I am a huge fan of project-based learning! As a result, I create lots of rubrics. Sometimes I write them myself and other times, I like to find premade ones to help me clarify the assessment piece. A co-worker in Colorado introduced me to Rubistar years back. It's free and pretty user-friendly. They have several premade categories and criteria, but you can alter them to fit your needs. The website is old, but don't let that throw you off.
I'm just a science teacher sitting at my computer generating and finding ideas to make learning more enjoyable.
