U1: Historical Development
of Scientific Theory
 Scientists conduct experiments, collect
results, observe, and draw conclusions.
 Knowledge – used to develop general
C1: principles/theories.
 Theories - observed phenomena and
U1: Historical predict unobserved phenomena.
 New knowledge evolves these models.
Development of  Science - way of thinking about the
Scientific Theory universe.



Sample
U2: Designing a Scientific
Investigation
 Step 1: Identify problem & formulate question
U2: Designing a
Scientific Investigation
 New scientific knowledge, despite being
based on experimental evidence, isn't
always accepted.
 New knowledge - sound experimental
evidence and support from other
scientists.

to answer the problem.
 Step 2: Use question to formulate hypothesis.
 Step 3: Design a procedure.
o Identify variables - changed, measured,
and controlled.
o Decide on procedure to change
independent variable.
o Collect apparatus, equipment, and
resources.
o Include methodical/safety precautions.
 Step 4: Carry out procedure - collect data.
 Step 5: Arrange recorded data in a table.
 Step 6: Analyse data to draw
conclusions/evaluate the procedure.
 Step 7: If conclusions confirm hypothesis -
investigation is complete. If rejected - new
hypothesis can be formulated.
