A simple experiment with a ball and a candle for children or how to get a child interested in learning physics

click fraud protection

Physics is not only boring theoretical calculations and complex formulas, it is also simple and very exciting experiments. But children are often very difficult to get to learn this really interesting science.

In this material, I suggest you conduct a simple experiment that will be of interest to your child (and some adults will also be interested). So let's go.

A simple experiment with a ball and a candle for children or how to get a child interested in learning physics

What is needed to conduct the experiment

In order to successfully conduct an experiment, you and I need the following set:

  1. A pair of regular balloons.
  2. Matches or a lighter.
  3. Candle (absolutely any).
  4. Plain water.

Everything. As you can see, the set is not very difficult, which means that absolutely anyone can repeat it (there would be a desire).

So, after you have prepared everything, you need to inflate one balloon with air (do not inflate much), and pour a little ordinary water into the second and only then inflate and tie it a little. Then light a candle and get ready for the experiment.

Attention. Be sure to warn a small child that the balloon will burst and there will be a loud sound. After all, we do not need the child to be frightened, our task is to interest him.

You can watch the experiment in the video below.

Explanation of the experiment

So, the experiment was successful, and the child asks: "Dad (mom), why is this happening?" And the thing is that in the first the case (when we heated the ball with air) the flame of the candle warmed up the rubber so much that it quickly collapsed and the ball burst.

And in the second case, the water in the ball is an excellent conductor of heat, and it takes heat from that area. rubber (which you heat up) and thus prevents the flame from destroying the rubber, and the ball remains intact and unharmed.

With a special desire, you can even boil water in this way, but, of course, you will not be able to drink it.

Such a simple and illustrative experiment may well awaken a child's interest in studying such an amazing science as Physics.
