Gummy Bear Osmosis

 Mhoro Amazing Readers,

Today I'm going to be sharing with you a blog post about Gummy Bear Osmosis. This is another SCIENCE EXPERIMENT in our Science class.We had to be in a group of 6. The people I was with were Divine(AKA Me),Michaela,Tiana,Letitia-Ann,Olivia and Shakala. We are also learning about the meaning of Diffusion in liquids.We are also learning about Osmosis.Here are the steps

Aim:

I want to find out what happens to Gummy Bears when we put them into different solution.

Predictions:I predict  that they will dissolve

Method:

Equipment

• 4x Gummy Bears of the same colour
• 2x petri dishes
• paper towels
• 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, SALTWATER,  SUGAR WATER.
4. Weigh the Gummy Bear and write the weight on the petri dish.
5. Measure 40mL of solution and pour it into the petri dish.

Results:

	Dry	Water	Salt Water	Sugar Water
Initial weight of Gummy Bear	5.81g	5.36g	5.73g	5.45g
Final Weight of Gummy Bear	5.70g	6.52g	6.22g	6.05g
Weight Difference	Lost 0.11g	Gain 1.16g	Gain 0.49g	Gain 0.60g
Initial Volume		40mL	40mL	40mL
Final Volume		0mL	10mL	7mL
Volume Difference		Lost 40mL	Lost 30mL	Lost 30mL

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 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.
