Gummy bear osmosis

Aim:

I want to find out what happens to gummy bears when we put them into  different solutions.

Prediction:

I predict that the gummy bears will grow bit by bit.

I predict that the gummy bears will dissolve into the solutions.

Method:

Equipment

• You will need 4x gummy bears of the same colour
• You  will need 2x petri dishes
• Taper towel 2x
• Marker
• Water
• Sugar water
• Salt water
• Electronic balance
• beaker
• Measuring cylinder
• safety glasses

Instructions:

1. Gather your equipment.
2. Put on your safety glasses.
3. Using the marker, write the name of the condition on the petri dish. DRY,WATER,SALT WATER,SUGAR WATER.
4. Weigh the gummy bear and write the weight on the petri dish.
5. Measure 40mL of the solution and pour it into the petri dish.

What is osmosis

Osmosis, the spontaneous passage or diffusion of water or other solvents through a semipermeable membrane (one that blocks the passage of dissolved substances—i.e., solutes).
