Fun With Balloons

On the eve of my daughter’s 5th birthday, after ensuring the children were sound asleep, my husband and I blew up over 100 balloons.  We then left the balloons covering the floor of the kids’ bedroom for them to find when they awoke.  That started a year-long obsession with balloons.  From using them to count, to making a model of the solar system, to just playing around, we used balloons almost daily.

Parents: please remember balloons can be dangerous.  Children can choke or suffocate on uninflated or broken balloons.  Please keep uninflated balloons from children, and discard broken balloons at once. Please preview any website before allowing your child to view and please use your own judgement.  Links do not imply endorsement.

Nancy Willoughby graciously helped me assemble the below activities that will hopefully spark some wonderful fun and learning.

Before handing out the balloons ask your children some questions; explore their knowledge through oral language.  You are helping them make connections through your questioning.

  • What do you know about balloons?  Do you have anything to add?
  • Can you share a personal experience with balloons?
  • Describe a balloon.

Investigate vocabulary words with your students.  Ask them to define a word, if they aren’t familiar with the word then use a dictionary (or website) and look it up together.


  • Density
  • Circumference
  • Molecules
  • Hypothesis


Hand out two small balloons. Have two jars, cold water, and warm water on hand.

  1. What do you predict we will do with these balloons? Make predictions of what the experiments will ask us to do.
  2. Read the experiment:
  • Fill two small balloons with cold water, tie a tight knot to keep the water inside.
  • Now, fill one of the jars about halfway with warm water and the other one halfway with cold water.
  • Place a water-filled balloon into each jar.
  1. Make a hypothesis (educated guess) about what will happen & why you think it will happen
  2. Preform experiment
  3. What did happen? Do you know why it happened?
  4. If you repeated the experiment would you get the same results?
  5. Try it to check yourself

Ask your children if they know what the math vocabulary word circumference means. If not, read the book Sir Cumference and the Round Table before this experiment.

Hand out one balloons and a tailor’s measuring tape or a string and ruler.

  1. What do you predict we will do with these balloons? Make predictions of what the experiments will ask us to do.
  2. Read the experiment:
  • Blow up one balloon and tie it off.
  • Measure the circumference of the balloon, distance around the widest part.
  • Write down the measurement.
  • Now, with the help of an adult, dangle the balloon above a lit light bulb.  To thoroughly warm the balloon, you’ll need to rotate, or turn, the balloon above the bulb for two to three minutes.
  • Then, without removing the balloon from the heat source (you really need an extra hand here), measure the balloon’s circumference again.

3. Why are we using a light bulb? What does a light bulb give us in this experiment? Predict what you think will happen to the balloon.  Why do you think so?
4. Perform the experiment
5. Look at your data (your two measurements taken)
6. What happened to the balloon?  Why do you think it happened?

Creative Writing

Make up a story about a balloon.  Where does it go?  What does it see? What does it so? Who does it interact with?  Remember to have a beginning, middle, and end to your story.

If you have trouble creating a story about a balloon then draw a picture first, add some details to your picture.  Now explain your story to someone and tell them what a day in the life of your balloon was like.  For example, what did it do at morning, afternoon and in the evening.

Research Skills

Find the answers to these questions: Who invented the first rubber balloons?  What other kinds of balloons have been used?  How have balloons been used throughout history?

As you search for the answers you may start asking other questions: feel free to explore any questions the ones listed above are just to get you started.

Some relatively safe websites for researching balloons are listed below.  Parents, please preview any website before allowing your child to view and please use your own judgement.
