Gummy Bear Osmosis

 Aim:

I want to find out what happen to Gummy bears when we put them into different solutions.

Prediction :

I predict that the gummy bears we dissolved and it's going to grow. Plus the colour we won't mix like the Skittles.

Method :

Equipment :    

• 4x Gummy Bears of the same colour 
• 2x petri dishes 
• Paper towel
• Marker 
• 3x solutions( water, sugar water and salt water)
• Electronic balance 
• Beaker
• Measuring cylinder 
• Safety Glasses  

instructions:

1.  Gather you equipment 
2. Put you safety glasses
3. Using the marker pen write the name of the condition on the petri dish. ( DRY, WATER, SALTWATER AND SUGAR WATER. 
4. Weight the Gummy Bear and write the weight on the petri dish.
5. Measure the 40 mL of the solutions and pour into the petri dish.

Result :

Last Result :

	Dry	Water	Salt Water	Sugar Water
Inital weight	5.60g	5.51g	5.51g	5.51g
final weight		4.28g	5.25g	6.40g
loss weight		1.23g	0.26 g	1.2g
inital volume		40ml	40ml	40ml
final volume
water loss

What is Osmosis ?

a process by which molecules of a solvent tend to pass through a semipermeable membrane from a less concentrated solution into a more concentrated one.
