The core logic of science is that you can test ideas or answer questions, by systematically gathering evidence (or data), and then considering how that evidence supports or refutes your idea.<\/strong><\/p>\n

Of course, there are lots of intermediary steps in the process, including doing initial research into the question, so that we understand what is already known about the study system, the biological process, or the organism that is the focus of our question.\u00a0 We then form a testable hypothesis, stating what think will happen.\u00a0 Next comes the test of the hypothesis, through careful and controlled observation or experimentation.\u00a0 Data is gathered and analyzed, specifically to see whether or not the outcome of your experiment either lends support or helps refute your hypothesis.\u00a0 These steps in the scientific method are often portrayed as linear an uni-directional.<\/p>\n

\n \"\"<\/a>\n
Sometimes, science is portrayed as a linear process.<\/figcaption>\n <\/figure>\n

In reality, the scientific process is an iterative, rather than a linear process.\u00a0 The scientific process a continuous and ongoing cycle between theory and data.\u00a0 Here, the word \u2018theory\u2019 is used to represent an explanation, or a logical framework, that represents our current understanding of the way that things work.\u00a0 Theory is used to classify, interpret and predict the world around us.<\/p>\n

\n \"\"<\/a>\n
In fact, it is much more accurate to portray science as a cyclical or iterative process, where questions are constantly re-examined and refined, in the context of new evidence or data.<\/figcaption>\n <\/figure>\n

For example, one common theory in ecology is that:\u00a0 as the size of your yard or garden increases, so too will the number of species that inhabit your garden.\u00a0 This is known as the \u2018species area relationship\u2019.<\/p>\n

\n \"\"<\/a>\n
For quite some time, scientists believed that the number of species would increase, as a direct function of the size of habitat available to those species.<\/figcaption>\n <\/figure>\n

But, even after theories have been formed, scientists continue to ask question, gather additional data, and consider how what they knew . . . Or thought they knew . . . Aligns with any new information or data they may gather.\u00a0 Good scientists must know and consider previous observations, and synthesize this existing data with new observations . . . All in an effort to refine and improve theory.<\/p>\n

If we go back to our species area relationship, you\u2019ll notice that the graph is linear.\u00a0 For a long time, this is how scientists thought biodiversity worked: as habitat size increased, the number of species in that habitat increased.\u00a0 But, after gathering more data, scientists realized that the relationship is more of a curvi-linear relationship.<\/p>\n

Increasing the size of a habitat, or having a larger garden, increases the number of species you will find . . . But only up to a point.\u00a0 At some point, you\u2019re going to hit the limits of the species pool in your vicinity, such that increasing garden size results in fewer and fewer new species in your garden.\u00a0 The number of species eventually levels off, rather than continues to increase.<\/p>\n

\n \"\"<\/a>\n
We now know, due to systematic observation and experimentation, that the number of species does increase as habitat size increases, but only up to a point. Eventually, the number of new species in an area will level off, even as the size of habitat increases.<\/figcaption>\n <\/figure>\n

This is one of the most beautiful things about science ~ it allows for, and even encourages repeated and critical analysis of ideas.\u00a0 Critical analysis is especially common for new ideas . . . But even established ideas ~ explanations that have long gained acceptance ~ are subject to critical analysis, review and revision, as new data becomes available.<\/p>\n

How does this apply to your garden?<\/h3>\n

Consider how the process of inquiry is, in your own garden. Have you ever made an observation that brought many questions to mind? Perhaps you saw a caterpillar that you could not identify, and you wanted to know more: what is the species?; is it new to this area?; what are its host plants? Once you found the answers to your original questions, did it bring more questions to mind? Congratulations! You’re thinking like a scientist!<\/p>\n

If you’ve ever had this type of circular experience of inquiry ~ where an observation led to questions, and the answers to these questions led to more questions ~ consider sharing your experience in the comments.<\/p>\n
