My science lab rules

I had to waste too much time constantly reminding the students of a few simple rules, so I decided to just post them. They've been good with following them in the beginning of the lesson but normally towards the end they start to waver from it. It doesn't bother me really because I believe that it should be loud when it comes to science, as long as they are keeping to the topic. I want to see them excited about it! It is such a pain trying to write now. It doesn't even look like my handwriting anymore. Actually, it takes me a while to write. The b, d, g, p, and q all have to be complete circles first before putting in the line. My kids look so cute in their goggles though, they come in pink and green. A few days ago they were all complaining that the goggles were too tight so I loosened all of them. What happens? They all then say it's too loose, of course!
