Curiosity is not about passive receiving of knowledge. Being curious involves action, a desire to know, discover or learn. Children's curiosity should be a central part of their science education. Often in science, curiosity can stem from an everyday occurrence that encourages an observation and promotes a 'what if?' or 'why?' reaction. The questions may not have immediate solutions but the desire to know more can lead to many opportunities for scientific investigation initiated by children's interest. This article describes how an activity with teabags, created initially to encourage good observation skills, ended up promoting curiosity in primary-aged children.
