ABSTRACT

The study on the production of chalk out of seashells were designed to produce quality dustless and long lasting chalk to compare with the standard existing commercialized chalks if there are any, which was sold in the market. The chalk out of seashells is for local or non-local used for schools or any educational aspects or even at home which can be form into different sizes and according to your will. I used the seashells to recycle and transformed it into a useful product that will be used in our developing community. The production is based on the following procedures.

Shells washed up onto a beach empty and clean, the animal having already died, and the soft parts having rotted away or having eaten by either predators or scavengers. Empty seashells found by beachcombers, and collecting these shells is harmless hobby or study. However, the majority of seashells, which offered for sale commercially, have been collected alive (often in bulk) and then killed and cleaned, specifically for the commercial trade. This type of exploitation can sometimes have a strong negative impact on the distribution of rarer species, and on local ecosystems. Many kinds of sea animals have exoskeletons or shells that may, after death, wash up on the beach. And may be picked up by beachcombers; these include remains from species in other invertebrate phyla, such as the molted shells or exuviates of crabs and lobsters, the shells of barnacles, horseshoe crab shells, sea urchin and sand dollar tests, brachiopod shells, and the shells of marine annelid worms in the family Serpulidae, which create calcareous tubes. B. THEORETICAL FRAMEWORK

Some people considered seashell as useless in terms of reasonable things. Because of my research, this belief will change to a bright side. I will prove that seashells are not useless but are significant ones.

C. HYPOTHESES
1.) There is significant difference between chalk from seashells and the leading commercial one.
