Science scientific process

Scientific and Technological Literacy. There is increasing concern within the business community about the effectiveness of the precoUege education system (K—12) in preparing students for an increasingly technically sophisticated workplace. This issue is of special importance to the chemical enterprise, which will find it more difficult to operate effectively in a society that does not understand science and the scientific process (42). 

This chapter illustrates that the potential of scC02 for reaction engineering of homogeneous catalysis offers a great scope for possible scientific and technical innovation. This newly emerging field of catalysis research lies at the interface of molecular sciences and process engineering and its future development will require truly interdisciplinary efforts from experts in both fields. 

There are many university science professors who only rarely perform experiments. Instead, they oversee undergraduate, graduate, and postdoctoral students who perform the actual experiments. The professor, however, is still very much engaged in the many other aspects of the scientific process and is by all measures a professional scientist. 

Risk appraisal thus includes the scientific assessment of the risks to human health and the environment and an assessment of related concerns as well as social and economic implications (Renn and Walker 2007). The appraisal process should be clearly dominated by scientific analyses - but, in contrast to traditional risk regulation models, the scientific process includes both the natural/technical as well as the social sciences, including economics. The risk appraisal comprises two stages ... 

Precaution and Environmental Science. When the precautionary principle is discussed in its relationship to science, it is often portrayed as an antiscience or a risk-management principle that is only used after undergoing conventional scientific processes. As discussed earlier, in practice the limitations of science to characterize complex risks show that precaution is not at odds (Kriebel et al., 2001). Further, precaution is not just about additional safety factors or changing risk assessment default assumptions. Research by U.S. EPA scientists has demonstrated that many of the EPA s Reference Doses - or conservative safe exposures - may correspond to risks of greater than 1 in 1000, meaning that safety factors alone may not protect health (Castorina and Woodruff, 2003). 

The corresponding laboratory manual for The Sciences uses common lab equipment to give students first-hand experience with the scientific process (5). The labs most relevant to the topics taught in Science and the Concept of Evolution are related to prediction and measurement in science, scientific models and modeling, the acceleration due to gravity, the Laws of Thermodynamics, electromagnetic wavelengths and spectra, stellar evolution, heredity and probability, and natural selection. 

Scientific models are based on physical observations that establish some facts about the system or object of interest. Scientists then combine these facts with appropriate laws or scientific principles and assumptions to produce a picture that mimics the behavior of the system or object to the greatest possible extent. It is on the basis of such models that science makes many of its most important advances, because such models provide a vehicle for making predictions about the behavior of a system or object. The predictions can then be tested as new measurements, technology or theories are applied to the subject. The new information may result in modification and refinement of the model, although certain issues may remain unresolved by the model for years. The goal, however is to continue to develop the model in such a way as to move it every closer to a true description of the natural phenomenon. In this way, models are vital to the scientific process. 

It is essential, therefore, that young people understand something of the nature of scientific processes and of the nature of scientific models and theories, and how they relate to evidence. Of all the science subjects, chemistry offers exceptional opportunities to appreciate the relationships between evidence based on observation of the natural world, model-building as a means of making sense of...

Up to this point we have focused on the spectrometer and the underlying data quality. However from an analytical science perspective, process is important as illustrated in Figure 1. Scientific knowledge is founded upon relevant and robust information generated from reliable data.
