Homework Help: Science

Posted by Celine on Tuesday, September 22, 2009 at 4:18pm.

There are two fill-in-the-blank questions that I can't find the missing word. If you could be of any help, I'd appreciate it. :)

#1. The ____ describes the steps you use during an experiment.

#2. Sometimes scientists make a mistake, or ____, and need to do an experiment again.

Thanks so much!
