  1. Google search the name of the disease or health condition with "non-profit."
  2. Look for an organization which has that name in the title.
  3. On the website, look to see if it is a non-profit devoted to educating and researching that issue.
  4. Search the website for "research" articles.
  5. There will sometimes just be a description of the research which you may need to Google search in order to find the article. Often, they may even provide links to the research article or the article to download.

Questions & Answers

  • Do you have any suggestions for a space-themed science essay?

    1. How big is space?

    2. What do we not yet know about the universe?

    3. What happened in the first few minutes of our universe?

    4. What is "dark matter?"

    5. What is the likelihood that life exists in some form on other planets?

  • What do you think of, "can coral reefs be regenerated?" as a science essay topic?

    Here are some other topics to consider:

    1. How important are coral reefs?

    2. What important organisms live inside of coral reefs?

    3. How is pollution affecting coral reefs?

    4. What is the history of coral reef destruction and regeneration?

  • What do you think of "How can our environment be protected?" as a science essay topic?

    That is a good an important issue to discuss. However, it would help to narrow the question a bit to make it easier to research. "The environment" is a big topic, so one way to narrow it would be to focus on a part of the environment. Another way to make a question better is to use "what is the best way" or "what is most important" statements to qualify the idea. Here are some possibilities:

    What is the best way to improve our air quality?

    Which is the most important focus for environmental activists?

    How can an individual best help protect the earth?

    What can college students do to protect the environment?

    Which nonprofit environmental group is doing the most to protect the environment?

    How can governments best protect the environment?

    How should (put name of country here) protect the environment of their nation?

  • How would "Can venom from spiders and other animals really be used in medical treatment safely" work as a science essay topic?

    Great topic idea. Here are some others:

    1. How can spider venom be helpful in medical treatment?

    2. What makes spider venom and other toxins from animals unique?

    3. What type of spider venom is most useful in medical treatment?

    4. What are the uses that humans can make from what spiders produce?

      Great idea mahnoor. My husband is a plant researcher, so I should certainly add those sorts of topics and I do have some on my other lists. We just went to see the new Food Evolution movie last night.

      If you get a chance to see it, I'd suggest that you go. Here are a couple of topics inspired by the movie: How did the GMO controversy get started? What can be done about the banana wilt which is causing the banana crops to be destroyed? How important was the Green Revolution? Do plants have feelings? Can the world be fed by organic crops alone?

      Thanks Donna--I find topics by looking at recent science research. There are so many new discoveries being made all the time! In fact, since all of my topics are taken from recent articles and research, that makes it easier for students to find sources if they need to use them in the paper. I probably need to add that in the article.
