7th/8th Grade Science: 
In science we spent a good deal of time reviewing the details of yesterday's lab (identifying the independent and dependent variables, how to write a hypothesis statement, collecting quantifiable data, and organizing data in a data table).  We then discussed what information goes into the conclusion section of a scientific report.  Students spent the remainder of class writing the conclusion to yesterday's lab, (while considering the labs relevance to topics we've studied relating to properties of matter).
Homework: Write 1-2 questions relating to dry ice that could be answered by completing a scientific experiment.
EXAMPLE:  Does dry ice in vinegar sublimate faster than dry ice in water?
