(2 questions) first of all, i dont have any science fair projects, have any good ideas for middle school? it has to has like an experiment with it (for example showing how plants get affected by adding food coloring). the experiment can be a before-hand, then you demonstrate. question 2: do you know any very fast germinating (less than 2 weeks) plants or flowers? and can you grow a sunflower during late winter (like now). so much for answering, answer both questions!

Hershey and chase confirmed that dna, not protein, was the genetic material. how do the results of their two experiments support this conclusion?
