5th & 6th Class investigated the effects of salt water and fresh water on gummy bears.
2 gummy bears were placed in water; 1 in a container with fresh water, the other in a container with salt water.
After a few days it was clear that the gummy bear in the fresh water had started to swell while the gummy bear in the salt water had generally kept its shape.
This experiment helped to show the class the effects that fresh water would have on some sea creatures like sharks if they were to leave the sea/ocean and enter a river.
