Osmosis Part 2

So it turns out the salt one has in fact stayed the same size, as i predicted. The word that can be used to compare the solution and the gummy bear is Isotonic. The gummy bear is isotonic to the salty solution.

The sugar solution has made the gummy bear bigger, contrary to my prediction. The scientific term hypertonic or hypotonic based on the arrangement of the statement. The gummy bear is hypertonic to the sugary solution.

The dihydrogen oxide solution (water) has made the gummy bear much bigger, to the point where the gummy bear's depiction of a membrane has broken. The gummy bear has absorbed water as I predicted however I did not predict the logical breaking of the membrane. This can also be considered hypertonic or hypotonic based o the arrangement of the statement. The water is hypotonic to the gummy bear.

Osmosis

Some gummy bears have been left in varying water mixes. This is an experiment to prove the existence of osmosis, AKA water diffusion. Since water balances concentrations of molecules on different sides of a membrane it is likely to affect the gummy bears. At a guess the gummy bear in the salty water will likely stay the same size. At a different guess the gummy bear in sugar water is likely to shrivel up. At a final guess the gummy bear in the water water is likely to absorb water.

We were told we should add pictures of gummy bears.
