hen carrying out
investigative work
in the primary
school, we often
consider how familiar the children are with the context. This
usually means considering the
practical and life experiences the
children have already had. However,
it is also valuable to consider the
children’s literary experiences.
Think about all the stories, novels,
folk tales and nursery rhymes that
children know inside out. Stories
such as the Three Little Pigs ,
Cinderella and Humpty Dumpty are
easily used as the starting points
for investigations with younger
children: a house of straw might
not be much use against the big
bad wolf – but which pig would
fare best in a rainstorm? Are glass
slippers really practical? What is
the maximum safe fall distance
for a raw or cooked egg?
However, one of the problems
with this approach is that it is
inherently limited: it is only
possible to see how some stories
might be used for some investigations. Whilst this may
provide a few valuable starting
points, many teachers will look at
the curriculum that they are
teaching and find that it is
difficult to decide just what story
might provide just the right
stimulus.
Time to get creative:
writing sequels
The solution is really quite simple.
If the story that you need doesn’t
exist, you can write it yourself. If
the thought of writing a short
story for a specific purpose seems
somewhat daunting, consider
how often you ask your children
to do exactly that!
Rather than inventing stories
from scratch, a useful starting
point is to consider the concept
of the ‘sequel’. That is, write a
short story that includes
characters and situations that are
already well known, both to you
and the children. In the example
given here (Box 1), based on the
story of Goldilocks and the Three
Bears, the setting is the three bears’
cottage just after Goldilocks has
run off. I needed a story about
dissolving with as many
uncontrolled variables as
possible, suitable for year 4
children (8/9 year-olds) working
on fair testing. The idea of sugar
in tea seemed obvious. Then I
needed to consider who, in
children’s literature, might be
making more than one cup of tea
– a family grouping. And so it
went from there. Remember that
it is important to consider the
children’s literary preferences. The
story that I came up with features
the three bears, but if I was writing
this for year 6 children (10/11
year-olds) Daddy Bear, Mother
Bear and Baby Bear could easily
become Harry, Ron and Hermione
– the young wizards in the Harry
Potter stories.
Using stories to develop
science skills
As I said, this story was written to
help year 4 children understand
the need for controlling variables.
The first thing to do
is to get the children
to consider what
Baby Bear means
when he says he likes
one cup of tea and not
the other. Once it is
established that this must be
because of the sweetness (that
is, how well or how much the
sugar has dissolved – the
dependent variable), the children
can go on to examine all the
