NC SCoS Biology Cell Transport and Cell Division

Students were using microscopes to view living cells (red onion) with fresh water and when salt water was added.  After students saw the cells shrink with the addition of salt water, I challenged them to collect before/after pictures using their cell phone cameras.  They did beautifully!

We then shared these with an ELL Biology class during the same period.  I repeated the exercise the following week as we observed the stages of mitosis/cell cycle with onion root tip slides.  Students who could not distinguish among the stages could then use the pictures taken by their classmates for assistance,  I projected these the following day in my classroom.

Students were given bonus points on their lab if they emailed me the digital photos.

I think this was a great use of their own technology.  I think I might have them process the pictures (add labels, etc.) the next time I use this.
