KS3 SCIENCE - KS3 PHYSICS QUIZZES
Doc B's revising for KS3 SCIENCE - Doc Brown's Physics I appreciate SAT levels have gone, but I hope these KS3 physics Quizzes will still be of some use. Although I've already produced some combined KS3 physics quizzes, I welcome suggestions from teachers so I may produce useful compilation KS3 physics quizzes suitable for any school doing KS3 physics and any KS3 physics scheme of work. Copying of the KS3 physics quizzes is NOT permitted, but you can printout the KS3 physics questions to use in class or for homework. The first part of the page is the most important - the links to the KS3 Physics multiple choice quizzes. The rest of the page is lots of guidance for doc b to help design the most useful KS3 Physics quizzes For after KS3 SCIENCE ...

Doc Brown's Revision KS3 Science KS3 PHYSICS Unit 7I Energy resources
KS3 Physics: About the unit
In this unit pupils:
• are
introduced to the concept of energy in the context of fuels as convenient and
therefore valuable sources
• consider
the nature and origin of fossil fuels and renewable sources of energy and how
their use has implications for the environment
• consolidate
and extend their ideas about energy resources for living things: food for
people and sunlight for plants
• link
the energy resources to the role of the Sun as the ultimate source of most of
the Earth’s energy resources
In scientific enquiry pupils:
• recognise
hazards and take safety precautions
• decide
what variables are relevant and how to control these to make fair comparisons
• consider
the reasons for repeating measurements and observations
• use the
Bunsen burner and thermometers safely and effectively
• make
measurements of volume, mass and temperature
• investigate
the energy resource in foods, controlling relevant variables
KS3 Physics:
Note on the teaching of energy
This unit provides an introduction to energy
through the idea of foods and fuels as energy resources. The term ‘resource’ is
used in preference to ‘source’ to try to encourage the idea that energy is not
just a kind of stuff, like fuel. Energy transfer is associated with change, in
particular changes that can perform useful tasks, as a first step towards more
formal understanding. This enables pupils to make connections between
apparently disparate phenomena, as contexts are drawn from across the sciences,
eg burning fuel, movement, eating food
and plant growth. Pupils can begin to distinguish energy from stuff (the
energy resource) and from linked concepts, eg
force, power (the rate of
transferring energy) and activity. A common misconception is that
activity gives you energy because it makes you healthier – and so more able to
do more activity.
KS3 Physics: Where the unit fits
in
This unit introduces pupils to a topic which
may be new to them, although it has links with work done in key stage 2. It
builds on ideas introduced in unit 6A ‘Interdependence and adaptation’ (green
plants need light), unit 6D ‘Reversible and irreversible changes’ (burning),
unit 6G ‘Changing circuits’ (electrical conduction) and unit 4C ‘Keeping warm’ (temperature;
thermal insulation) in the key stage 2 scheme of work.
In unit 8I ‘Heating and cooling’, pupils will
study energy transfer and change of state, and use particle explanations. In
unit 9I ‘Energy and electricity’, pupils will study energy transformations and
energy conservation.
This unit relates to unit 7A(ii) ‘Understanding
materials (resistant materials)’ in the design and technology scheme of work.
There are opportunities for citizenship education in this unit, in dealing with
energy-supply issues.

up in the circuit, energy is. This work focuses on distinguishing between two
abstract concepts: electricity as ‘flowing stuff’ and electrical energy as
something that is identified by input and output effects. Its effects are
associated with the brightness of bulbs and its origins in the voltage rating
of batteries. There are necessary simplifications in the treatment, as
appropriate to this early unit.

