Tactics (1)

A few comments on tactics:

1. Sometimes the search mechanism in Nature and Science come up empty without good search terms. So experiment and try different keywords, such as
   1. "renaissance"
   2. "pigment"
   3. "Martin Kemp" (co-founder of Universal Leonardo)
   for da Vinci topics, and
   1. "spherule"
   2. "comet, carbon"
   3. "detonation"
   for Younger Dryas topics. Experiment and be creative.
2. You won't find an article that is dedicated completely to your answer, "The answer is that..." which would be nice. Your answer must be put together from pieces of information, so read carefully and look for nuggets that help you build up your answer.
3. There is sufficient room in these questions that each member of your group might have a significantly different perspective on the answer. E.g, someone might concentrate on iridium and another on carbon. So don't be put off by that, but learn from it and become more wise.
4. The journal Science is weird. If the two archive links, items 6.2 and 6.3 in the Writing module, are not working for you, especially 6.3 for Science, then go in through the UCF Library's website directly, which you can all do. Log in, then click the Online Journals link and type in Science in the Journal Title box and hit the GO button. This will get you rolling.
