Gummy Bear Osmosis

Aim:

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

Method:

Equipment:

• Salt water (Sodium Chloride)
• Normal water
• Sugar water (Sucrose)
• Gummy bears
• 2x Petri dishes
• Marker pen
• Electronic Scales
• Safety Glasses

Instructions:

1. Get your Equipment
2. Put on Safety Glasses
3. Using a marker pen write your name and the conditions and the weight of gummy bear
4. Do the experiment

Results:

The water gummy bear gained the most weight

Why? 

There are little holes in gummy bears and since water molecules are small and sugar/salt molecules are big the water molecules and rush into the gummy bear while sugar/salt get blocked while trying to get into the gummy. Since the water molecules are small they don't get blocked so the gummy bear is absorbing the water molecules and it grows.
