If Positive Controls Fail, Is Fair Project Usually Repeated?
Posted: Sun Dec 17, 2006 9:06 pm
Although this has not occurred (yet) as my child started growing bacteria today, what would happen if a child did his project and even the three positive controls failed? (I watched him swab his bacteria and wonder if his zig zags were too far apart when using a zone of inhibition to measure. ) Would he/should he need to do the project again or just state what he thinks happened? Thanks. We're getting ready to go on a vacation and I'm wondering if people do their projects over for their fairs if things don't turn out. I can't wait to see some bacteria grow and have his project be successful so we can think of other things around the holidays. Thanks again and Happy Holidays to each and every one of you science experts!
