Simple Science Experiment for Kids- Growing a gummy bear

Growing A Gummy Bear

The kids love questioning why things occur I have found that letting them experiment with their question is a great way for them to have fun and answer their questions. This week’s science experiment we will be growing a gummy bear. It is a simple and fun way to learn about the process of osmosis. Let’s get started.

Comments on the video:

We got a new background. Did you notice it was kind of messed up at the beginning of the video? Oh well! Use cold water not hot or warm. Don’t leave the gummy bear in the water too long, overnight is fine but do it in the evening then not bright and early in the morning and then let it wait 24 hours, 8-16 hours is fine. They will dissolve if left too long, or if it gets to wet where you touch them, they will break apart. Although they do grow pretty big the longer they are left to absorb the water. Here are the details so you can do it yourself!

What you will need:

  • water
  • small cup or bowl
  • gummy bear candy
  • ruler
  • pencil
  • journal
  • crayons


Result Timing: Overnight


What to do:

    1. First, in your journal draw an outline of your gummy bear.
    2. Next measure your gummy bear with a ruler the length from top to bottom and the width from side to side.
    3. Then label this information BEFORE. Write down any observations and your predictions or hypothesis what you think will happen when you leave a gummy bear in water overnight.
    4. Next, you will put the gummy bear in the cup or bowl and cover it just enough with water.
    5. Let the gummy near soak in the water overnight.
    6. Check the gummy bear in the morning.
    7. Draw an outline of your gummy bear now and measure it again.
    8. Record your measurements in your journal and write down any observations.
    9. Label this AFTER.
    10. Check if your prediction was correct.

How it works

The gummy bear grows bigger because it soaks up the water. This process is called osmosis. Water naturally moves from areas that have a high water content to areas nearby that have less water. Osmosis tries to balance “wetter” area with “drier” ones so that there isn’t as much of a difference in the water content between the two areas. A gummy bear contains very little water. When you put it into a bowl of water, the “dry” gummy bear attracts water and grows at it holds more and more water. Try this experiment with different liquids and compare the results, try salt water, sugar water, vinegar, milk, and baking soda water.
