K so this is the right way to do things right?
1. Aim (basic shiznit, what you're trying to find)
2. Hypothesis (Directly testable statement, eg "That xyz will cause qmp to happen"
3. Equipment (List EVERYTHING)
4. Method (3rd person past tense)
5. Results (Usually tabulated yea?)
6. Discussion (Connect results to hypothesis and suggest reasons as to why or why not the experiment supported or disproved the hypothesis)
7. Conclusion (Statement of results against the hypothesis, whether true or false)


Dis right, innit?

In the discussion, you also talk about validity, reliability and accuracy - sometimes you discuss how the phenomena observed occurred.

Waaait whats difference between reliability and validity agian.... is it VALIDITY is the extent to which the experiment coincides with the aim, and reliability the repetition of the experiment for more consistent results? YEa how the phenomena (lol "Phenomena" haha) occurred as in "THis caused this to happen" and "This happened because of that" mmhm?

Oh and whats the definition of accuracy? Accuracy of measurements is it?

Validity - the extent in which variables were controlled, a valid experiment will control any variable that has the potential to change the results (other than the independent variable) examples: use of distilled water, valid measuring systems where possible...

Reliability is the ability of your experiment to be repeated and the same results gained each time.
