What is Natural Science?Natural science is one o( three di)isions o(science! the other t*o being the social

sciences + psychology! sociology!economics! etc. and the formal sciences +mathematics! logic! and statistics.The natural sciences are astronomy! biology!chemistry! earth science! and physics. Thesesciences are the basis (or applied sciences.

What is Applied Science?

Applied science is the application o(scienti(ic -no*ledge trans(erred into a

physical en)ironment.Fields o( engineering are closely related toapplied sciences. t is also important(or technology and industrial de)elopment.

physics is connected mainly *ith matterin relation to energy.

Biological sciences deal with living things ,while the physical sciences are connected withthe properties and behavior of non-livingmatter .

CHEMISTRYCHEMISTRY

0Cooking is chemistry.0Everything you can touch or taste orsmell is a chemical.

0It's the explanation for everyday things,like why laundry detergent works betterin hot water or how baking soda works or

why not all pain relievers work equallywell on a headache.



Chemistry the central science

If you know some chemistry, you can makeeducated choices about everyday products thatyou use.

It draws on chemistry and physics for its

foundation and applies these basic physicallaws to living things.

BIOLOGYBIOLOGY!he science of biology is, broadly speaking, the

study of living things and how they interactwith all of the things around them.

Why study natural science?

The study o( natural science is to buildstudents9 understanding o( (undamentalconcepts o( mainly physics! chemistry andbiological sciences in a simple *ay *hich *illma-e them (amiliar o( the (acts in relation tothese areas.

As a result! students *ill (ind interest to *or-

com(ortably in a scienti(ic en)ironment and*ill try to understand the relationship amongdi((erent disciplines.
