ABSTRACT
Science is certainly about investigating, but if the essence of being scientific were really no more than carrying out technological tests on absorbent paper or slippery slopes, would we ourselves ever have become enthusiastic science students, let alone science teachers? A scientific investigation is so much more. It is an enterprise which searches for explanations about why phenomena happen in the way they do, using previous knowledge, new observations, imaginative analogies, and carefully designed experiments. As Einstein once said, scientists are people ‘with a passion to explain’. That is the appeal of science.
