– e.g., hazardous chemicals in water
– e.g., increased ‘Global Warming’ gases
– e.g., pesticides with negative side effects
• Habitat Damage

How School Science addresses social & environmental
problems?
The STS-E Principle
Defining Scientific
Literacy
“The scientifically literate person is one who is
aware that science, mathematics, and technology are interdependent human enterprises with strengths and limitations;
understands the key concepts and principles of science;
is familiar with the natural world and recognizes both its diversity and unity;
and uses scientific knowledge and scientific ways of thinking for individual and social purposes.”
Project 2061
Literacy Goals for School Science
• Learning ‘Science & Technology’
• Learning ‘To Do’ Science & Technology’
• Learning ‘About’ Science & Technology
• Learning to/taking Socio-political Action
Introducing the Problem…
• Many scientists believe that human activities such as burning fossil fuels to drive cars and generate electricity are causing the Earth’s atmosphere to warm. This “global warming” gradually changes the climate of the planet. Which are, according to your opinion, the best ways to respond to this situation?
WHAT THE IPCCSCIENTISTS SAY
The mean temperature of the Earth is increasing and the use of fossil fuels is at an all time high.
WHAT THE SCIENTISTS SAY:From the Climate Change Statement of the AAAS Board, released 2-18-07
• The scientific evidence is clear: global climate 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, destabilization 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.
Ice melting and and sea-level rise
International intergovernmental Bodies
• UNFCCC Executive Secretary calls for speedy and decisive international action on climate change (February 2007)
LEARNING SCIENCE AND LEARNING SCIENCE AND TECHNOLOGYTECHNOLOGY
• SCIENCE
– what climate is and how it works;
– how global climate has been changing and why;
– how it’s likely to change in the decades ahead;
• TECHNOLOGY
– the role of humans & their technology in causing climate change;
– technological options for mitigating climate change;
– technological options for adapting to it.

CHEMISTRY: carbon in fossil fuels and combustion
coal ≈ CH
oil ≈ CH2
natural gas ≈ CH4 + a bit more
so, e.g., burning oil entails…
CH2 + 3/2 O2 CO2 + H2O
Teaching Science / Biology
photosynthesis
6 CO2 + 12 H2O C6H12O6 + 6 H2O + 6 O2
(Trees are made of CO2 and water!)
respiration
C6H12O6 + 6 O2 6 CO2 + 6 H2O
anaerobic decomposition
C6H12O6 3 CO2 + 3 CH4

Research • Almost 1000 studies
dealing with different aspects of climate change have been conducted and published
• So… how do we make sense of all this?
Intergovernmental Panel on Climate Change (IPCC)
• Why was it created?– Created in 1988 by
the United Nations Environmental Program
– Established to provide policy-makers with an objective source of information about climate change
Intergovernmental Panel on Climate Change (IPCC)
• Who is in it?– Governments
• Members of the UN• Participate by naming
experts and reviewing the reports before they’re published
– Scientists• Close to 1000 scientists• Climatologists, ecologists,
atmospheric physicists, and others
Dr. Susan Solomon, a NOAA atmospheric chemist, an IPCC member and one author of IPCC summary
Intergovernmental Panel on Climate Change (IPCC)
• What do they do?– Review current scientific and technical
literature relevant to global climate change
– Provide reports on their findings at regular intervals
– Reports are designed to be politically neutral and of high scientific and technical standards
How do they create their reports?
It’s a multi-step process…
The assessments carried out by the IPCC have influenced global action on an unprecedented scale
1. First Assessment Report (1990) had a major impact in defining the content of the UNFCCC
2. The Second Assessment Report (1996) was largely influential in defining the provisions of the Kyoto Protocol
3. The Third Assessment Report (2001) focused attention on the impacts of climate change and the need for adaptation
4. The Fourth Assessment Report (2007) is creating a strong basis for a post Kyoto Protocol agreement
SOCIOPOLITICAL ACTIONIn order to MAKE RESPONSIBLE
DECISIONS and UNDERTAKE ACTION , students should be educated in CRITICAL THINKING and in the:
• ECONOMICS, POLITICS & POLICY OF CLIMATE CHANGE
– population growth & economic growth as climate-change drivers
– policy options and their impact
– actors and interests in the climate debate…
– finding a global climate-policy framework that is adequate, equitable, and attainable…

A Brief History of the Events Leading to the Kyoto
Protocol• COP 1, in March of
1995, saw the passage of the Berlin Mandate, which called for new negotiations on more detailed commitments for industrialized countries under the UNFCCC.
• On December 11, 1997 the Kyoto Protocol was officially adopted at COP 3 in Kyoto Japan.
• In 1998 a new round of negotiations on Kyoto were launched at COP 4 in Buenos Aires.
History (cont.)
• Negotiations on the rules of implementing the Kyoto Protocol resumed during COP 6 in Bonn, Germany, July 2001.
• Building on the Bonn Agreements negotiators at COP 7 (Marrakech, Morocco, October 2001) adopted a comprehensive package of decisions known as the Marrakech Accords.
What is the Kyoto Protocol?
• In general, a protocol is an international agreement that stands on its own but is linked to an existing treaty.
• More specifically, the Kyoto Protocol can be seen as an agreement, which supplements and strengthens the Framework Convention. Indeed, the Kyoto Protocol reaffirms the concerns and principles set out in the Convention and then builds on these by adding tougher, more specific commitments.
What is the Kyoto Protocol: 4 Main Elements
• The Kyoto Protocol consists of four main elements:
• 1. CommitmentsA. Specific emissions commitmentsB. General commitments
• 2. ImplementationA. Domestic policies and measuresB. Land use, land-use change and forestry sectorC. Joint implementationD. Clean development mechanismE. Emissions trading
What is the Kyoto Protocol: 4 Main Elements
• 3. ComplianceA. Facilitative BranchB. Enforcement Branch
• 4. Minimizing impacts on developing countriesA. Adaptation Fund
The European Union is a pioneer in the battle against
climate changeEU countries have set targets for 2020 to:
– Cut emissions by 20% (or 30% if agreed globally)
– Increase energy efficiency by 20%
– Generate 20% of energy from renewable sources
The EU is pushing for an ambitious new global pact to reduce emissions
EU: What can you do?
Simple everyday actions play a major role in the fight against climate changeSo…
– Recycle – Save hot water by taking a shower instead
of a bath (four times less energy)– Plant a tree, at school, in your garden or
neighbourhood
EU: What can you do?
• Use public transport, cycle, walk
• Don’t leave appliances on stand-by – use the on/off function of the machine
• Don’t leave you mobile charger plugged in when you are not charging your phone
