balloon yeast experiment
Kids will be amazed as they learn about the purpose of yeast with this simple yeast balloon experiment. This hands-on activity is perfect for students in kindergarten through 6th grade, making it a versatile choice for teachers and parents alike. Using just a few everyday materials, participants can visibly see the effects of yeast as it ferments sugar and produces carbon dioxide. This gas fills a balloon, allowing children to witness science in action right before their eyes!
All you need for this exciting experiment are some basic supplies: yeast, sugar, warm water, a balloon, and a bottle. As the yeast consumes the sugar, it begins to release carbon dioxide, which inflates the balloon. This not only captivates kids but also teaches them valuable lessons about fermentation and the science behind how yeast works in making bread rise.
Additionally, you can provide kids with a yeast balloon experiment worksheet that includes questions and activities related to their observations. This will reinforce their learning and encourage them to think critically about the experiment. Children can record their predictions, observations, and conclusions, transforming simple scientific exploration into a fun and educational experience.
Whether you’re a teacher planning a classroom project or a parent seeking an enjoyable activity to do at home, this yeast balloon experiment is a fantastic way to introduce fundamental scientific concepts. It’s not just about making balloons inflate — it’s about inspiring curiosity and a love for learning in young minds.

yeast balloon experiment worksheet
All you need are a few simple materials to try this science experiment:
- 1-2 clean, empty water bottles (16 oz. or smaller
- 1 packet of active dry yeast
- 1 teaspoon of sugar
- 1-2 balloon
- warm water
- worksheet
- pen
yeast balloon experiment
Fill the the empty bottle with about one inch of warm water. Add all of the yeast packet and gently swirl the bottle a few seconds. When yeast is cold or dry the micro organisms are resting. By adding warm water the yeast dissolves, it becomes active – it comes to life! Don’t bother looking for movement, yeast is a microscopic fungus organism.
Add the sugar and swirl it around some more. Like people, yeast needs energy (food) to be active, so we will give it sugar.
yeast sugar experiment
Blow up the balloon and release a few times to stretch it out then place the empty balloon over the neck of the bottle. The yeast is beginning to consume “eat” the sugar energy.
yeast and balloon experiment
Let the bottle sit in a warm place for about 20 minutes and observe what happens.
yeast and sugar balloon experiment
As the yeast feeds on the sugar, it bubble, grows, and expands. It also produces a gas called carbon dioxide. With no place to go but up, this gas slowly fills the balloon. A very similar process happens as bread rises. Carbon dioxide from yeast fills thousands of balloonlike bubbles in the dough.

Fill out your worksheet as you begin, watch the experiment, and draw conclusions to teach kids about the scientific method and record your findings.
yeast sugar balloon experiment
Try this experiment as explained above AND another one without the sugar. Ask the kid what they think will be different as a result.
