Again and again

For the science fair, we tried again and again. First we gathered and thought about lots of projects, and then we found many data. The problem is the time was very short, so we needed to think about easier things. We chose to feed the things that will be on the bad food, and observe them. We took maybe three weeks to do it, but then when we knew they won't let us use that project because it is not good for people's body. We were very sad.
