13. Place all the metal balls (part N) in the spiral track. They will roll along the channel in the base until they reach the turning wheel.

14. Turn on the marble machine. One by one the balls will be raised by the turning wheel and run around the spiral track.

E. TROUBLE SHOOTING

If the motor doesn't run: check that the bare wires are touching the terminals and that you have used a fresh battery.

If the turning wheel turns in the wrong direction in step 14: check that the wires are the correct way round in step 6.

F. HOW DOES IT WORK?

The battery operates the motor, which turns the worm gear on its shaft. This turns the small gear slowly, which turns the large gear. The

large gear turns the drive gear which operates the turning wheel. When a slot in the wheel passes the bottom of the track, a ball falls into

it. When the ball reaches the top position it can fall out and enter the spiral. Gravity makes the ball roll around the spiral until it reaches

the hole at bottom.

G. FUN FACTS

• The Marble Machine is an example of a machine called a marble run.

• When the ball leaves the wheel it rolls around the spiral instead of straight towards the centre. The shapes of the spiral means that

gravity keeps the ball rolling downwards as though it were on a long spiral ramp.

• The ball drops lower and lower on the spiral because friction gradually slows it down.

• If there were no fricton between the ball and the spiral, the ball would keep going around in a circle, like a planet orbiting a star.

• There are lots of different types of energy, including heat, light and sound.

• As a marble travels around the marble machine it has two different types of energy: gravitational potential energy and kinetic energy.

• Gravitational potential energy is the energy that an object has because of its vertical position. The higher up and object is, the more

potential energy it has.

• Kinetic energy is energy that an object has because it is moving. The faster an object is moving, the more kinetic energy it has.

• When a marble is moved up by the wheel it gets potential energy. Then when it rolls down the track the potential energy is converted to

kinetic energy. This is an example of an energy change, where one type of energy changes to another.

• When a marble reaches bottom of the track and stops, all its energy is gone. The energy it had gets changed into heat because of

friction, and also sound.

• Energy is needed to give the marbles potential energy at the start of the run. This comes from chemical energy in the batteries that

power the motor.
