Gummy Bear Osmosis

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

Prediction: They will dissolve into the solution.

Equipment:

• 4 gummy bears of the same colour
• 2 petri dishes
• 1 marker pen
• water
• sugar water
• salt water
• electronic balance
• beaker
• measuring cylinder

Instructions:

1. Get your equipment.

2. Put on your safety glasses.

3. Using the marker pen, write the name of the condition on the petri dish. Dry, water, salt water, sugar water.

4. Weight the gummy bear and write the weight on the petri dish.

5. Measure 40mL of the solution and pour it into the petri dish.

Discussion:

Osmosis:

1. The normal water was transferred into the gummy bear the most.

2. The dry gummy bear lost 0.11 grams over a week.

3. The sugar water diffused faster than the salt water

Diffusion:

Diffusion is the movement of a substance from an area of high concentration to an area of low concentration. Diffusion happens in liquids and gases because their particles move randomly from place to place. Diffusion is an important process for living things; it is how substances move in and out of cells.
