Domremy Program – Stage 6 Physics 8.5 The Cosmic Engine Program – Updated August 2007
COURSE:
Preliminary Physics
MODULE:
8.5
Page 1
The Cosmic Engine
SUGGESTED TIME: 28 indicative hours.
CONTEXTUAL OUTLINE
The Universe began with a singularity in space-time. After the initial explosion, the Universe started to expand, cool and condense, forming matter. As part of
this ongoing process the Sun and the Solar System were formed over 4x109 years ago from a gas cloud which resulted from a supernova explosion. The
condensing gas and dust that formed the Sun and the planets contained all its original elements. The planets were formed when matter came together under the
influence of gravity.
This module increases students’ understanding of the history of physics, implications of physics for society and the environment and current issues, research and
developments in physics.

Outcomes
P4 describes applications of
physics which affect society or the
environment
research
P6 describes the forces acting on
an object which cause changes in
its motion
P7 describes the effects of energy
transfers and energy
transformations
P9 describes the relationship
between force and potential
energy in fields
P10 describes theories and
models in relation to the origins
of matter and relates these to the
forces involved
P12 discusses the validity and
reliability of data gathered from
first-hand investigations and
secondary sources (P12.2a-c;
P12.3a-d)
P13 identifies appropriate
terminology and reporting styles
to communicate information and
understanding in physics (P13.1ag)
P14 draws valid conclusions from
gathered data and information
(P14.1a-h; P14.2a-d; P14.3a-c)
Students Learn About / Learn To:
 identify the nature of emissions reaching the Earth from
the sun
 describe the particulate nature of the solar wind
 outline the cyclic nature of sunspot activity and its
impact on Earth through solar winds
 describe sunspots as representing regions of strong
magnetic activity and lower temperature
 identify data sources, gather and process information and
use available evidence to assess the effects of sunspot
activity on the Earth’s power grid and satellite
communications by

Teaching / Learning Strategies
Suggested Time: 1 hour
 extract information from visual and spoken material by
viewing, taking notes and summarising Episode 5 from the
Planets series, Star1, to identify emissions from the sun and
to describe sunspots and solar winds (lit, ESL)¨
 collate information obtained from internet sites2 and the
video above and other relevant sources3 to determine the
effects of sunspot activity on the Earth's power grid and
communication4 (KV, G & T, tech)
 produce a written summary about the effects of sunspot
activity to evaluate the relevance of the collected secondary
information, remembering to acknowledge all sources of
information (lit, ESL)
 using the information already gathered and collated, draw a
diagram5 to represent the path of solar winds as they flow
around the Earth (the Earth's magnetosphere).
