Different plots were treated in different ways with nutrients that are known to affect plant growth. 1. Some plots, called controls, received no treatment. 2. Some plots were given a group of essential nutrients, such as phosphorus and potas- sium, but no nitrogen. 3. Some plots were given the same set of nutrients but different amounts of nitrogen. Think for a moment about this experimental design. All of the plots start with the same soil and receive the same rainfall. The only difference between them is the amount of nitrogen and other nutrients.
After scientists have established a regularity in nature, they can go on to ask an important question: What must the world be like in order for this regularity to exist? They will, in other words, construct a theory, a mental (and usually mathematical) picture of how the world operates. In the next chapter, for example, we will see how the English scientist Isaac Newton formulated a theory about why things fall, a far-reaching theory embodied in what we now call the law of universal gravitation.
Nevertheless, a few basic steps taken together can be said to comprise the scientific method. OBSERVATION Figure 1-2 • Plato argued that humans observing nature were like men watching shadows on the wall of a cave. indd 4 If our goal is to learn about the world, then the first thing we have to do is look around us and see what’s there. This statement may seem obvious to us in our modern technological age, yet throughout much of history, learned men and women rejected the idea that someone can understand the world simply by observing it.
