Gummy Bear Osmosis (Science)

Kamusta everyone,

For today's blog I will be sharing you our gummy bear experiments. We went through everything we need to know before doing this experiment, the methods which is the equipment and instructions. 

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 pen
• Electronic scales

Instructions: 

1. Get your equipment
2. Wear your safety glasses
3. With a marker pen, write your name and the conditions (dry, water, salt water, sugar water) and the weight of gummy bear 
4. Do the experiment

-Result-

Before:

After: 

	Dry Gummy	Sugar Gummy	Water Gummy	Salty Gummy
Initial Weight(g):	2.45g	2.21g	2.23g	2.22g
Final Weight(g):	2.43g	5.23g	7.45g	4.07g
Difference:	.2g -	gain 3.02g	gain 5.22g	gain 1.85g

It thicken it size and volume since the water is entering. The gummy bear has little holes inside. There is a water molecules which is smaller, and sugar/salt molecules are bigger. There are much more water molecules (small) that could get inside the hole and less than sugar/salt molecules that could get in because of its size, that's why the water gummy bear is bigger than before. 

Thank you for reading my blog, I hope you learnt something new and I'll see you on my next post, goodbye :>
