no matter how carefully our experiment is designed and conducted, the variation is almost always present, and its magnitude can be large enough that the important conclusions from our experiment are not obvious. In this case the thickness of the wire may vary significantly and so taking an average is an important part of the experiment.]]> 2019-01-12 22:06:31 UTC https://padlet.com/rdownes/pe2/wish/319988294 rdownes https://padlet.com/rdownes/pe2/wish/326114320 2019-01-31 02:15:22 UTC https://padlet.com/rdownes/pe2/wish/326114320 rdownes https://padlet.com/rdownes/pe2/wish/326132830 2019-01-31 04:25:04 UTC https://padlet.com/rdownes/pe2/wish/326132830
