Google Scholar's searches are set to cover scholarly material more often than 'regular' Google. Google Scholar's searches are set to cover scholarly material more often than 'regular' Google. It can be frustrating, as much of an article or book is missing or by purchase only. Read the article below on the advantages an disadvantages of using it.
TIP: To get PDFs only, type in 'filetype:pdf'. It's great!
Advantages / Disadvantages of Google Scholar
Google Books can be very frustrating because often much of the book is missing and you are expected to purchase it to read the full content. So after you put in your search term you are interested in (eg biodiesel), and get some results up, you should then go immediately to the search box (on the left - above 'About this box') 
and type in a particular word or term you are interested in (eg CO2 emissions OR methanol) you should get a number of pages pop up. Choose one that looks useful - you should get some good results this way!
WHAT IS A RESEARCH QUESTION?
A Research Question is defined as ‘A question that directs the scientific inquiry activity. Its purpose is to focus the research investigation, inform the direction of the research, and guide all stages of inquiry, analysis, interpretation and evaluation’. It should:
1.3.1 Include measurable variables – the independent and dependent variables
1.3.2 Have a guiding word, such as what, why, would or will
1.3.3 Be phrased so that a definitive answer can be developed
1.3.4 Be able to link the guiding word to verbs such as identify, describe, compare, contrast, distinguish, analyse, evaluate or create so that a specific task can be determined
ELEMENTS OF A RESEARCH QUESTION (from Dr Cam Brooks)
EXAMPLE OF A SPECIFIC RESEARCH QUESTION
Should patients over the age of 80 years be permitted to undergo triple bypass operations? (Too broad)
SUBSTITUTE WITH
