  safety rules: 

     1.  Do not touch any equipment, chemicals, or  other materials in the laboratory area until you  are instructed to do so; 

   2.Work areas should be kept clean and tidy at all      times; 
  3. Never return unused chemicals to their original    container.

Additional information:

•  Effects  

Some antacids also coat the surface of the esophagus with a protective barrier against stomach acid. Sometimes medication can produce a gel on the stomach’s surface, which helps stop acid leaking into the esophagus and causing acid reflux Acid reflux is when the person has an unpleasant taste in mouth that is caused by stomach acid coming back up into the mouth.

• Who cannot take antacids?

 Antacids are not suitable for everyone. For example, doctors do not recommend antacids to people with certain health conditions, such as kidney disease. Person cannot take antacid while being treated for another condition.

     Definition of “Element”

Element is the building block of all matter on Earth. It is a pure substance. Elements can be separated into anything simpler physically or by chemical reactions. They are listed in the Periodic Table of Elements. 

WHAT IS THE PERIODIC TABLE?

The Periodic Table is a graph that lists all the known chemical elements. There are exactly 118 elements in the table. Again, elements are the basic building blocks of all matter.

CHEMICAL SYMBOLS

Each element has a chemical symbol. These are one or two letters, and short way of representing that element. For example, the chemical symbol for Oxygen is O and the symbol for Iron is Fe.

The elements are listed in the Periodic table in order of increasing Atomic Number – the number shown upon element. Elements can be Metallic and Non-metallic. Metallic elements are about 2/3 of the all elements and are found on the left of the Periodic table. Non-metallic elements are about 1/3 of the elements and are found on the upper right of the Periodic table.

          Hi everybody! I want to share with you some of my experiments.These chemistry experiments are about an acid and the base.These experiments are specially designed for children around 10 years  old. They are in 5th grade and as I know in most of the countries, school program starts studying chemistry at this age. The first topic, they are studying is about an acid and the base. When I was of there age, it was difficult to understand the subject without any experiments. To avoid the same problem, I have done some experiments which can help them to understand the chemistry better. The experiments are not very difficult and dangerous, instead they are very interesting and useful for them. Therefore, ordinary teachers can hold the experiment for kids. 

 I hope you will like it!
