

As of now, our country is in the midst of a great crisis in our economy. Our environment nowadays is also being destroyed due to improper garbage disposal. 



The researchers noticed that at school, teachers requires commercial chalk used in boards. Chalk is a soft, white, porous sedimentary rock, a form of limestone composed of the mineral calcite. It forms under relatively deep marine conditions. Chalk can also refer to other compounds including magnesium silicate and calcium sulfate. There is no assurance that we can have continuous supply of a 







Statement of the Problem

The study aims to answer the following questions:



1. Will the eggshell be an effective substitute for chalk? cchalk? halk? 2.Are there any similarities s imilarities between the composition of an eggshell and a chalk? 3. Does the flour and starch affect the effectiveness of eggshell as a substitute for chalk? 

Significance Significance of the Study





The importance of this study is, it can give benefits, especially to the poor ones or those who can’t afford to manufacture chalk. The poor ones could also have their own business by simply following the instructions in making “eggshell chalk” and to save money. 



The purpose of this study is to try and discover other methods on how to make and provide cheaper chalk for the needs of people especially the teachers, who highly use commercial chalks to write on the boards for their lectures in schools. 







Scope Scope and Delimitation



The study is limited on finding the effectiveness of chicken eggshell mixed with either flour or starch as a substitute for commercial chalk. 

1. Chalk - a soft, white, or gray fine-grained sedimentary rock originally formed under the sea. 2. Eggshell - the brittle protective covering of the egg of a bird, or other similar tough covering of the eggs of animals such as crocodiles and turtles. 3.Flour – a powder made by grinding the edible parts of cereal 

4. Calcium Carbonate – a white crystalline solid that is one of o f the of most common natural substances found in chalk, limestones, marble, eggshells, and bones. 5. Pulverize – to crush or grind something into powder or dust. 6. Starch – a natural substance composed of chains of glucose units, made by plants and providing a major energy source for animals. The two main components of starch are amylose and amylopectin. 7. Effectiveness – the ability to do something well or achieve a desired result without wasted energy or effort. 8. Eggshell Chalk – a chalk made up of powdered eggshell mixed 
