Your task
• Stick your seismograph trace in the middle of a
piece of A3 paper.
•Cut out the statements and arrange them around the
seismograph trace. Stick them down.
•Draw a line, using a ruler, to the place on the
seismograph that you feel the statement can be best
placed.
•In neat writing, next to the statement, write why you
have chosen to place it there on the seismograph.
• Give your piece the title ‘Seismograph’ and illustrate
the background, so that it looks like a city devastated
by an earthquake.
