Come up with five ethical guidelines for research. Write statements that reflect your own views of
what is right and wrong. If you really love animals, an example of one guideline might be "No

thoughtful about what they really mean. Think of the information you read about earlier. Try to
phrase your guidelines in a way that would allow research that you think would be beneficial to
still be done. You may find that certain circumstances may cause you to rethink your own ethics!
