When a teacher tries to teach something to the entire class at the same time, chances are, one-third of the kids already know it; one-third will get it; and the remaining third won’t. So two-thirds of the children are wasting their time.

When children are truly involved in the scientific process they gain understanding, knowledge, and life skills. They deepen their awareness of what's going on around them and how others contribute to their well-being.

All children, are born with the disposition to make sense of their experiences.

Science is a particular way of thinking about things.

Learning to deal with setbacks, and maintaining the persistence and optimism necessary for childhood's long road to mastery are the real foundations of lasting self-esteem.

Young children are unlikely to have their self-esteem strengthened from excessive praise or flattery. On the contrary, it may raise some doubts in children; many children can see through flattery and may even dismiss an adult who heaps on praise as a poor source of support-one who is not very believable.

Of course children benefit from positive feedback. But praise and rewards are not the only methods of reinforcement. More emphasisshould be place on appreciation--reinforcement related explicitly and directly to the content of the child's interest and efforts.
