How to conserve natural resources 
All aspects of the environment have a deep impact on our lives. Science helps to
learn about how the earth functions, and how to make use of natural resources. It also
teaches us how the lack of these resources affects living things, and how one can conserve
these resources.
Science helps you us to learn about the various weather conditions, and helps us to
distinguish between normal weather and dangerous weather. With this knowledge, you can
stay alert about natural disasters or survive the disaster.
The processes and ideas of science are of great importance  to  everybody  in  three
ways. The first is in their personal lives,  for  example  so  that  they  can  validly identify the
components of a  healthy life- style. The second is in their civic lives, so that they take an
informed  part in  social decisions,  for  example  on  future options  for electricity supply.
The third is in their economic lives, where they need to be able  to  respond  positively  to
changes  in  the  science-related  aspects  of  their  employment.
Science is everywhere. Science develops critical thinking. It motivates to ask critical
questions and helps to proceed with analytical thinking and results in solving our problems.
Every decision we make is based on these processes. We ask questions out of curiosity
(what is the problem?), we construct hypothesis (may be this is the cause), we test the
hypothesis (how to confirm the inferred cause?)  test it with evidence and evaluate the
result (Did the solution work?), and make future decisions based on that result. This is the
product of science.
