I. Introduction

Natural resources are materials that are available in the natural environment, and they are sometimes referred to as primary resources. Examples of natural resources includewater, air, plants, animals, etc. Natural resources may or may not be renewable, which means there is always a possibility that the universe will run out of certain kinds of natural resource at somepoint.
Classification of Natural Resources Based on Renewability: Renewable Resources, Resource, which can be replenished or reproduced easily Examples: sunlight, air, wind (continuously available and notaffected by human consumption) Non-renewable Resources, Resources, formed over very long geological periods. These cannot be replenished once they get depleted. Only metallic minerals can be re-used byrecycling. Others cannot be recycled. Examples: Minerals, fossils, coals and petroleum.
Every natural resources like air, water sunlight, land mineral, energy, oxygen ,food has and effect to allhuman being we need them to survive in the daily basis.
The purpose of this experiment is to see the natural resource in a changing environment and that’s why I use salt and water and my hypothesis isthat expect to see a crystal form in the towel that I use and that crystal is call stalactite (a column of salt.)
