A. SAFETY MESSAGES
1. Please read through all the instructions and keep them since they contain important information. 2. Adult assistance and supervision
are required. 3. This kit is intended for children 5 years or older. 4. This kit and its finished product contain small parts and small balls
which may cause choking if misused. Keep away from children under 3 years old. 5. To prevent possible short circuits, never touch the
contacts inside the battery case with any metal. 6. Only install batteries after the kit is assembled. Adult supervision is required.
B. USE OF BATTERY
1.
Requires one 1.5V AAA battery
(not included). 2. For
best
results,
always use a fresh battery.
3. Make
sure you insert the battery with
the correct polarities.
4.
Remove the battery from the kit when not in use. 5. Replace an
exhausted
battery
straight
away to avoid possible
damage
to the kit. 6. Rechargeable batteries must be removed from the kit before recharging. 7. Rechargeable batteries should be
recharged under adult supervision.
8. Make
sure that the supply terminals in the battery case are not short circuited.
9. Do
not attempt to
recharge non-rechargeable batteries.

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.
