DiffusionOsmosis

This week we continued to work on our knowledge of the Scientific Method by demonstrating how osmosis works with gummy bears.  YUM!  What does this have to do with plants?  Well osmosis is how plants absorb water through their roots!

See lab results from last year here

See all about this lab and the scientific explanation here and a video explanation here

Diffusion - Distribution of particles from an area of high concentration to an area of low concentration until equilibrium is reached.


Before
After!  See how they have grown or shrunk!
