Let's unpack what they mean: Wonder is basically the process of forming a question. Oftentimes, questions arise from conflict or a need. For instance, at the beginning of World War 1, officials wondered how to save electricity, which was expensive. Following the WISE process to address the issue resulted in the creation of daylight saving time. Investigate is the process of gathering all information possible about the challenges recognized by wondering. This means you must gain all the information about problems or issues you need, and it is important to gather information from all viewpoints. This means collecting information in any way possible and can require a lot of time and effort. When investigating conditions of the Women's Lunatic Asylum on Blackwell's Island, for example, journalist Nellie Bly decided to feign insanity to become a patient herself to gather information about the conditions in the asylum. Speculate is where you take all of the information you have gathered and think of multiple possible solutions to a problem. One example was the problem of how to get information from one side of the country to another. This led to the creation of the Pony Express. However, another solution was the Western Union transcontinental telegraph line, which proved to be the better solution. The Pony Express closed two days after the telegraph line was completed. Evaluate is where you consider all possible solutions to determine the one that is most plausible or realistic. The "best" solution could be determined by the criteria that are most important for the problem. Examples of these criteria include legality, cost, longevity, and morality. Professor of animal science Temple Grandin, for instance, had to take these particular criteria into consideration when looking at the humane treatment of cows for slaughter. After evaluating multiple solutions to the problem of how to efficiently and morally slaughter the cattle, she created curved loading chutes and center-track restrainer systems. These inventions are widely used in slaughterhouses today.
