Okay, This is my third topic for the science fair, my teacher turned down my other two. My first one was to get saliva samples from a human, and from a dog, and to put them in augur in a petri dish, and wait some time to see what has more bacteria. and my second one was just something i guess up, i would test out powder laundry detergent and liquid laundry detergent on stain to see what was more powerful, I am in 10th grade. And here is my third idea; Does listening to music while you study affect your ability to memorize facts? Is that one good, please help. Thanks
she declined the first 2 ideas, but she told us whether or not she accepted the idea on friday, and she assigned us 30 notecards on our topic due monday... so i have to make notecards on a topic that i dont know if she will accept it or not, it is really frustrating because she is making it really hard for us to do things, it pisses me off
