Science is found everywhere you look. Sometimes you can find it where you least expect it to be.  
Science  plays a constant important role in my daily life.
Science for me hasn't always been my strong subject in school and I very easily tend to get intimidated. But when I look at my daily life and realize how much science plays a role in it. Science isn't bad at all, it has allowed me to do many things every day. From the way the microwave heats up the water for my coffee every morning or the way my body digests the food I eat every meal and makes it into energy or even a trip to the doctor’s office with my son, science is a constant companion and without it, my life would have turned out very different indeed.
Science has changed and impacted the way I live in many ways. It has educated me about life, about marvels that exist in this world, and about the relationship between these wonders. Science has taught us all to expand our knowledge and covers everything from a very little thing like molecules to planets and the whole universe. 
Scientists are learning to predict earthquakes, to study many other natural events such as storms. Scientists are also studying various aspects of human biology and the origin and development of the human race. The study of the natural world may help improve life for many people all over the world.
Basic knowledge of science is essential for everyone. It helps people to find their way in the changing world.