Doc Brown's Revision KS3 Science KS3 PHYSICS Unit 8I Heating and cooling
KS3 Physics: About the unit
In this unit pupils:
• recognise
the need for a temperature scale
• learn
to distinguish between heat (as energy) and temperature
• learn
about mechanisms of heat transfer: conduction, convection and radiation, and
apply this to familiar contexts
• learn
about expansion and change of state in solids, liquids and gases
• use the
particle model to explain conduction, convection and change of state
In scientific enquiry pupils:
• draw
and interpret line graphs from data collected
• carry
out a survey of people’s perceptions of common temperatures
• investigate
the effectiveness of different forms of insulation, controlling relevant
variables
Note on the teaching of energy This unit considers the idea that energy transfer results from a difference in temperature. This is an important concept, as most changes are a result of differences and energy changes are associated with them, eg a raised object falls, transforming its potential energy to kinetic energy. The unit also helps pupils distinguish heat (energy) from temperature. There has been much debate about the use of the word ‘heat’ for energy. The risk is that it might support the idea of a separate kind of stuff – as was current in science before the work of James Joule in the nineteenth century. It is used here in contexts which should avoid that misconception. The unit applies ideas of moving particles to explain the transfer of heat (energy) by conduction and convection, thus clarifying that, in this context, heat is a kind of movement. Particle models are also used to explain how matter changes state when energy is added or removed, so this unit needs to follow unit 7G ‘Particle model of solids, liquids and gases’ and unit 7H ‘Solutions’.
KS3 Physics: Where the unit fits
in
This unit uses ideas developed in the key stage
2 programme of study. It builds on ideas introduced in unit 4C ‘Keeping warm’
and unit 5D ‘Changing state’ in the key stage 2 scheme of work.
In unit 7I ‘Energy resources’, pupils will have
identified that when fuels burn they release energy and have noted the
consequent rise in temperature.
In unit 7G ‘Particle model of solids, liquids
and gases’, pupils will have encountered the particle model of matter. In unit 9I ‘Energy and electricity’, pupils will study energy transformation and energy conservation.
Expectations
At the end of this unit
in terms of scientific enquiry
most pupils will: plan
a survey of perceptions of temperature, using an appropriate sample; plan an
investigation into methods of reducing heat loss; carry this out using ICT for
recording temperature data and relate findings to practical implications;
select effectively information from secondary sources to compare methods of
preventing heat loss in houses; collect and interpret temperature data from a
substance changing state
some pupils will not have made so much progress and will:
use thermometers safely; present survey data
using a chart or table; identify and control key variables in an investigation

Doc Brown's Revision KS3 Science KS3 PHYSICS Unit 9I Energy and electricity
KS3 Physics: About the unit
In this unit pupils:
• explore
a range of useful energy transfers and transformations
• discuss
the use of electricity as a convenient way to transfer energy to do useful
things
• associate
the concept of voltage with the transfer of energy in a circuit
• investigate
the voltage of cells
• study
how electricity is generated, with reference to environmental impacts
• use the
principle of conservation of energy to identify ways in which energy is
dissipated during transfers
In scientific enquiry pupils:
• use
models to explain observations relating to electric currents
• use
scientific knowledge to frame a question for investigation
• measure
voltage in circuits
• identify
patterns in the measurements of voltage in series circuits and use these to
draw conclusions
Note on
the teaching of energy
This unit presents a range of useful changes
and helps pupils to use the language of energy transfer and transformation in
describing them. The word ‘transfer’ is used to describe energy’s change of
place; the word ‘transform’ is used to describe a change in the way energy
shows itself, eg from electrical energy
to light.
The unit focuses on how transfers and/or
transformations of energy by electricity are important in everyday life. It
explains these simply and looks at some of the consequences of the electricity
supply industry. The unit covers the ideas of dissipation or ‘wasted’ energy
and the conservation of energy. In extending the concept to these contexts,
simplifications appropriate to year 9 pupils have been made. Pupils need labels they can use when they come across energy, eg electrical energy, light and heat. This is a first step in developing understanding. Teachers should help pupils recognise that they need to go further in some contexts, eg that ‘spring energy’ is the result of the elastic properties of the metal the spring is made of, and so could be called ‘potential energy’ because of its compressed position. It would be inappropriate, at this stage, to develop this further and associate the energy with the electric bonding forces between the atoms of the spring. Formal definitions of work, kinetic energy and potential energy are also best left until key stage 4 for most pupils.
KS3 Physics: Where the unit fits in
This unit builds on work on electricity and
energy in units 7I ‘Energy resources’, 7J ‘Electrical circuits’ and 8I ‘Heating
and cooling’. It relates to work on the reactivity of metals in unit 9F
‘Patterns of reactivity’ and work on fuels in unit 9G ‘Environmental
chemistry’. It relates to unit 9D ‘Using control for electronic monitoring’ in
the design and technology scheme of work, and to unit 18 ‘Twentieth-century
conflicts’ and unit 20 ‘Twentieth-century medicine’ in the history scheme of
work.

goes to waste

a circuit; recognise that although the total energy in a system is conserved,
energy can be dissipated; use ‘power ratings’ in comparing the costs of using
different electrical appliances; link the function of an electric generator to
