BASE CiRCUiT wiTH LESS pOwER
Assemble the base circuit with the bulb and only use one battery (see
picture page 7). You can see the loss of power because the bulb only
just lights up.
BASE CiRCUiT wiTH fLYiNG SAUCER AND LESS pOwER
Replace the bulb used in the last activity (Activity 4) with the flying
saucer. Turn on the switch and observe. What happens? The motor
does not go as fast and it is almost impossible to make the flying
saucer take off properly as there is not enough power.
WARNING!
Make sure you have plenty of space around you while doing this
activity. Carry out this activity well away from breakable objects. Keep your face
away from the saucer when it is moving. Do not point the flying saucer at people,
animals or objects. The presence of an adult is recommended while carrying out this
activity.
BASE CiRCUiT wiTH NEwTON’S OpTiCAL
DiSC AND LESS pOwER
Replace the flying saucer (Activity 5) with Newton’s optical disc
and observe carefully. One battery does not have enough power to
make the colours disappear.
Note:
If your batteries are very strong, Newton’s optical disc might
spin so fast that the colors disappear.
