Gummy Bear Osmosis

 Aim: I want to find what happens to Gummy Bears when we put them into different solutions.

Prediction: I predict that they will dissolve into the solutions. I also predict that the salt water will make the gummy bear smaller 

Method:

Equipment:

4x Gummy Bears

2x petri Dishes

paper towels

marker pen

water

sugar water

salt water

electronic balance

Beaker

measuring cylinder

Steps:

1. get your equipment

2. Put 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. Weigh the gummy bear and write the weight on the petri dish 

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

	Dry	Water	saltwater	Sugar water
Initial weight of gummy bear	5.81g	5.36g	5.73g	5.45g
Final weight	5.70g	6.52g	6.22g	6.05g
Weight difference	Lost 0.11g	Gain 1.6g	Gain 1.16g	Gain 0.60g
Initial volume		40ml	40ml	40ml
Final volume		0ml	10ml	7ml

Volume Difference

Lost 40ml

Lost 30ml

Lost 33ml

Discussion 
osmosis 

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

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

- The sugar water diffused faster than the salt water.

Diffusion meaning 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.
