So... my challenge today is to liven up my science classroom. Not being a science teacher by training, I'm nearly clueless about how to do this.

Noah and Elizabeth didn't want to stay put in the nursery today -- midway through hour 2 of 7th/8th grade Life Science, my classroom door opened and Elizabeth strolled in. "I FOUND you!" she exclaimed.

I'm not sure this no-babysitter thing is going to work.
