How do I come up with a research question?
May be something that annoys you about computers & how they work. “Why doesn’t someone make computers do this or that?” – like Tim Berners-Lee. Starts with general interest in subject followed up by reading then a question emerges as knowledge grows.

Research questions
Research – answering questions. To start research, need at least one question. Large project may have more than one question. Too many questions – unable to answer them all, research will lack focus. Generally, 3-5 related questions. Should be refined to fairly basic terms: Why does this happen? How does that work? What is needed…

Research Activity 03
Verification of statements Try to find where and when Einstein made the declaration “nuclear power was impossible because it would require the splitting of the atom at will.”. What conclusion could you draw if you can’t find anything reliable to support the assertion that he made the statement about splitting the atom? I couldn’t find…

Research cycle
Not linear, never “finished” – it’s a cyclical process. Research throws up more questions than it answers. Not all questions can be answered – not enough time or resource. Further research of something leads to refinement. Can call previous research/concepts into doubt. Einstein said that nuclear power would be impossible as requires atom to be…

Research Activity 02
Hypercard: what it enabled a user to do and how it worked, and what was the major limitation of it and its imitators at the time. Hypercard allowed a user to store information in a “stack” similar to a Rolodex system. It also had the ability to process script with each object in the stack…

Find out more about the Osprey tracking. http://scottishwildlifetrust.org.uk/things-to-do/osprey/ Two chicks tagged with satellite trackers in 2015. In 21015, one fly 7352km and the other 6812km. Interestingly, the tracked ospreys don’t always take the same route, some travel along the west coast of Britain, another down the east coast and one more centrally. http://www.ospreys.org.uk/category/satellite-tracking/ The osprey…

Why research?
Simple answer – find things out. “body of knowledge” – everything we currently know. No one knows all of the body of knowledge but some people know each aspect. e.g someone may know all about atoms and how to build machines to answer questions about them, others may know all the winners of the Eurovision…
