Title: GLOBAL CLIMATE CHANGE (Global Warming): Examining the Relationship Between the Temperature and Concentration of Carbon Dioxide Grade Level and Course: 6th Earth Science, 9 -12 Earth Sciences, Life Sciences Materials, per student: Global warming article Data Tables (NOAA CO2 Maona Kea data and global temperature changes) Graphing paper (metric if possible) Graphing tools (ruler, colored pencils (2)) Paper For the Class: Butcher paper Markers Instructional Resources Used: (concept maps, websites, think-pair-share, video clips, random selection of students etc.) KWL or Thinking Map (Circle Map), group, random, and class share, video clips, Elmo, projector, computer, Internet access, Google Earth. **Please be more explicit here; for example if you want the teacher to utilize think-pairshare, then state something like “Teacher asks students “Suppose a chemical reaction that is necessary for a cell’s survival is occurring too slowly. How might an organism deal with this dilemma? Students think about the question for one minute, then turn to a shoulder partner and discuss their thoughts to the question. When all students have discussed the question, the teacher leads students in a brief, whole class share out of ideas, scripting possible solutions on the board.” **Please do not just give a list of strategies. California State Standards: this is way, way too many standards. Drill down to which ones specifically your lab addresses the most. Grade 6 Earth Sciences Heat (Thermal Energy) (Physical Sciences) 3. Heat moves in a predictable flow from warmer objects to cooler objects until all the objects are at the same temperature. As a basis for understanding this concept: d. Students know heat energy is also transferred between objects by radiation (radiation can travel through space). Energy in the Earth System 4. Many phenomena on Earth’s surface are affected by the transfer of energy through radiation and convection currents. As a basis for understanding this concept: a. Students know the sun is the major source of energy for phenomena on Earth’s surface; it powers winds, ocean currents, and the water cycle. b. Students know solar energy reaches Earth through radiation, mostly in the form of visible light. d. Students know convection currents distribute heat in the atmosphere and oceans. e. Students know differences in pressure, heat, air movement, and humidity result in changes of weather. Ecology (Life Sciences) 5. Organisms in ecosystems exchange energy and nutrients among themselves and with the environment. As a basis for understanding this concept: a. Students know energy entering ecosystems as sunlight is transferred by producers into chemical energy through photosynthesis and then from organism to organism through food webs. b. Students know matter is transferred over time from one organism to others in the food web and between organisms and the physical environment. e. Students know the number and types of organisms an ecosystem can support depends on the resources available and on abiotic factors, such as quantities of light and water, a range of temperatures, and soil composition. Resources 6. Sources of energy and materials differ in amounts, distribution, usefulness, and the time required for their formation. As a basis for understanding this concept: a. Students know the utility of energy sources is determined by factors that are involved in converting these sources to useful forms and the consequences of the conversion process. b. Students know different natural energy and material resources, including air, soil, rocks, minerals, petroleum, fresh water, wildlife, and forests, and know how to classify them as renewable or nonrenewable. Investigation and Experimentation 7. Scientific progress is made by asking meaningful questions and conducting careful investigations. As a basis for understanding this concept and addressing the content in the other three strands, students should develop their own questions and perform investigations. Students will: a. Develop a hypothesis. b. Select and use appropriate tools and technology (including calculators, computers, balances, spring scales, microscopes, and binoculars) to perform tests, collect data, and display data. c. Construct appropriate graphs from data and develop qualitative statements about the relationships between variables. d. Communicate the steps and results from an investigation in written reports and oral presentations. e. Recognize whether evidence is consistent with a proposed explanation. g. Interpret events by sequence and time from natural phenomena (e.g., the relative ages of rocks and intrusions). Grades 9-12 Life Sciences Ecology 6. Stability in an ecosystem is a balance between competing effects. As a basis for understanding this concept: a. Students know biodiversity is the sum total of different kinds of organisms and is affected by alterations of habitats. b. Students know how to analyze changes in an ecosystem resulting from changes in climate, human activity, introduction of nonnative species, or changes in population size. d. Students know how water, carbon, and nitrogen cycle between abiotic resources and organic matter in the ecosystem and how oxygen cycles through photosynthesis and respiration. Grades 9-12 Earth Sciences Energy in the Earth System 4. Energy enters the Earth system primarily as solar radiation and eventually escapes as heat. As a basis for understanding this concept: b. Students know the fate of incoming solar radiation in terms of reflection, absorption, and photosynthesis. c. Students know the different atmospheric gases that absorb the Earth’s thermal radiation and the mechanism and significance of the greenhouse effect. 