Osmosis- Gummy Bears!

 Osmosis: The movement of solvent through that wall of a solid.

Aim: 

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

Prediction:

I think the Gummy Bears are going to shrink or grow in the liquids 

Method: 

Equipment 

- Three solutions- Water-Sugar- and salt

- Four Gummy Bears of the same colour 

- Two petri Dishes 

- Maker pen 

- Electronic Balance 

- Beaker 

Steps 

1. Get your Equipment 

2. Label Petri dishes with DRY, WATER, SALT WATER, SUGAR WATER 

3. Weight the Gummy Bears and record their weight on the petri Dish. 

4. Add 40mL of the solution into the petri dish. 

Findings:

Weight change 

Solvent 

Dry

Wet

Water

2.35

4.50

Salt water

2.20

2.60

Sugar Water 

2.22

3.29



FINDINGS:

The water that was included in the first gummy bear petri dish made the gummy bear change from a dry weight of (2.35)  to a wet Weight of (4.50) The difference between the two weights was the water in the water it absorbed more liquid  This means that the Gummy  bears absorbed this amount through the progress of osmosis. 

The salt water gummy bear petri dish had a change from a dry weight of 2.20  TO a wet weight of (2.60)  The difference in these weights are that the salt water grew more. 

The sugar water solution in the petri dish with the gummy bears made the gummy bear weigh 3.29 This means it absorbed 1.07 water in total 

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