A clear, colorless liquid is poured into a funnel at the top of a box, and comes out into a container at the bottom. What happened in the box? The process is repeated, only this time the liquid comes out colored. What's going on? A third repetition gives still another different color! And a fourth trial results in no liquid coming out the bottom at all! What will a fifth trial do? Or a sixth? The challenge to a person observing this behavior is to figure out what's going on in the box, without seeing the inside. This is exactly the sort of problem faced by scientists investigating the nature of the atom, since it is impossible to "open up' the atom and take a look inside. Instead, the process involves a series of observations, hypotheses, predictions, tests, and conclusions, all of which may have to undergo revision as new behavior is observed.
