Sustainability
in the Science Curriculum
The
major issue currently facing the Earth (and humans) is the lack of
recognition of the interconnection between humans and the biosphere,
the atmosphere and other systems of the planet and the inappropriate
technologies currently in use. Humans have overused and polluted the
biotic and abiotic resources of the Earth.
In
terms of building environmental literacy and responding to the major
issues facing humans, it would be wise to develop a progression in
underpinning ideas, skills and values in:
-
Living
things / Biology - global threats to biodiversity and consequent actions
to be taken, ecosystem services and disturbance to these,
interconnection of all life on earth and their connections with
the abiotic environment, exponential human population growth and
accelerating use of resources, building skills and experiences
in the natural environment, making environmentally responsible
choices.
-
Energy
/ Physics
- environmentally appropriate technology choices especially in
energy production, efficiency and use, choosing low energy
options, replacement of carbon-based with renewable, non-nuclear
energy sources.
-
Chemistry / matter – environmentally appropriate cradle to grave
processing, use and disposal and selection of materials (green
chemistry), minimising waste / pollution.
-
Earth
– sustainability and ecological footprint in resource planning,
development and use, protection of assets – water, topsoil, air,
bio and habitat diversity, the connectivity between the
biosphere and the other earth systems, recognition of important
reserves eg of water, biodiversity, climate change.
Example: Living things with Living things / Biology – detail of concepts for curricula inclusion
The
following interconnected ideas or concepts (not in any order)
contribute to an understanding in Living things / biology:
- Biological systems
- Biodiversity
- Evolution – variation, isolation, selection, adaptation and as a central
idea for biodiversity
- The impacts of humans and the related ideas of sustainability.
- Plants as the basis of food
- Hands-on exploration and investigations of the natural environment
- Anthropocene period
- Ecosystem services
- Biodiversity at the genetic, organism and ecosystem levels and the idea
of hotspots
- Uniqueness, geographic distribution and endemism of particular
ecosystems
- Threatened species, communities and threatening processes
- Ecosystem persistence / resilience / succession / tipping points
- Survival of organisms and ecosystems
- Plants as the basis of food and oxygen production and the sun as the
energy source.
- Human overuse of the environment, pollution and rapid change,
conservation,
- Human plunder or destruction of habitat of migrating species have
consequences for those species and all ecosystems visited by those
species.
- Consequences of accelerating human population growth (exponential) and
consumption of resources
Indigenous perspectives on management of environments.

How to start using these curriculum ideas in the classroom:
-
Choose a starting focus for your country, an appropriate student age
group and an educational strategy.
-
For example:
-
Threats to Wildlife.
Place – Australia. -
Threatening processes. Important concepts that exemplify issues that
affect Australians and affect the integrity of Australia’s unique,
endemic wildlife are threatening processes. -
Student group 9-12 year olds. -
Educational strategy – cause and effect, interactions, systems;
using field studies, hands-on activities, simulation, research,
mapping/graphing, classification keys, simple food chain activities.
-
Cause and effect relationships and interactions understanding can be
through concepts involving threatened species and threatening
processes. In 9-12 year olds, that could be represented by the
effect on individuals, species and ecosystems of introducing feral
organisms (eg cane toads, cats, rabbits and foxes) and also the
effect of wildfire as a threat to organisms and ecosystems. These
cover biotic and abiotic threats. Threatened Australian iconic
species could be studied and what causes them to be under threat.
-
Each country would have set of threats that are critical to the
survival of their biodiversity or ecosystem services. A science
curriculum could start with a focus on these. A Glossary of Terms that may be useful in teacher understanding of
the current environment is attached in Appendix A.
Pedagogy
Pedagogical approaches should attempt to build connections between
the child and the environment. Activities in the natural environment
(with care for the environment as a strong message) is an essential
pedagogy for this area, with hands-on approaches that optimise
engagement, ownership, inquiry and emotional attachment by the
children to the environment.
APPENDIX A
Glossary of
important terms and ideas for a Sustainability in Science Curriculum
Anthropocene:
The most recent period of Earth’s
history, generally referring to the past two centuries,
characterized by human activities having a substantial impact on
global ecosystems and climate.
Anthroposhere:
A division of the Earth referring
to that part of the environment made by or strongly shaped by human
activities.
Complex System:
A set of multiple, diverse, and
interacting components whose overall (system level) behavior is not
predictable from measurement of the components alone. Complexity
arises due to nonlinear responses and feedbacks among the system
components. Complex systems are typically also complicated systems
in that a large number of different components may be involved and
operate over a range of different spatial, temporal, and
organizational scales.
Complex Adaptive Systems:
Complex systems that include
components having the capability to learn from experience, e.g.,
living organisms or human systems, and change in response to overall
system level behavior.
Ecosystem Services:
The resources and services
provided to humans from natural ecosystems; these can be subdivided
into provisioning (e.g., oxygen, absorption of carbon dioxide,
water, food), regulating (e.g., flood control), supporting (e.g.
pollination), cultural (e.g., recreation), and preserving (e.g.,
resiliency to disruption) services.
Interdisciplinary Research:
The integration of approaches,
concepts, and data from multiple science and engineering disciplines
to advance understanding and address problems in a fashion that is
more comprehensive and synthetic than is possible using only the
perspective of a single discipline.
Resiliency:
The ability to recover from
disruption, or the rate of its return, to some prior state following
a perturbation.
Sustainability:
The ability to continue or
persist into the long-term while maintaining a particular set of
characteristics or functionalities. Sustainability may involve
components or mechanisms that promote resiliency but is a broader
concept than just recovery from perturbation.
Tipping Point:
The point at which a system
undergoes a drastic change from one state to a very different one.
Complex systems involving positive feedback among components with
non-linear rates of change are susceptible to tipping point
phenomena. The term was made popular by Malcolm Gladwell in his 2000
book “The Tipping Point: How Little Things Can Make a Big Difference”,
which discusses the concept with respect to change in human behavior
and social systems.
