Science fair?

Kim asked:


I already have a science fair idea but it’s too elementary….how can I change it so it’s high school appropiate?

My experiment is: The effect of substances (sugar, vegetable oil, vinegar, salt, and glycerin) on how long soap bubbles last…

and my hypothesis is “If I add sugar to soap, then I will get longer-lasting bubbles because sugar slows down the evaportation of water that causes the bubbles to dry out and pop”

how can I edit it to make it appropiate for my grade level (im in 9th grade)

    Dont know about how to change the actual experiment, but changing the terminology might help a little, for example instead of vinegar put dilute acetic acid. Also if you actually explain why the evaporation is slowed, that would make you seem more knowledgable in that area, other than that, I dont know. Hope this helps.
