Production of Chalk from Eggshells Essay Example

I The chalk is a white porous sedimentary rock, a form of sedimentary rock composed of mineral calcite. It forms under reasonably deep marine conditions from the gradual accumulation of minute calcite plates shed belonging to the division of haptophytes.

They function as a special calcium carbonate. Eggshell is another object that has the presence of calcium carbonate. It is used by animals to store their young in it and protect it. Some birds like the chicken force the eggs out while some wait for some time until it is out. The chicken egg is usually made as human food, and the others are left alone to give birth to life. Gathering Information Phase II while some wait for some time until it is out. The chicken egg is usually made as human food, and the others are left alone to give birth to life.

The study used these materials to conduct the experiment. A mixing bowl to mix the water, powdered eggshells and flour together, a sheet of hard paper to mold the chalk to a cylindrical shape, mortar and pestle to crush the eggshells into fine powder , weighing scale to measure the amount of grams of eggshell powder and flour, a beaker to contain the amount of hot water, a teaspoon to measure the amount of hot water to be added on the mixture. Instrumentation Phase III Get used eggshells and flour to produce the chalk. First, clean the ggshells, washed them and peeled of the skin.

Then grind five pieces of eggshells using the mortar and pestle until they turn to very fine powder. Then get 4o grams

of eggshells powder and 20 grams of flour and combined them in a bowl. Then heat a water in a beaker and add four teaspoons of hot water to the mixture of eggshell powder and flour. Mix together the mixture using the spoon until it becomes sticky and a little dry. Then move the mixture on a hard paper and mold it in a cylindrical shape. Then wait for two to three days until the chalk dries. Procedures Phase IV
