Balloons are fun and kids love to use them for all kinds of creative games and activities, so what else do balloons do? Today, the alpha science classroom unveils the properties of balloons made of different materials through Stretchy Balloon Science experimental activities for children to learn the mystery of elasticity in children's physical science experiments and enjoy the fun that comes with special kid's science experimental activities.

  • Several new balloons, all the same size and material

  • Permanent marker

  • Freezer

  • Skewer

  • Lip balm or petroleum jelly

Alpha Science Classroom: Bouncy Balloon Science Experiment Procedure

Step 1: The children take a room temperature balloon and blow it into it. How hard is it to blow into an airball? Blow into the balloon a few more times. Is it getting easier or harder to blow air into the balloon? Why is this?

Step 2: Children let the air out of the balloon and take some deep breaths before continuing. Take a balloon out of the refrigerator and repeat the first three steps with this balloon. How hard is it to blow up a cold balloon compared to a balloon at room temperature?

Step 3: Children make fair comparison by repeating the previous steps, now testing another cold balloon first and a room temperature balloon last. Did your results change? Why would one be harder than the other?

Step 4: Children, take out one of the room temperature balloons you just used and inflate it until you are worried that it will burst if you blow into it again. Then let the air out.

Step 5: Children place a new balloon next to the other two used room temperature balloons. In what ways do these three air balloons look similar and different? Rub some lip balm on the skewer, starting at the top.

Step 6: The children blow up one of the balloons (anyone will do) until it is about two-thirds full and tie it in a knot so that the air is trapped. What do you think happens when we poke the balloon with the kebab?

Step 7: Children look at the balloon you blew up. Where would you poke the kebab skewer into the balloon to quickly blow up the balloon? Why did you choose that spot? Can you find a place where you might poke a kebab skewer into a balloon without bursting it?

Step 8: The children poke the balloon and let it pop. Did it pop? What do you think caused the loud sound of the balloon popping?

Step 9: Children inflate another balloon until it is about two-thirds full. Tie it in a knot and check it. If you wanted to poke the skewer into this balloon without popping it, where would you poke it?

Try it. Did you succeed?

If not, try with another balloon. Notice how the rubber near the knot or at the top looks darker and thicker. These are signs that the rubber can still stretch there. Try a few more times until you succeed in poking your skewer into the balloon without popping it. Why do you think the skewer can get into the balloon in these places without popping it?

Alpha Science Classroom: Bouncing Balloon Science Experiment, Science Principles

Alpha science classroom tells children if a cold balloon requires more effort to blow up compared to a balloon at room temperature? Does your balloon burst when you poke it where it is stretched tight?

The particles in cold material move and wiggle less and can grip each other more easily. Therefore, a cold balloon resists being stretched more than a hot one. You think of this as trying harder to blow up a cold balloon. You may have noticed that this resistance disappears as the balloon gets warmer.

When you try to poke a taut part of the balloon, it may burst. Think of a rubber band that has been stretched. When you cut it down the middle, the ends fold back. In a similar way, the small hole in the taut surface causes part of the surface to spring back, pulling the material back. This pull tears the surface of the balloon apart. The air in the balloon rushes out, creating a shock wave, and you hear a loud bang.

Well, children through this fun Bouncy Balloon Science Experiment, the different materials and properties of balloons have a certain understanding of the hope that this fun children's physical science experiment activities to help children understand the simplest physics knowledge while getting kid's science experiments activities fun, to help children learn and grow, want to learn more about science, just follow us!

alpha science toys also for children, prepared a magical children's physical science experiment kit, so that children in the exploration of scientific knowledge at the same time, enjoy the fun brought by science, grow up to be the happiest scientists.
