Aim

I want to find out what happens to Gummy Bears when we put them into different liquids.

Perdition

I think that Gummy Bears will shrink or grow in the liquids 

Equipment

1. Three solutions - water, sugar and salt 

2. four Gummy Bears of the same colours   

3. Two Petri Dishes

If you put water in a cup then put a gummy bear in it what will happen  in my opinion it will  get a lot more smaller leave a comment telling me what you think.

The water that was included in the first gummy bear petri dish made the gummy bear change from a dry weight of 2.52 to a wet weight of 8.83.

The salt water petri dish from a dry 2.48 to a wet 5.19.

The sugar water petri dish from a dry 2.46 to a wet 4.81 

The gummy bear that changed the most was the gummy bear in the sugar water.
