Gummy Bear Osmosis

 Aim: 

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

Method:

Equipment:

• Salt water (Sodium Chloride)
• Normal water
• Sugar Water(Sucrose)
• Gummy Bears
• 2x Petri Dishes
• Marker pen
• Electronic Scales

Instructions

1. Get your equipment
2. Wear Safety glasses
3. Using a marker pen write your name and the conditions and the weight of gummy bears.
4. Do the experiment.

Results: 

	Dry Gummy	Sugar Gummy	Water Gummy	Salty Gummy
Before Weight(g)	2.40g	2.32g	2.41g	2.40g
After Weight(g)	2.40g	4.36g	5.02	4.80g
Difference	gain 0	gain 2.04g	gain 2.59g	gain 2.40g

The water gummy gained the most weight because the molecules of the water are smaller than the salt and sugar water. In that case the gummy bear has small little holes around it. So the water can get through the water holes easier and it can get more water inside the gummy bear than the salt and sugar water. When the salt  and sugar water tries to go  inside the gummy bear's  small holes they all get stuck and they won't be able to fill upt the inside of the gummy bear in that case the gummy bear won't grow that big.
