Task Outline
Students investigate a contemporary example of how science interacts with society. This may
focus on one or more of the key applications of science as a human endeavour described
throughout the course outline, or any other application that connects to the topics covered
in Stage 2 Physics.
You are to select and explore a recent discovery, innovation, issue, or advancement linked to
one of the topics in Physics. You will then need to analyse and synthesize information from
different sources to explain the science relevant to the focus of the investigation, show its
connections to science as a human endeavour, and develop and justify your own conclusions.
Possible starting points for the investigation could include, for example:
• the announcement of a discovery in the field of physics
• an expert’s point of view on a controversial innovation
• a TED talk based on a development in physics
• an article from a scientific publication (e.g. Cosmos)
• public concern about an issue that has environmental, social, economic, or political
implications
• changes in government funding for physics-related purposes, e.g. for scientific
esearch into decommissioned satellites and spent rocket stages, various forms of
medical imaging, quantum computers and extremely high data transfer, ring laser
guidance systems and their application for accurate aircraft navigation, use of nuclear
isotopes for industrial or medical applications, monitoring changes in global
temperature
• ‘blue sky’ research leading to new technologies.
Why Do We Look at Science as a Human Endeavour?
The science as a human endeavour strand highlights science as a way of knowing and doing,
and explores the purpose, use, and influence of science in society.
By exploring science as a human endeavour, students develop and apply their understanding
of the complex ways in which science interacts with society and investigate the dynamic
nature of physics. They explore how physicists develop new understanding and insights and
produce innovative solutions to everyday and complex problems and challenges in local,
national, and global contexts. In this way, students are encouraged to think scientifically and
make connections between the work of others and their own learning. This enables them to
explore their own solutions to cu
ent and future problems and challenges.
Students understand that the development of science concepts, models, and theories is a
dynamic process that involves analysis of evidence and sometimes produces ambiguity and
uncertainty. They consider how and why science concepts, models, and theories are
continually reviewed and reassessed as new evidence is obtained, and as emerging
technologies enable new avenues of investigation. They understand that scientific

advancement involves a diverse range of individual scientists and teams of scientists working
within an increasingly global community of practice.
Students explore how scientific progress and discoveries are influenced and shaped by a wide
ange of social, economic, ethical, and cultural factors. They investigate ways in which the
application of science may provide great benefits to individuals, the community, and the
environment, but may also pose risks and have unexpected outcomes. They understand how
decision-making about socio-scientific issues often involves consideration of multiple lines of
evidence and a range of needs and values. As critical thinkers, they appreciate science as an
ever-evolving body of knowledge that frequently informs public debate but is not always able
to provide definitive answers.
The key concepts of science as a human endeavour underpin the contexts, approaches, and
activities in this subject, and must be integrated into all teaching and learning programs.
Science informs public debate and is in turn influenced by public debate; at times, there may
e complex, unanticipated variables or insufficient data that may limit possible conclusions.

Key Concepts of Science as a Human Endeavour
The key concepts of science as a human endeavour in the study of Physics are:
Communication and Collaboration
• Science is a global enterprise that relies on clear communication, international
conventions, and review and verification of results.
• Collaboration between scientists, governments, and other agencies is often required
in scientific research and enterprise.
Development
• Development of complex scientific models and/or theories often requires a wide
ange of evidence from many sources and across disciplines.
• New technologies improve the efficiency of scientific procedures and data collection
and analysis. This can reveal new evidence that may modify or replace models,
theories, and processes.
Influence
• Advances in scientific understanding in one field can influence and be influenced by
other areas of science, technology, engineering, and mathematics.
• The acceptance and use of scientific knowledge can be influenced by social, economic,
cultural, and ethical considerations.
Application and Limitation
• Scientific knowledge, understanding, and inquiry can enable scientists to develop
solutions, make discoveries, design action for sustainability, evaluate economic,
social, cultural, and environmental impacts, offer valid explanations, and make
eliable predictions.
• The use of scientific knowledge may have beneficial or unexpected consequences; this
equires monitoring, assessment, and evaluation of risk, and provides opportunities
for innovation.