6. Climate is the long-term average of a region’s weather and depends on many factors. As a basis for understanding this concept: a. Students know weather (in the short run) and climate (in the long run) involve the transfer of energy into and out of the atmosphere. c. Students know how Earth’s climate has changed over time, corresponding to changes in Earth’s geography, atmospheric composition, and other factors, such as solar radiation and plate movement. Biogeochemical Cycles 7. Each element on Earth moves among reservoirs, which exist in the solid earth, in oceans, in the atmosphere, and within and among organisms as part of biogeochemical cycles. As a basis for understanding this concept: a. Students know the carbon cycle of photosynthesis and respiration and the nitrogen cycle. b. Students know the global carbon cycle: the different physical and chemical forms of carbon in the atmosphere, oceans, biomass, fossil fuels, and the movement of carbon among these reservoirs. Structure and Composition of the Atmosphere 8. Life has changed Earth’s atmosphere, and changes in the atmosphere affect conditions for life. As a basis for understanding this concept: a. Students know the thermal structure and chemical composition of the atmosphere. b. Students know how the composition of Earth’s atmosphere has evolved over geologic time and know the effect of outgassing, the variations of carbon dioxide concentration, and the origin of atmospheric oxygen. Investigation and Experimentation 1. Scientific progress is made by asking meaningful questions and conducting careful investigations. As a basis for understanding this concept and addressing the content in the other four strands, students should develop their own questions and perform investigations. Students will: a. Select and use appropriate tools and technology (such as computer-linked probes, spreadsheets, and graphing calculators) to perform tests, collect data, analyze relationships, and display data. b. Identify and communicate sources of unavoidable experimental error. c. Identify possible reasons for inconsistent results, such as sources of error or uncontrolled conditions. d. Formulate explanations by using logic and evidence. m. Investigate a science-based societal issue by researching the literature, analyzing data, and communicating the findings. Examples of issues include irradiation of food, cloning of animals by somatic cell nuclear transfer, choice of energy sources, and land and water use decisions in California. Common Core State Standards: N/A Lesson Objective: Students will be able to use temperature measurements and ice core observations to provide supporting evidence for global climate change (global warming). Students shall be able to answer the following question: Do temperature measurements and ice core observations provide supporting evidence for Global Climate Change (Global Warning). Differentiation Strategies to meet the needs of diverse learners: English Learners: ELL students will have been given previously a vocabulary activity to help them understand the material being read (what is this activity? Again, specifics needed). Their assessment at the end of the unit will be modified (see EVALUATE). Special Education: Same as for ELL plus the students will be incorporated in groups that can help them. Restate this into something like “Students will be strategically placed into mixed ability groupings to facilitate the use of peer tutors during the investigation. Additionally, students will have been previously instructed in the major terms of the unit through the use of picture cards”…. GATE: Students will analyze the data on the tables provided, and hypothesize what variables might be changed so as to impact the outcome of the analysis. ENGAGE Describe how the teacher will capture the students’ interest. What kind of questions should the students ask themselves after the engagement? We need something really engaging here…perhaps a short video clip from youtube, or images of melting Alaskan glaciers, etc. Perhaps something like this: http://www.gly.uga.edu/railsback/AG/BerlinerHutte.html 1) After viewing the images, students are asked to share their observations with a partner, and then with the class in a whole group discussion. 2) Students are then asked, “How can we say that the increase in temperature on Earth is due to an increase in CO2 concentration?” 