Not Again

yes, another snow day for my district....getting old. However the neighboring district that I sub for was still operating (and on time) so i worked a fell day in 7th grade science class. They were making poster of a cell analogy. A plant cell is like a school. The principal is like the nucleus and controls everything, the building is like the cell wall, the hallways like the endoplastic reticulum and on. The students made up their own comparative analogy and then had to draw it out and explain. I think it's a pretty cool assignment.....too bad I don't have a cell science section,
