A
student
has
five
different
objects,
A
to
E.
They
are
all
made
of
solid
glass.
He
picks
up
each object.
Then
he
predicts
that
four
of
the
objects
are made
of
the
.
same
sort
of
glass
but
that one is
made
of
a different
sort
of
glass.
He
measures
the mass and

of each
object.
He
uses

A student wants
to measure
the brightness
of
different
parts
of
a
room.
She
uses
a
light
dependent
resistor
(LDR).
This
resistor
has a
high
resistance
when
it
is
in the dark.
Its
resistance
is
low when it
is in
the
light.
The
student
fits
the
LDR
in
one end
of
a
black
plastic
tube.
The
diagram
shows
how
she
includes the
LDR
in
an
electrical
circuit.
