I can explain how science can inform public policy. I can identify a problem or need, propose a design and choose the best solution for the problem. I can explain why a design should be regularly looked at and why the ideas of the design should be tests, changed and refined. Given a scientific situation, I can tell the difference between observations and inferences. When planning and conducting investigations, I can research and use the appropriate safety precautions. (e.g., OSHA, Material Safety Data Sheets(MSDS), eyewash, goggles, ventilation) I can make, interpret and apply physical and conceptual models that represent or explain systems, objects, events or concepts. Based on the data, I can decide what degree of precision is necessary. I can round off calculator operations to the proper number of significant figures. I can develop oral and written presentations using clear language, accurate data, appropriate graphs, tables, maps and available technology. I can draw logical conclusions based on scientific knowledge and evidence from investigations. I can give examples of how scientific investigations require input from men and women from many disciplines in and out of science. I can explain how the methods and procedures used to gather evidence must be clearly reported to allow other investigations to be done in the future. I can explain how reliable scientific evidence improves scientists’ ability to make accurate predictions. I can explain how ethical practices in science are necessary to reduce bias. I can justify that scientific theories are explanations of large bodies of information and/or observations that hold up to repeated testing. I can explain how inquiry helps to produce data needed for all scientific fields.