Assessment Submission Information
Based on your investigation, you will need to prepare a scientific report, which must include
the use of scientific terminology and:
• an introduction to identify the focus of the investigation and the key concept(s) of
science as a human endeavour that it links to
• relevant physics concepts or background
• an explanation of how the focus of the investigation illustrates the interaction
etween science and society
• a discussion of the purpose, potential impact, or application of the focus of the
investigation, e.g. further development, effect on quality of life, environmental
implications, economic impact, intrinsic interest
• a conclusion
• citations and referencing.
The scientific report should be a maximum of 1500 words if written, or a maximum of 10
minutes for an oral presentation, or the equivalent in multimodal form.
This report could take the form of, for example:
• an article for a scientific publication
• an oral or multimodal scientific presentation.

She Task: Solar Sails
Introduction
Interplanetary spaceflight incorporates space travel that is ca
ied out using a space probe within a single planetary system and can either be automated or with a crew between the planets and the pool of stars in that galaxy. Novel space propulsion techniques based on electric rockets that function on low thrust play a vital role in the steady acceleration of robotic probes to attain velocities that chemical energy-based rockets cannot achieve. Cosmic robotic explorers utilize convoluted gravitational force to accelerate and propel. These spacecraft are designed to be unaccompanied by rockets that are set in motion at the expense of heavy fuel and the force of gravity. The concept of Solar Sails moving in the solar system war deeply studied by J.C. van der Ha, V.J. Modi, R.L. Staehle and E. Polyakhova. These studies enabled the development and understanding of the potentialities associated with the pressure of light carefully incorporated with the appropriate spacecraft technology for a variety of space missions, ranging from the ones in the Earth to Moon space to the missions near the interstellar medium and beyond (Vulpetti, Johnson and Matloff, 2015).
Solar-photon sails or Solar Sailing refers to a technology that establishes a new class of space science and interplanetary exploration missions that earlier were considered impossible due to arduous propulsion operations. The term solar wind refers to the stream of charged particles emitted by the sun that are mostly hydrogen and helium but in the case of Solar Sails, the ‘wind’ that blows the sail is a gentle push from the ever-present sunlight which eventually accelerates the space probe to speeds that are far above the achievable speeds we obtain using chemical and electric rockets. This space-sailing technology employs sunlight that is reflected from its surface such that the resultant radiation pressure or thrust leads to effective propulsion of the spacecraft eliminating the need for costly and heavy fuel. Solar sailing is a revolutionary method of propulsion for spacecraft as it comprises of a large reflective foil on a solar sail that captures the momentum of light from the sun and utilizes it to propel the spaceship forward through space. This concept was first proposed in 1921 by Tsiolkovsky, who wrote of using the pressure of sunlight to attain cosmic velocities. However, the term “solar sails” became popularized from a short story “Sunjammer (The Wind from the Sun)” by Arthur C. Clarke in May 1964.
The first application of photon propulsion techniques was performed by NASA in 1974 when the Mariner 10 Spacecraft experienced problems in its control system. When the Mariner 10 was moving off course, the NASA team controlled the angle of the solar panels relative to the sun to co
ect the problem without the usage of fuel (Edwards & Hollerman, 2002). Solar sailing can be 100% photon propulsive reliant, unlike traditional spacecraft that use chemical rockets burning enormous amounts of fuel to change speed or direction (What is Solar Sailing? 2021).
Solar Sails are constructed using lightweight reflective materials such as Mylar (Bi-axially oriented- polyethene terephthalate) or Polyamide coated with reflective materials. Cobalt alloy booms extend out and unwind the sails with the help of 4 triangular sails that are merely 4.5 micrometres thick until these reflective sails are efficiently exposed to the sun. The speed at which a solar sail can reach depends upon its size and mass but interestingly, sail with a larger surface area will capture more photons and therefore obtain an increased propulsive force.
Presently, there is only one spacecraft; LightSail 2, that is...
