I need ideas for a 4th grade science project. You have to be able to ask a question and do the experiment to prove it, its for my little sister and she really wants to win first at the science fair this year, but I'm having trouble coming up with a good project, that would be fun for her.

Needs:
a Question
Hypothesis
Experiment
Results &
Conclusion

I just need ideas for the question, and basic instructions. The rest we'll (obviously) figure out. lol. Any ideas? 10 points to the one I like best. Thanks!
