Osmosis - Gummy Bears

 Hello today's post is about osmosis the movement of solvent through the wall of a solid. 

Our aim is to find out what happens to gummy bears when we put them into different liquids. My Prediction is the water will make it bigger. This is the definition of osmosis: In biology, osmosis is the movement of water molecules from a solution with a high concentration of water molecules to a solution with a lower concentration of water molecules, through a cell's partially permeable membrane. 

Equipment:

1. Three solutions - Water, Sugar and salt.

2. Four gummy bears of the same colour.

3. Two Petri Dishes.

4. Marker Pen.

5. Electronic Balance.

6. Measuring Cylinder.

7. Beaker.

Theses are our steps.

1. Get your equipment.

2. Label Petri dishes with Dry, Water, Salt Water, Sugar Water.

3. Weigh the Gummy Bears and record their weight of the Petri dish.

4. Add 40ml of the solution into the Petri Dish

EDIT:

Findings

The water that was included in the first gummy bear dish made the gummy bear change from a dry weight of 2.46 to a wet weight of 5.94. The difference between the two weights was 3.48. This means that the gummy bear absorbed 3.48 grams of water though the process of osmosis. Te salt water gummy bear dish has a change from a dry weight of 2.48 and a wet weight of 3.90 that mean the different's was 1.92 grams. Lastly we did one last one with sugar water. When the bear was dry it was 2.45 gram and when it was wet it was 6.01 the difference was 3.56. 

The one that changed the most was the sugar water so if you have them you can do it at home its fun but you have to wait 24 hours after you put it in.
