 Gummy Bear osmosis

Aim 

I want to find out what happens to Gummy Bears when they are put into different solutions.

Prediction: I predict that they will dissolve into the solutions. 

Method: get your equipment and put on your safety glasses, using the marker pen.write the name of the condition on the petri dish.DRY, WATER, SALTWATER, SUGAR WATER.weigh gummy bear and write the weigh on the the petri dish measure 40ml of the solution and pour it into the petri dish. 

equipment:

1. 4x gummy bears

2. 2x petri dishes

3. paper towels

4. marker pen

5. water

6. sugar water

7. salt water

8. electronic balance

9. beaker

10. measuring cylinder 

step 1. get your equipment.

step 2. put on your safety glasses

step 3. using the marker pen.write the name of the condition on the petri dish.DRY, WATER, SALTWATER, SUGAR WATER

step 4. weigh gummy bear and write the weigh on the the petri dish.

step 5. measure 40ml of the solution and pour it into the 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

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 is the movement of a substance from an area of high concentration to an area of low concentration.Diffusion happens in liquid and gases because their particles move randomly from place to place.Diffusion is an important process for living things.
