Good Grade 7 Science Fair Idea?
i have a labtop,tvs, all the glass mesureing stuff (beakers, test tubes) any good ideas???
Ok this idea won 1st place in the science fair the year before I did it. And it won me 3rd place when I copied a girl from the year before.
I did a project where the question was "Does the shape of ice affect how fast it melts?"
I dunno why but they thought it was brillant!
Whats On My YouTube Today?
