[Nfb-science] science experiments (Shanthala Somayaji)

Fri Jan 25 19:41:30 UTC 2013

Hi,
I don't know If this will help your experiment directly but it might
help you come up with some ideas. In my biochemistry lab we did an
experiment with potatoe cylinders and salt solutions. Our experiment
was to view osmosis but it clearly showed how cells obsorb water.
Maybe, showing them how water is obsorbed first can aid in teaching
them this concept. Because the changes were physical and obvious in
the potatoe cylinders  that obsorbed water.