2) Students are asked to prepare and fill the K and W columns of a KWL chart or to create a circle map (“Thinking Map”) about what they know regarding global warming. Students will review this data towards the end of the unit to address misconceptions, etc. This is a good place to start looking at the general perception of global warming and to come back to after the unit of study to support claims or to address misconceptions. This belongs in the beginning of the explore unit…it really is an intro to the lab, more so that an “attention getter” 3) Students are shown the trailer of Al Gore’s film “An Inconvenient Truth) http://www.youtube.com/watch?v=wnjx6KETmi4&feature=related Students are randomly asked to share their reactions to the trailer or teacher answers questions they might have. This is a good engage too… 4) Teacher may place a previously highlighted article about global warming on the document projector and slowly scroll through it, instructing students to record information from it (a reading preview strategy). http://www.aaas.org/news/press_room/climate_change/mtg_200702/aaas_climat e_statement.pdf Again, this is more appropriate in the explore section of the lab. Students are asked individually to write down, on the back side of the sheet of paper previously used, the words or sentences that they think are relevant to the lesson. Students share with their group the information they have collected. This is followed by a class share and the information is written on the board or poster paper by either a student(s) or the teacher. This appears to be a repeat of the KWL strategy…I would stick with it instead. EXPLORE Describe the hands-on laboratory activity that the students will be doing. List the “big idea” conceptual questions that the teacher will ask to focus the student exploration. If students don’t come up with the desired ideas, the teacher should direct them towards the use of recorded data both for temperature and for CO2 concentrations. DO NOT GIVE TOO MUCH DETAIL HERE. SAVE THE DETAIL FOR THE STUDENT SHEET. JUST GIVE ME A SUMMARY OF THE HANDS ON ACTIVITY. EXAMPLE: In groups of four, students will examine reference tables containing data detailing the temperatures and carbon dioxide concentrations found on Mauna Kea between the years 1980 through 2010. Students will graph the relevant data and analyze these graphs to determine if there is a correlation between carbon dioxide concentrations and temperature. Students are told that they will be looking at that data and will examine if there is a correlation and whether it is positive or negative. 7) Divide the students into groups of four. Each group will need a set of reference data tables. Students work in groups but each student is responsible to plot his/her own graphs. -Each student will need graph paper and pencil with which to graph the data from the data tables for carbon dioxide concentration and temperature measurements. (2 separate plots) -Students will determine a scale that is appropriate for the data to be plotted. -The independent variable and dependent variable should be identified and the axes of the graph labeled. Depending on students’ familiarity with plotting, the teacher could help students setup the variables on the plots and help choose the scales. Time frame used: 1980 - 2010 8) Graph the data for CO2 and temperature from Data Tables 1 and 2 using different color pencils for each set of data. Be sure to label the axes of the graph. Students should draw 2 separate graphs. Big Idea Conceptual Questions: Observe the resulting line on the graphs for temperature and carbon dioxide concentration. Are the lines increasing, decreasing, or staying the same? Write your observations under the graphs. What makes scientists say that global warming is actually occurring, and that its increase is related to increased levels of CO2? EXPLAIN What is the “big idea” concept that students should have internalized from doing the exploration? List the higher order questions that the teacher will ask to solicit student explanations for their laboratory outcomes, and justify their explanations. Explain in one sentence or two what the “big idea” concept is that students should take away from this lesson. Higher Order Questions: Why do increased levels of CO2 in the atmosphere contribute to higher global temperatures? What is the unintended effect of these elevated temperatures? As scientists, what would you do to study the warming problem? What type of experiment might you design to help address this problem? Observe the resulting line on the graphs for temperature Are the temperatures increasing, decreasing, or staying the same? Write the observation under the graph. 10) Compare the resulting line on the graphs for carbon dioxide. Are the concentrations increasing, decreasing, or staying the same? Write the observations under the graph. 11) Is there a relationship apparent between the temperature and carbon dioxide concentration? If so, does the graph show a positive correlation, a negative correlation between the two? These are not “big idea questions”. EXTEND Explain how students will develop a more sophisticated understanding of the concept. How is this knowledge applied in our daily lives? 1) Students will work with a partner to discuss the data collected and make a list of recommendations for further study. (for example, the need for more data from different locations and over a longer period of time; the need for deeper analysis of that data) Class discussion of results: Do the data collected and the analysis from your graphs supply sufficient evidence for global warming? Why or why not? Students work with their partners and come up with a list of recommendations they would make to better investigate Global warming. (More data is needed, analysis from different locations is needed, data over a longer period of time is needed, other causes could be in play (volcanic activity in Hawaii)’etc. .) Students are made aware of the fact that data obtain from scientific research needs to be analysed in order to help study and answer specific questions. Having raw data alone is not a goal per se. Students must realize that in everyday life one should not stop at observations but one should interpret those observations. 