What are serial solutions?
Involves stepwise series of dilutions where dilution factor remains constant, resulting in linear decrease in concentration.
What does photospectroscopy do?
Measures the absorption of light in a sample using a spectrophotometer.
What are the parts of a spectrophotometer?
Light source, monochromatic, exit slit, sample cuvette containing test solution, detector and amplifier/readout.
What is Beer’s Law?
The absorption of light is proportional to the number of molecules in the solution being measured.
What is the equation of the line of best fit?
Y = mx + b
What ways do scientists present their findings?
Talks, conferences, research papers, media.
What are the components of a scientific paper?
title, list of authors, afflictions, abstract, introduction, methods & materials, results, discussion, conclusion, reference list
What language should be used in a report of paper?
Passive voice, use of past tense, clear and logical flow, unbiased.
What should the title contain?

What should the introduction contain?
- Introductory sentence about field of research 2. Background info and previous work done in area, present limitations or assumptions on previous work done in area 3. Last paragraph states clearly aim and hypothesis of current study
What should the materials and methods section contain?
how experiment was performed and conditions it was competed under, details on instruments and equipment, details on techniques used to collect and analyse data, summary of important part of method so someone could repeat experiment
What should the results section contain?
Description of what you found from experiment, analysis of data, description of observational data, use of figures
What should the discussion section contain?
short summary of major findings, indication if hypothesis has been supported and if aim/objectives have been achieved, what results mean, your interpretation of results, how results compare to previous literature, shortcomings and limitations, general conclusions
