How can a science student make a good prediction about what will happen an investigation that has not been done yet

Do not use the words “I, we” or any other first/ third person words. Instead, start off by saying “it is predicted that...” instead of “I predict.” Also, make the prediction short. Don’t try and make it long because it doesn’t need to be longer than two lines. I hope this helps