2) Students watch an 8 minute video produced by the United Nations Foundation and answer a few questions on their worksheet. http://www.youtube.com/user/unfoundation#p/search/0/-MY-i_kdwe0 3) Students may measure CO2 concentration in different parts of the school, both inside and outside, at various times throughout the day, using a CO2 probe or kit that is readily available from various retailers. See below for resources. http://store.pasco.com/pascostore/showdetl.cfm?DID=9&Product_ID=5061 4&Detail=1 http://homeharvest.com/carbondioxidemonitorcontrol.htm EVALUATE How will the student demonstrate their new understanding and/or skill? What is the learning product for the lesson? Students will accurately produce two graphs with proper labels, and will be able to explain the correlation that exists between carbon dioxide concentrations and atmospheric temperature. Prediction: Measurements of temperature and carbon dioxide concentration in the atmosphere sill show a correlation between an increasing amount of CO2 and an increase in atmospheric temperature. (It is important to note that CO2 is one of several greenhouse gases and the term ppm should be explained. Increases in carbon dioxide, methane, nitrous oxide, and reactive trace gases are considered as the effect of increasing human activities) Students will give an example of another observation which could be done using the same technique (comparing growth between boys and girls, checking ocean temperature vs CO2 levels, comparing CO2 concentration within a year, etc.) Why is this a significant final product? I don’t get it. This should be your final evaluation piece to make sure that they really internalized the concept. Background Knowledge for the Teacher: This is where you really need to explain the content in depth. You may take an explanation directly from a webpage, as long as it is recent research, a credible source, and fully cited. It is not unusual for this portion to be one half to one full page. Teacher should be familiar with Global Climate change. Scientist now use this term instead of global warming as some areas on Earth are actually cooling down. Teacher should also be familiar with green house gases and their emissions. Good sites to investigate: http://www.aaas.org/news/press_room/climate_change/ *Attach student pages to this lesson plan. No student pages attached… Note: Draft 1 I am designing the work sheet, reformatting the data table (not included in original lesson plan and which I had to come up with). I am also going to plot the data myself to see if all is ok Marcus 7/1/2011 ok what is this stuff? Teacher background? Embargoed: Not for release until 12:30 p.m. Pacific Standard Time Sunday, 18 February 2007 AAAS Board Statement on Climate Change Approved by the Board of Directors American Association for the Advancement of Science 9 December 2006 The scientific evidence is clear: global cli-mate change caused by human activities is occurring now, and it is a growing threat to society. Accumulating data from across the globe reveal a wide array of effects: rapidly melting glaciers, destabi-lization of major ice sheets, increases in extreme weather, rising sea level, shifts in species ranges, and more. The pace of change and the evidence of harm have increased markedly over the last five years. The time to control greenhouse gas emissions is now. The atmospheric concentration of carbon dioxide, a critical greenhouse gas, is higher than it has been for at least 650,000 years. The average tem-perature of the Earth is heading for levels not experienced for millions of years. Scientific predictions of the impacts of increasing atmospheric con-centrations of greenhouse gases from fossil fuels and deforestation match observed changes. As expected, intensi-fication of droughts, heat waves, floods, wildfires, and severe storms is occurring, with a mounting toll on vulnerable ecosystems and societies. These events are early warning signs of even more devastating damage to come, some of which will be irreversible. Delaying action to address climate change will increase the environmental and societal consequences as well as the costs. The longer we wait to tackle climate change, the harder and more expensive the task will be. History provides many examples of society confronting grave threats by mobilizing knowledge and promoting innovation. We need an aggressive research, development and deployment effort to transform the existing and future energy systems of the world away from technologies that emit greenhouse gases. Developing clean energy tech¬nologies will provide economic opportu¬nities and ensure future energy supplies. In addition to rapidly reducing green-house gas emissions, it is essential that we develop strategies to adapt to ongoing changes and make communi-ties more resilient to future changes. The growing torrent of information pres-ents a clear message: we are already experiencing global climate change. It is time to muster the political will for concerted action. Stronger leadership at all levels is needed. The time is now. We must rise to the challenge. We owe this to future generations. The conclusions in this statement reflect the scientific consensus represented by, for example, the Intergovernmental Panel on Climate Change (www.ipcc.ch/), and the Joint National Academies’ statement (http://nationalacademies. org/onpi/06072005.pdf).
