CONCEPTS
I can understand that…
QUESTIONS
Evidence

I can answer…
Can a theory be disproved?
We can accumulate evidence for
theories by using them to make
predictions
Can energy use bring
ecological disaster?
How can a small increase in
the carbon dioxide levels in
the atmosphere affect Earth’s
temperature?
Scientific theories are not fixed or
unchangeable
Some theories do not allow us to
make precise predictions
SKILLS
FACTS
The atmosphere and the climate have changed
throughout the Earth’s history, but are changing
more quickly at the moment
The average temperature of the Earth has risen over
the last century. This has resulted in physical
changes to the planet
The evidence at the moment shows that human
activity IS having an effect on the climate

Evidence

Where do we get energy
from?

are there
What is renewable and nonrenewable energy?
Everything that happens has to
involve energy source
What is nuclear power?
Renewable energy sources are
often intermittent and unreliable

QUESTIONS
Evidence

FACTS
Many factors both personal, social, ethical, cultural
and scientific effect decisions
Decision making arguments need matched to a
specific set of circumstances
Economic factors figure strongly in decision making
arguments
Evidence

What influences leaders in
making decisions?
Scientific evidence is important,
but rarely provides complete
answers for real-life decisions

I can answer…

Can decisions be made that
benefit both people and the
environment?
When making decisions, can
the views of all people be
given equal weight?
