Watch the video to encourage children's interest in electricity.
Let children watch the videos as a reward when they have finished their work
Let students experiment with the circuit simulation
Discuss saving Eddy as a way of encouraging energy saving.

Ask the chilldren to count how many items are on standby in their house e.g. still switched on at at the plug but turned on.
Calculate the following:
If a light uses 100 W (Watts) in one hour = 100 W/hr
If equipment on standby uses 1 W for a year. Calculate which uses the most electrons?
( 1 x 24 hours/day x 365 days/year = 8760 W)
Explain that phone chargers still use energy even when the phone is not connected to the charger. Ask the children feel the temperature of the mobile phone charger. They will notice it is warm when the switch is on and goes cold after the switch has been off for a while.
When the charger is warm then electrons are sill discharging. Energy is being used by the voltage transformer but no useful work is being done. This is wasteful. Make sure all transformers are switched off at the socket so they don't get warm.
Have we got lots of potential as well Sir.
