Frequently Asked Questions (FAQ)
Q: How do I ensure safe usage of the flying fan
experiment?
A: Make sure to keep your head out of the way when initiating
the flying fan experiment to avoid any accidents.
Q: Why does the motor not rotate when the LED is connected in
series?
A: The LED prevents the motor from receiving the required
current, causing it not to rotate. This setup demonstrates the
concept of current flow in a circuit.

PREFACE CHALLENGE
The land, sea and air transport project kit contains exciting experiments which are designed to teach the principles of electronics to children of ages 5 years and upwards.
The easy- to-handle components snap together to create a huge number of different
circuits on the base board. All wires are secured within the components, so the
kit is completely safe and amazingly simple to operate. The circuits are
23
activated by magnet, touch, light and sound. The kit contains various
electronic experiments, encompassing light motorised movement and
brilliant sound effects.
Children of all ages will quickly learn how to set up the circuits and will be
captivated by the results of their experiments. Older children will increase
their knowledge of electronics by using their imaginations to design, their
very own circuits.
12
An understanding of electronics is a vital part of a child’s scientific
education. The land, sea and air transport project kit provides a
comprehensive understanding of electronic circuits, in a fun and practical
way.
