Our classroom smells like onions

In Science 10, we have been looking at how science and technology have lead to our understanding of what a cell is and what it can do.  The accidental "invention" of the microscope is probably, hands-down, the greatest technology that has furthered our understanding of the smallest unit of life.  Today, we used the microscopes to look at wet mount cells of the membrane that is found between the layers of an onion.  We had to prepare the slides, draw scale diagrams and then stain the slides to see if we could see anything better or different.  Tomorrow, we will look at the critters swimming around in some water that has had hay steeping in it for a few days.
