complex topic

My newly developed topic is, how can you turn a liquid from the stages of ice, liquid, than to gas, and how are the molecules arranged differently in each phase.

My fellow group mates gave me ideas to try and rephrase my search, and they gave me words to use such as, 'molecular activity, molecules in ice, changes from phase to phase, and temperature of ice, water, and steam.' These different words to use can open up my search and broaden my search results, and ultimately help me find the answer to my cluster topic.

First article-I searched the words ice and water, and I found an article of help for me. I found that the database would give broad answers to your search, so I tried to narrow my search and make it as specific as possible. The article that I found was a scholarly one, as it was written by an expert or by someone who has a strong knowledge in the field of water quality. Some new steps would be that I be more specific in my search and find a smaller article.

Second-The second article I found by searching ice and water again, and I found a quality. I only found one article, so that was an obstacle. The article is trade/professional as it doesn't seem to be written by an expert. Next time I would like to find more results.

Third-For my third article, I found a very specific article on ice molecules, as those were the terms that I entered. A difficulty was that the article and database were a bit confusing, but nonetheless helpful. The article is scholarly as it was written by a German professor, and he uses very scientific and specific terms about the topic. Next time, I would try refine my search and make it more direct, as some of the results that I got weren't entirely relevant to my search.

I suspect your challenge in finding as much as you want is in your search phrases. It's generally not a good idea to include preposition, as in "molecules in ice." You'd be better to use "molecules" AND "ice," where AND is a Boolean operator. Otherwise, the results you'll get will all require the phrase "molecules in ice" to be present. In some cases, that might work well; in others, not. You might try both and see what differences result.

The same is true of "changes from phase to phase," which I might restructure to
"changes" "phase"
or
"changes" "phase to phase"

thereby separating the concepts and allowing them to appear anywhere in the record, not necessarily next to each other.

As for the article in a trade/professional journal, that might well be expert; it's just more difficult to verify. I suspect that it might be useful and valid, nonetheless.
