Science For Kids: Gummy Bear Osmosis Experiment

Osmosis Experiment

Introduction

The Gummy Bear osmosis experiment for kids is an excellent demonstration of osmosis. You can understand experimental design, mass, embedding maths, weight, and volume through this osmosis experiment.

What Is Osmosis?

Osmosis is the movement of water through a semipermeable membrane from an area high in water concentration to low in water concentration. The process balances the concentration on both sides of the solution. There are three types of osmosis conditions – hypertonic, hypotonic, isotonic.

Types Of Osmosis

In the hypertonic solution, there is more solute than water. In this case, the solvent moves into an area of lower concentration. It occurs when the semi-permeable membrane blocks some of the water and allows only solute molecules to move through it.

In the hypotonic solution, there is more water than solute. In this case, the solvent moves into an area of higher concentration. It occurs when the semi-permeable membrane allows some of the water to go through it but not all of it.

In an isotonic solution, there is an equal amount of solute and water content. Osmosis takes place in both directions equally, so no net movement of water or solute takes place.

What Are Gummy Bears?

Gummy Bears are bright and sugar-filled tasty candy, and they are not only delicious to eat but super fun for both kids and adults. A Gummy Bear is made of gelatin, water, and a sweetener like sugar or corn syrup. It starts as a liquid and then further cools down into an easy to chew solution. The chewiness of the gummy bear is majorly due to gelatin content.

What’s Unique About The Gummy Bears Osmosis Experiment? 

The gummy bear osmosis experiment is unique in its sense. You will observe most of the sugar candies dissolve in water, but gummy bears are an exception. They do not get dissolved in water and are thus the perfect pick for this experiment.

The reason gummy bears don’t dissolve in water is because of their gelatin content. When you make gummy bears, both water and gelatin are mixed and heated together. When it cools down, water starts to leave the candy. The candy then hardens and gets a bright texture and look.

Gummy Bear Osmosis Experiment – Details:

osmosis Experiment

The Gummy bear osmosis experiment is perfect for teaching children about this concept. It’s easy to set up, takes only a few minutes, and requires very little equipment.

Timeline:

It takes at least one hour to arrange all the material required to set up an experiment to demonstrate osmosis. The gummy bear experiment takes more than 48 hours. 

Materials Required :

  • Gummy Bear 
  • Glass for every liquid or solution used in the experiment 
  • 1 tbsp of sugar 
  • Salt – 1 tbsp
  • 1 tbsp baking soda 
  • Scale 
  • Calculator 
  • Kitchen ruler 
  • regular paper towels 
  • Stopwatch 
  • Experiment Sheet of gummy Bear 
  • A scientific table containing data of gummy bear 

How To Do The Gummy Bear Osmosis Experiment? 

Step 1: Fill every glass with sugar water, water and saltwater. 

Step 2: Label each of them.

Step 3: Fill the saltwater glass with half a cup of water. Mix salt (1 tbsp) in it and make sure that salt completely dissolves in the glass. 

Step 4: Similarly, do with sugar water and ensure that the sugar thoroughly mixes with water. 

Step 5: Do the same with baking soda glass as well. 

Step 6: Choose three gummy bears for each of the glasses. 

Step 7: Measure their height, width, and weight and write down the time of measurement. 

Step 8: Now, immerse each gummy bear into their respective glasses. 

Step 9: Wait for a minimum of half a day, i.e., 12 hours. 

Step 10: Separate the gummy bear post 12 hours and make the exact measurements and note them. 

Step 11: Immerse the gummy bears again in their respective solution. 

Step 12: Post 24 hours, repeat the exact measurements and then immerse the gummy bears again. 

Step 13: Again, repeat the same process post two days, i.e., 48 hours. 

The Result

As per the final result, you can see that all three gummy bears have expanded in size. Slight expansion is witnessed just after 12 hours only. And it continues with each measurement.

process of osmosis

Gummy bears have such a surface area that allows some particles to pass through whereas some others can’t pass through. It has small gaps in it so that charged and minute matters like water can enter, but any other large particles are unable to enter. 

The core principle of the gummy bear experiment for kids is that when the experiment is started, the gummy bear has more gelatin and less water content and thus, it is highly chewy. But as the experiment progresses, the attractive gummy candy bear has more water and less gelatin content, and therefore it becomes softer and softer similar to a sponge. After a while, it gets dissolved in water.

  2. Glass for every liquid or solution used in the experiment 
  3. 1 tbsp of sugar 
  4. Salt – 1 tbsp
  5. 1 tbsp baking soda

How to do the Gummy Bear Experiment for Kids? 

Step 1.

Fill every glass with sugar water, water and saltwater. 

Step 2.

Label each of them.

Step 3.

Fill the saltwater glass with half a cup of water. Mix salt (1tbsp) in it and make sure that salt is completely dissolved in the glass. 

Step 4.

Similarly, do with sugar water and make sure that the sugar is thoroughly mixed with water. 

Step 5.

Do the same with baking soda glass as well. 

Step 6.

Choose three gummy bears for each of the glasses. 

Step 7.

Measure their height, width and weight and write down the time of measurement. 

Step 8.

Now, immerse each gummy bear into their respective glasses. 

Step 9.

Wait for a minimum of half a day, i.e. 12 hours. 

Step 10.

Separate the gummy bear post 12 hours and make the same measurements and note them. 

Step 11.

Immerse the gummy bears again in their respective solution. 

Step 12.

Post 24 hours repeat the same measurements and then immerse the gummy bears back again. 

Step 13.

Again repeat the same process post two days, i.e. 48 hours.

The Explanation For The Osmosis Experiment: 

The gummy bears swell in size due to osmosis. Water flows down from the glass to the gummy bears, and thus it expands in size.

Now, let’s understand the reason behind the results of the gummy bear osmosis experiment for kids. The gummy bears have a surface area that allows some particles to pass through, whereas others can’t. It has small gaps so that charged and minute matters like water can enter, but any other large particles cannot enter. This is the semi-permeable membrane required for osmosis.

When you immerse a gummy bear in water, the water acts as a solute. At the same time, the water molecules act as a solvent. This is when the osmosis begins. We know osmosis occurs when water flows from a high concentration to a low concentration. The gummy bear has zero water content, and thus when you put it into the water, the water flows into the gummy bear through the osmosis process. 

The Core Principle Of The Osmosis Experiment: 

When the osmosis experiment starts, the gummy bear has more gelatin and less water content, and thus, it is highly chewy. But as the experiment progresses, the gummy bear gains more water, making it softer and softer like a sponge. After a while, it dissolves in water. 

Takeaway:

Now you know why when you buy a bag of gummy bears in a store, they are small and hard like rocks, yet when left overnight in a cup with some water, they soak up all the water and grow into big plump bears!

Overall, the gummy bear osmosis experiment is such fun yet simple! Science experiments like gummy bear osmosis are the best way to make your kids understand scientific concepts that appear dull to them.
