Gummy Bear Osmosis

hello everyone! in science we are putting gummy bears in different liquids to see what happens and what the taste is like, the liquids were: normal water, sugar water (sucrose), salt water and for the forth one we didn't put any liquids. 

Aim:

I want to find out what happens when gummy bears are put in liquids 

Method: 

Equipment 

• Safety glasses 
• Sodium Chloride (Salt water) 
• H2o (water)
• Sucrose (Sugar Water) 
• Gummy Bears 
• 2x Petri Dishes 
• Marker 
• Electronic Scales 

Instructions 

1. Get your equipment 
2. Wear safety glasses 
3. With a marker write your name and the conditions and the weight of the gummy bear on the lid 
4. Do the experiment. 

Results: 

	Dry Gummy	Sugar Gummy	Water Gummy	Salty Gummy
Initial Weight(g)	2.22g	2.29g	2.26g	2.46g
Final Weight (g)	2.23g	4.30g	7.44g	3.91g
Difference	gain 0.01g	gain 2.01g	5.18g	1.45g

The water gummy gained the most weight.

Why? comparing sugar, salt and water molecules, water is the most smallest. Gummy bears have in fact tiny holes in them so the tiny water molecules can enter more than the sugar and salt molecules because of how big they are.
