1. CHEMISRY ART INTEGRATION PROJECT (SIKKIM) PREPARED BY : SOURAV SINGH CLASS : 11-B KENDRIYA VIDYALAYA NO-1 , DELHI CANTT

2. IMPORTANCE OF CHEMISTRY IN OUR WORLD   Chemistry is important because everything you do is chemistry! Even your body is made of chemicals.    Chemical reactions  occur when you breathe, eat, or  just sit there reading. All matter is made of chemicals,  so the importance of chemistry is that it's the study of   everything.

3. MINERALS Minerals  are solid substances that are present in nature and can be made of one element or more elements combined together 2) Minerals are usually solid , inorganic , have a  crystal  structure , and form naturally by geological processes 3) A mineral can be made of single  chemical element  or more usually a  compound . There are over  4,000 types of known minerals.Two common minerals are  quartz  and  feldspar . Mineral h as a definite  chemical  make-up The  study of minerals is called  mineralogy

4. ALONG WITH THE BEAUTIFUL VIEW OF SIKKIM , THERE IS ALSO THE AVAILABILITY OF SONE MINERALS . THE MINERALS ARE AS FOLLOWS : 1) COPPER 2) ZINC 3) LEAD 4) TALC 5) GRAPHITE
