The Mystery of the Magic Newspaper
My fish and chip shop still wraps up chips in newspaper. This is to keep them hot.
My Gran always comes home from town on the bus. She wraps her tubs of ice cream
up in newspaper to keep them cold and stop them melting.
How does the newspaper know what to keep hot and what to keep cold?
Paper isn’t a good insulator
The newspaper is mostly white so it reflects
the heat from the chips back inwards
Black ink radiates heat more quickly than
the white paper
My Granny’s surname is Potter
The newspaper is mostly white so it reflects
the cold from the ice-cream back inwards
Insulators stop heat energy travelling from
one place to another
Air is a good insulator
Ice cream melts when the cold leaks out of
it and the heat leaks in
Paper is made from wood pulp. Newspaper
includes lots of recycled paper
The newspaper is much more effective if
there is more than one layer.
The newspaper stops heat travelling by
convection and conduction
The number of photographs on the paper
doesn’t affect the insulating properties.
When my Gran goes to town in the winter
she always wears a vest, a blouse, a
cardigan and a coat.
Heat travels by convection, conduction and
radiation.
Tick any important statements that can explain how the newspaper is working
Cross any unimportant statements or statements that are false
Put a T on any statements that are true but are not relevant
Explain how the newspaper works and include evidence from the statements.
