aim: to find what type of paper deteriorates the fastest, and in what liquid.
method:
- put different samples of paper into glasses, and into different liquids.
- take photos everyday, or every few days, depending on rate of decomposition.
independant variable: putting normal paper in water?
dependant variables: everything else.
some liquids to use:
- water
- vinegar
- oil?
- detergent water
- bi carb/water solution? (not sure)
- salt water
- sugar/water solution
different types of paper:
- normal paper (from school or something)
- higher quality paper.....
- photo paper
- hi gloss paper
- cardboard.
now that i think of it, i think thats a preeeety good idea, but i might have too many variables... i'll need to refine this eventually.
but in the meantime, please leave your interesting or creative responses in the comment section belooooow. :D

Sounds...papery. ;D (Because saying that it sounds 'nice' would be redundant. And I imagine it would not be 'nice' in particular.)
Everything is so BLUE... 8l
I actually think the idea your mum gave you is more creative! But it's up to you- both will be just as fine as each other. Think about how you're going to measure the decomposition rate.
You can measure voltage output by using a multimeter (can buy from Dicksmith Electronics for about $15 or so)...
