<p><center>Hello friends of @steemit, the education of our children is of the utmost importance, for us as parents it is our duty to seek the strategies and tools necessary to impart a quality education, the science can be overwhelming and even boring for the little ones if not It is taught in a way that awakens the interest and curiosity of children, that is why today I bring you some information that can be very useful and can be put into practice in their homes.</center></p>
<center> Home Experiments can become your best ally, they offer you a universe of possibilities and knowledge that you can teach your children, to teach your children science you do not need a laboratory, or complicated materials, with basic elements that we get in our we can achieve it.</center></p>

<center>Today we will study what the Indicators are and how they react when mixed with other substances!</center></p>
<h1><center>So let's go with the fun, let's start with the experiment:</center></h1>
<center>Indicator natural acid base with hibiscus flower.</center></h1>
An indicator is a substance that changes color as it is mixed with an acid or a base. There are many flowers, fruits and leaves that can be used to make homemade natural indicators and the red hibiscus flower works wonders. Hibiscus is a shrub that does not tolerate frost, so you will only find it in warm areas.
If you do not have one near you can also do the experiment because many of the red fruit infusions sold in the supermarket contain hibiscus flower.

At home we can find many acids and bases with which to experiment. Vinegar, orange and lemon juice, carbonated drinks, yogurts, are all acidic. Baking soda, soap and cleaning products are bases. Pure water is neutral, it is neither acidic nor basic, however that of the tap can be slightly acidic or slightly basic. To measure the acidity of a solution, the chemists use the pH scale, which goes from 0 to 14. The distilled water has a pH = 7, which is the value that is in the middle. The acids have a pH between 0 and 7, while the pH of the bases is between 7 and 14.
When an acid is mixed with a base, both are neutralized, that is, they cease to be acids or bases and water and a salt are formed. In some cases carbon dioxide, CO2 is also released.
<h1>Materials:</h1>
<ul>
<li> Red hibiscus flowers, fresh or infused.</li>
</ul>
<ul>
<li> Water.</li>
</ul>
<ul>
<li> Vinegar or lemon juice (weak acids).</li>
</ul>
<ul>
<li> Baking soda (weak base).</li>
</ul>
<ul>
<li>3 containers, 3 spoons and three glasses.</li>
</ul>
<ul>
<li> Both the acids and the bases Strong are corrosive to the skin and eyes so they should not be used without adequate protective measures.</li>
</ul>

<h1>Process:</h1>
<ul>
<li> Mix two teaspoons of baking soda in half a glass of water.</li>
</ul>
<ul>
<li> Prepare also half a glass of water and half a glass of vinegar.</li>
</ul>
<ul>
<li> Chop the petals of the hibiscus flowers and put them in three containers.</li>
</ul>

<ul>
<li>In one of the containers add water, in another the vinegar and in another the bicarbonate.</li>
</ul>

<ul>
<li>Remove with the spoons and observe the color changes, orange for the vinegar and dark purple for the bicarbonate. With water its color is light blue.</li>
</ul>

<center>Orange acid, light blue water and purple base. Removing with the spoon we will obtain a more intense color.</center></p>
<h1>What has happened?</h1>
The hibiscus flower contains some pigments called anthocyanins that change color when in contact with acids and bases. It acquires a reddish color in the presence of a weak acid such as vinegar and purple in contact with a weak base such as sodium bicarbonate.

<center><strong><em>Children love to do experiments. With them, while having fun, they learn and ask questions about the world around them. Among its many benefits, scientific exploration feeds the child's natural curiosity, fosters his interest in science, stimulates reasoning and logic, improves his ability to solve problems, increases his self-esteem and prepares them to understand more complicated scientific concepts in the future.
To enjoy science is not necessary to have a laboratory, you will be surprised at the amount of experiments that can be done with a few homemade materials. So do not wait any longer, get down to work and have fun with your children or students.</em></strong></center><center><strong><em>I hope that this article has been of your interest and help and I hope you in my next post.</em></strong></center><center></center><center><img class="alignnone size-medium wp-image-11" src="http://lasocia.vornix.blog/wp-content/uploads/2018/07/steemieducation-300x122.png" alt="" width="300" height="122" /><br/></center><center></center><center></center><center><img class="alignnone size-medium wp-image-12" src="http://lasocia.vornix.blog/wp-content/uploads/2018/07/edu-venezuela-300x122.png" alt="" width="300" height="122" /><br/></center><center></center><center></center><center>Pages reference:</center><center></center><center></center><a href="https://www.monografias.com/...indicadores-acido/obtencion-indicadores-acido.shtml">https://www.monografias.com/...indicadores-acido/obtencion-indicadores-acido.shtml</a>
