WEBQUEST

Global Warming - Teacher's Section

The Global Warming Webquest is modeled on recommendations made in the National Science Education Standards (National Research Council, 1996) and meets the following Inquiry and Science Content standards:

For Middle School Students

Content Standard A – Understanding about Scientific Inquiry
“Think critically and logically to make the relationships between evidence and explanations.”

Students work with peers and consider the evidence that informs decisions related to climate change to draw links between evidence and explanations.

Content Standard B – Physical Science
“Students should develop an understanding of properties of matter, motion and forces and transfer of energy.”

Students learn the transfer of energy through models illustrating the “greenhouse effect.” Students are given an opportunity to better understand factors that contribute to changes in the Earth’s climate, including the Earth’s orbit variation in solar emission and ocean circulation, and changes in greenhouse gases and aerosol concentrations in the atmosphere.

Content Standard C – Life Science
“Students should develop an understading of regulation and behavior and populations and ecosystems.”

Students develop a deeper understanding of populations and ecosystems as they learn about possible impacts of global climate change and changing ecosystems. Adaptations among organisms and populations are likely as temperature and water availability fluctuates.

Content Standard D – Earth and Space Science
“Students should develop an understanding of the Earth in the solar system.”

Through data and information presented on global atmospheric patterns and the role of oceans in climate , students develop a better understanding of the structure of Earth as a system, Earth’s geographic history, and Earth’s role in the solar system. Students also learn that solar energy is the Earth’s main source of energy and that climate patterns, seasons, and ecosystems depend on the input, transformation, and retention of solar energy.

Content Standard E – Science and Technology
“Students should develop understandings about science and technology.”

Students will observe the many ways in which scientists have collected data and predicted future climate change. Methods of data collection and analysis are explained. Data from the last century are used in computer models to understand patterns over time.

Content Standard F - Science in Personal and Social Perspectives
“Students should develop understanding of natural hazards and risks and benefits.”

Students gain a better understanding of natural hazards as they relate to global climate patterns. As students examine potential impacts of climate changes, they are challenged to think about estimating rates of change, types of natural disasters and possible locations of those disasters.

Content Standard G – History and Nature of Science
“Students should develop an understanding of science as a human endeavor and nature of science.”

The webquest activity examines the impact of human endeavors on the climate system and how that information can be used to predict future events.

For High School Students

Content Standard A – Understanding about Scientific Inquiry
“Students should develop understandings about scientific inquiry, recognize and analyze alternative explanations and models and communicate and defend a scientific argument.”

Through the “use of empirical standards, logical argument and skepticism” students analyze the data presented, evaluate how they were generated, and consider their validity and significance of in predicting potential global climate change. Students use evidence to support and defend their positions, and think logically and critically about potential future consequences of global climate change.

Content Standard B – Physical Science
“Students should develop understandings of chemical reactions, conservation of energy and the increase in disorder, and interactions, of energy and matter.”

Students explore the role of greenhouse gases in natural and amplified warming. Students also explore evidence of human impacts and changing CO2 levels and are required to apply their knowledge of dynamic systems, data analysis, and the interactions of matter and energy. Students look at methods of collecting and interpreting evidence. Students use computer models to apply knowledge of chemical interactions and their consequences to forecast a changing but uncertain climatic future.

Content Standard C – The Cell
“Students should develop understanding of the intersependence of organisms, and matter, energy and organization in living systems.”

Students explore how the carbon cycle, cellular functions, chemical reactions, and human population size and activities affect the environment. Data from prehistoric climates allow students to apply their understanding of matter, energy, and organization in past living systems to think critically about the impacts of human behavior. Students use models to predict the effects of future climate change on health and disease, agriculture, changing water resources, and loss of biodiversity.

Content Standard D – Earth and Space Science
“Students should develop understanding of energy in the Earth system.”

The webquest activities give students a chance to work with scientific evidence to examine the effects of the Earth’s energy balance on climate. Students investigate evidence for global warming through deep time, collect data on past changes, and compare those data with more recent data and with changes in human population sizes and activities.

Content Standard E – Science and Technology
“Students should develop understandings of understandings about science and technology.”

The webquest activities provide opportunities for students to gather and analyze data developed by advanced technology and modeling systems. Students see how the amounts and forms of data increase as new technologies are developed and employed.

Content Standard F – Science in Personal and Social Perspectives
“Students should develop understandings of environmental quality, natural and human induced hazards, and science and technology in local, national and global challenges.”

The webquest activities allow students to work in collaborative teams to collect data, think about their implications, and consider potential future global challenges. After students understand the science, they have opportunities to discuss implications for public policy and economics.

Content Standard G – History and the Nature of Science
“Students should develop understandings of science as a human endeavor and the nature of scientific knowledge.”

Students learn that scientists share their methods and data, review each other’s work, and come to differing conclusions about results. Working as scientists, students discuss the data provided, share their interpretations, pose additional questions, and debate the significance of climate uncertainties in the future.
