- Google search the name of the disease or health condition with "non-profit."
- Look for an organization that has that name in the title.
- On the website, look to see if it is a non-profit devoted to educating and researching that issue.
- Search the website for "research" articles.

Questions & Answers
Question: What do you think of "Is laughter the best medicine?" as an essay topic?
Answer: Using a familiar saying can work for an essay if you do a twist on the idea. What would be interesting about this topic is any research that showed how mood and laughter could keep people healthier. The "placebo effect" might be part of what you'd want to talk about.
Question: What do you think of, "can coral reefs be regenerated?" as a science essay topic?
Answer: 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?
Question: What do you think of “Can caffeine help your memory?” as an essay topic?
Answer: It is better to ask a question which does not just have a yes/no answer. Here are some variations:
1. How does caffeine affect a person's memory?
2. How much caffeine hurts a student who wants to retain information?
3. Can caffeine really help a person be more productive over the long run?
Question: How would "Can venom from spiders and other animals really be used in medical treatment safely" work as a science essay topic?
Answer: 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?
Question: What do you think of "How can our environment be protected?" as a science essay topic?
Answer: 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?
Question: Do you have a suggestion of essay titles for "human cloning should be banned?"
Answer: That statement is your topic thesis or answer. You need to start with a question which is debatable. Here are some suggestions:
1. Should there be international limits to cloning?
2. What should we do about human cloning?
3. Is human cloning a good idea?
4. What should be the limits to using cloning technology?
Question: What do you think of the topic, "In what way does global warming cause a domino effect?" for a science essay?
Answer: It might be better to make a topic that is a bit broader and your question would be the answer. Here are some possibilities:
1. What are the broader consequences of global warming or climate change?
2. How will climate change affect different countries differently?
3. Who are the winners and losers in climate change?
Question: Can you suggest a great research title with the topic "Are the chemicals used in food packaging harmful to human health?"
Answer: You can use that question as your title because it explains what your paper is going to discuss. However, you might want to make the title shorter:
1. Does Food Packaging Have Health Risks?
2. How Harmful is Food Packaging?
3. Should Food Packaging Be Changed?
Question: Do you have any suggestions for a space-themed science essay?
Answer: 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?

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?

Virginia Kearney (author) from United States on February 24, 2014:
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.
