EXPERIMENTS FOR CHILDREN

Welcome to this website dedicated to the experiments for children, homemade experiments and to the science. In this website we want to tell you in a simple way how to apply some of the best known principles of physics and chemistry. The experiments you will find are easy experiments for children, whether they are experiments for primary school children, science projects for primary school children, school science projects or simply home experiments for children. Use the search engine on the left to select the experiments according to age or topic you are most interested in.

• Category: Chemistry
• Thematic Area: Soap making
• Main products used: Ethanol, Vegetable Glycerin

Calcium Chloride Silicate Crystallisation - Jardín Químico

This experiment shows how calcium silicate crystals grow almost spontaneously and immediately in a solution of sodium silicate in water.

• Category: Chemistry
• Thematic Area:

Fluorescent Tonic

In this experiment we show the fluorescence emitted by common tonic, specifically Schweppes brand tonic. This tonic contains a natural fluorescent component called quinine.

• Category: Chemistry

• Main products used:

Venturi Effect Demonstration Experiment

This experiment was recorded at the Alcobendas Science Museum. In it you can experience the overpressure produced by the Venturi effect by widening the air duct section.

• Category: Physics
• Thematic Area: Fluid Mechanics
• Main products used:

How Planes Fly Experiment. Bernoulli's Principle

In this experiment, carried out at the Alcobendas Science Museum, we are going to see how the lift of an aeroplane wing is produced following Bernoulli's principle.

• Category: Physics
• Thematic Area: Fluid Mechanics
• Main products used:

Cloud Slime or Snow Slime

In this experiment we make an extra flexible slime, fluffy slime or cloud slime. Once the slime is finished, artificial snow powder or sodium polyacrylate is added to give it extra flexibility.

• Category: Chemistry
• Thematic Area: Polymers
• Main products used: Borax, Sodium Polyacrylate

How to make a Slime

Different ways to make a slime, undoubtedly one of the most widespread experiments nowadays. Borax, Glue, PVA, Fluffy Slime, Fluorescent. In this post we tell you about the different ways to make a slime.

• Category: Chemistry
• Thematic Area: Polymers
• Main products used: Borax, Sodium Polyacrylate

Sugar Carbonisation with Sulphuric Acid

This experiment is a very striking experiment where you can see a sugar combustion reaction, produced by the dehydration of sugar through the action of sulphuric acid.

• Category: Chemistry
• Thematic Area: Strong Reactions
• Main products used: Sulphuric Acid

Decomposition Reaction: Oxygenated Water Decomposition

In this experiment we can see the rapid and violent decomposition of hydrogen peroxide into oxygen and water.

• Category: Chemistry
• Thematic Area: Strong Reactions
• Main products used: Hydrogen Peroxide

Sodium Metal Reaction in Water Experiment

In this experiment you can see the instantaneous and violent reaction of sodium in water.

• Category: Chemistry
• Thematic Area: Redox Reaction, Strong Reactions
• Main products used:

Experiment: The game of atoms I

Small game to begin to learn about the structure of the atom. Protons, electrons and neutrons, as well as their atomic distribution.

• Category:

• Main products used:

Making a Slime with Polyvinyl Alcohol (PVA) and Borax

In this experiment we make a slime using the original slime materials: polyvinyl alcohol and borax. We also make it in a fluorescent colour to make it different and more fun.

• Category: Chemistry
• Thematic Area: Fluorescence, Polymers
• Main products used: Polyvinyl Alcohol, Borax, Sodium Fluorescein, Rhodamine

HOMEMADE EXPERIMENTS

The experiments you find on this page are homemade experiments. Experiments that, although you need some materials to carry them out (each experiment is indicated), can be carried out at home in a simple way. They are homemade experiments for childrenwhich will also be of interest to adults. They can also be used as school experiments.

TOPICS COVERED BY THE CHILDREN'S EXPERIMENTS

In each of the experiments, whether they are chemistry experiments or physics experiments, you will find a link to the theoretical basis that explains the experiment in question. You will find processes, chemical reactions and principles of physics such as Newton's Lawswhich we encounter on a daily basis in our daily lives. Oxidation reactions, pH and its measurement, the atomThese are some of the principles that you can apply in your daily life.

WHO WE ARE

This website is a private project, for the diffusion of science among adults and children. Within the same group you can find the website of Alquera.com  y Nieveartificial.es. You can follow our posts from our Facebook page, Instagram page o Youtube.
