With adult supervision, kids can make a homemade seismograph with a few arts and crafts materials. Before beginning, gather together a cardboard box, a plastic cup, some clay, some string, some small rocks, a piece of paper and a pair of scissors.Continue Reading
With the scissors, remove all the flaps from the top of the box. It should be completely open.
With a round skewer or a screwdriver, poke a hole in the center of the bottom of the cup. Then poke two holes opposite one another along the cup's rim.
Place the marker face-down through the bottom hole in the cup. Secure it in place with clay.
Poke two holes next to each other in the bottom of the cardboard box.
Thread the string through the two holes in the rim of the cup. Tie the string through the holes in the box so that the cup hangs level and the tip of the marker just touches the surface.
Fill the cup with small rocks, marbles or other heavy objects.
Place a piece of paper underneath the marker to record movement.
