OSMISIS

Science Behind the Experiment

What is the scientific background of the Gummy Bear Osmosis Experiment?

The Gummy Bear Osmosis Experiment explores the scientific concept of osmosis, which is the movement of solvent molecules (usually water) through a semi-permeable membrane from an area of lower solute concentration to an area of higher solute concentration. Osmosis plays a crucial role in various biological processes, including the regulation of water balance in cells and living organisms.

​

What is a semi-permeable membrane, and how does it relate to the experiment?

A semi-permeable membrane is a barrier that allows certain molecules to pass through while blocking others based on their size, charge, or solubility. In the Gummy Bear Osmosis Experiment, the gummy bears act as the semi-permeable membrane. The gelatin in gummy bears allows water molecules to move in and out, while restricting larger solute molecules like salt.

​

What happens to the gummy bears during the experiment?

Over time, the gummy bears in the saltwater container will experience osmosis. Water molecules move from the gummy bear into the saltwater due to the higher solute concentration in the saltwater. As a result, the gummy bear shrinks or loses its size and volume.

​

What happens to the gummy bears in plain water?

The gummy bears in plain water also undergo osmosis, but in the opposite direction. Water molecules move into the gummy bear from the plain water, causing the gummy bear to swell or increase in size and volume.

​

What are the practical applications of understanding osmosis?

Understanding osmosis is vital in various scientific fields. In biology and physiology, osmosis plays a role in cell function and water balance within living organisms. In food science, osmosis is involved in processes like brining and pickling to preserve and flavor food items.

What You Will Learn

Are you ready to uncover the fascinating world of gummy bears and how they behave with water? In our Gummy Bear Osmosis Experiment, we'll discover a super cool process called osmosis. We'll place gummy bears in two different liquids - plain water and salty water - and see what happens!

Steps

Step 1

Gather the materials you'll need for the experiment. You'll need gummy bears, two small bowls or cups, and water.

Step 2

Place one gummy bear in each bowl or cup. Fill one bowl with plain water and the other with a solution of saltwater (mix water and salt together).

Step 3

Let the gummy bears sit in the water and saltwater for several hours or overnight. During this time, the gummy bears will absorb the water through osmosis.

Step 4

After the waiting period, take out the gummy bears and compare them. Observe any changes in size, texture, or appearance between the gummy bear in plain water and the one in saltwater. Discuss your findings and learn about osmosis!
