Gummy Bear Osmosis

 Aim:

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

Method:

Equipment

• Salt Water/Sodium Chloride
• Normal Water
• Sugar Water/Sucrose
• Gummy Bears
• 2x Petri dishes
• Marker
• Electronic Scales 
• Safety Glasses

Instructions

1. Get your Equipment
2. Wear your safety glasses (IT IS A PRINCIPAL in the science lab).
3. With the marker, write your name and the conditions (dry, water, saltwater, sugar water) and the weight of gummy bears on the bottom of Petri dishes
4. Do the experiment.

Results:

	Dry Gummy	Sugar Gummy	Water Gummy	Salty Gummy
Initial Weight (g)	2.03	2.16	2.8	2.13
Final Weight (g)	2.13g	4.53	8.4	4.27
Difference	Gain 0.10g	Gain 2.37g	Gain 6.32g	Gain 2.14g

The water gummy weighs the most weight.

Why? The reason why is because gummy bears have small holes inside them. In water there are small molecules and Sugar/salt water have big molecules. Since gummy bears have quite small holes more little water molecules can come in and can expand. Sugar and salt water aren't able to do that because of their big molecules only a few could make it inside but they get clogged.

If not because the gummy bear absorbs the water.
