Marble sculptures are very fun to make. You can also learn from them too. We enjoyed them so much, that we thought you would like to learn how to make them also. Here are the instructions:
Marbles Pipe insulation
Heavy paper strips Plastic pipes
Scissors Cardboard Tubes
1. Tape paper strips around the edge of the table to
keep the marbles from rolling off.
2. Place other sculpture materials on the table and begin
for sculpture marbles to roll through, into, and over.
3. Use inclines and connecting tracks and tunnels for
marbles to follow. Playdough can be used to support tubes, pipes,
cans as they go through the sculpture.
4. Send marbles through the sculpture.
Science Concept: A marble is a smooth round
object that rolls easily. Once the marble starts moving it will keep
moving for a long time or until something stops it. This demonstrates
a law of physics called INERTIA, which states that an object in motion
will remain in motion. Other laws can get in the way of the rolling
marble like those of GRAVITY and FRICTION. Gravity is the force that
pulls all things toward the earth and causes the marble to roll down the
inclined ramps. Friction is the rubbing together of materials like
the marble against any surface which slows down the marble.
