3 scientific experiments for children

Aside from being educational, science can be fun. If we think about it, we realize that children behave like scientists: they consider a hypothesis and test it through trial error. It has nothing to do with finding the next great scientist among the smallest children – while this might happen – but simply encouraging curiosity and inquisitiveness by way of simple games that stray from the routine and catch them by surprise

An increasing number of schools and play centres are looking to actively teach their children through simple tests and experiments carried out in a matter of minutes without any risk to them.   

This is precisely because they make use of daily objects or ingredients, and there are numerous experiments for children which can be done at home. While the only risk is that of cleaning up after the experiment, it is recommended that the experiment is carried out under adult supervision. 

Parental supervision or that of any other adult is not just a question of safety. When they are joined during the experiment, they have the opportunity to resolve doubts, be assessed in the achievement a positive result, learn to work as a team, and accept that the ideas of others can be just as positive as their own. 

In fact, during the learning process they must work with several classmates on multiple occasions. The goal is for the children to accept this idea, so it is easier for them to become accustomed to other environments and ways of working. 

Here we have proposed three ideas to start your children on the path to the wonderful world of science. If they like them, have fun, and are involved, you will see that it is only a matter of time when they begin to propose their own experiments and to take a more active role in the process.



Just like many adults, children are always surprised when they see at the rainbow, often when travelling by car or when on a walk after a sudden summer storm. 

In laymen’s terms, this optical phenomenon consists of the appearance of a multicoloured arch in the sky which is produced when rays of sunlight pass through the drops water. 

Another piece of information. Despite that several scientists had worked on this idea, Isaac Newton was the first one to understand this phenomenon thanks to his tests on light decomposition. 

 To witness this phenomenon at home, we only need two glasses of water (one large and one small), food colouring (red, blue and yellow), honey, blue dish soap, sunflower oil, alcohol and a small spoon.  



Before conducting this experiment, we propose asking your child if it is possible to inflate a balloon without blowing into it and, of course, without the use of a hand pump. What do they think?

All that’s needed is to show them the ingredients: 3 small empty water bottles, 3 balloons, baking soda, a plastic funnel and vinegar. 

With these ingredients and by following the instructions found in this video, they will be surprised when the 3 balloons begin to inflate based on simple science. 



And lastly, an experiment designed at creating a lamp of the most state of the art variety. In fact, it is so practical that it does not require a bulb or an electrical connection.

The components we will need are: a glass bottle with a wide neck, sunflower oil, a glass of water, a plastic funnel, effervescent tablets, and food colouring. 

As the video reminds us, the more pills we use, the more bubbles that will appear in our wonderful lamp.
