Osmosis: The movement of solvent through the wall of a solid.
Sodium-Chloride = Nacl (salt)
Aim:
I want to find out what happen's to the Gummy Bears when we put them into different liquids?
Prediction:
I think the Gummy Bears are going to grow and soak up some of 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. Lable petri dishes with, DRY, WATER , SALT WATER, SUGAR WATER
3. Weigh the Gummy Bears and record their weight on the petri dish
4. Add 40ML of the solution into the petri dish
Findings:
Weight change
Yellow ( 2.20 ) too 1.88
Green ( 2.22 ) too 3.15
Red ( 2.35 ) too 4.62
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 form a dry weight of ( 2.35 )To a wet weight of ( 4.50 ) The differences between the two weights was that in the water it absorbed more liquid.This means that the gummy bear absorbed the amount through the progress of osmosis.
The salt water gummy bear petri dish had an chance of a dry wight of (2.20 ) To a wet weight of (2.60)The difference in these weights are that the salt water one grew more...
The sugar water solution in the petri dish with the gummy bear made this gummy bear weigh (3.29) this means it absorbed (1.07 )water total.
The gummy bear that changed the most was the gummy bear in the normal water.
