Science is classified into three groups biology,Chemistry and Physics,but there is difference between them like the biology talks about the living things or the living organisms like:plants, humans and animals. Chemistry talk about the chemicals things or chemicals materials like:Perfumes or slime .Physics is so hard ,because it is talking about physical things or materials. Children think that Science is so simple or easy ,because they take Plants,animals,humans,light,electricity,living things and non living things,vertebrate animals and invertebrate animals.But,when they become bigger they will say the opposite of this,because Science is so heavy.
