Very Small and Far Away: Measuring and Observing Extremes • Read chapters 8 and 14. Don’t forget to check out the key terms in the glossary. • Discussion -2 Questions: • What do you measure, how do you measure it (what tool or device do you use, and what are the measurement units)? How is this measurement important or necessary within your daily life? • What would the consequences be if your measurements were inconsistent or incorrect? In science and in your daily life, what are the advantages of precise and accurate measurement? • Are there ways in which technology could help you to perform this measurement differently and perhaps with more accuracy or precision? • Do other people use the same system of measurement as you? If not, how else do they make this measurement? • Project- Community Health Department Investigation • Use the data provided for your investigation • Typo: Be sure to use the "Save As" Shawn_Edwards_Assignment2.ppt or .pptx NOT .doc • Evidence supporting hypothesis • Questions to further pursue to test this hypothesis: • "Measure what can be measured, and make measurable what cannot be measured." • — Galileo Galilei • Seminar this week will evaluate the various forms of direct and indirect evidence for, and measurements made that relate to the global phenomenon of climate change. • Anthropogenic, or human-caused climate change is a topic frequently discussed within all fields of science as well as by the media and general public. However, those not part of the scientific investigations are likely not aware of the various forms of evidence, both direct and indirect that have identified climate change and its likely causes. This is due in part to the unique forms of measurement and monitoring that are not familiar to many, as well as misunderstandings of how scientific data cannot only be collected for current conditions but also those dating back thousands, and even millions of years. We will discuss the various forms of data used to support the theory of climate change, and how this data is collected. We’ll also discuss the gaps in the evidence and how those gaps are or could be addressed in the future. • What is a global warming? • Helpful sites: • Frequently Asked Questions about Global Warming: • http://www.ncdc.noaa.gov/oa/climate/globalwarming.html • The Greenland Ice Sheet: A Record of Climate Change: • http://www.teachersdomain.org/asset/ess05_int_greenland/ • Clues from Past Climates: • http://www.teachersdomain.org/assets/thinktv/ttv10/ttv10_int_clues/ind ex.html • According to NOAA, he term Global Warming refers, without any implications for the cause or magnitude, to the observation that the atmosphere near the Earth's surface is warming. • Why should we care about global warming? • What is the Greenhouse effect? • How is the greenhouse effect related to global warming? • Taken from: http://www.ncdc.noaa.gov/paleo/globalwarming/what.html • What types of measurements indicate that climate change is occurring? • How were these measurements collected? • What are some of the challenges associated with collecting data over large periods of time (i.e., 100s of years)? • How has technology enhanced our ability to collect the data necessary to understand climate change? • http://www.ncdc.noaa.gov/cmb-faq/globalwarming.html#q8 • What additional data would be useful? • What are the risks associated with waiting for more data as well as reacting to incomplete data? • What other questions within science (perhaps environmental or even medical) are not fully answered but demand attention and reaction? • Go to science center tour through the link below: • http://khe2.adobeconnect.com/kusc_tour/ • Sign in as Guest and type in your name.
