TRANSCRIPT
The GreenbirdDue to the shape of the craft, especially at such
high speeds, the wings provide lift; a useful trait for an aircraft, but very hazardous for a car. To
compensate for this, the designers have added small wings to
"stick" the car to the ground, in the same way Formula 1 cars
do.
The Wind ExplorerA German engineered vehicle called ‘Wind
Explorer’ has managed to travel 5000km across
Australia, using a combination of lithium batteries, a wind
turbine and a large kite.
VocabularyWind- blowing air What causes Wind?- Uneven heating of the atmosphere from the
sun- Irregularities of the earth’s surface- Rotation of the earth
Wind energy- describes the process by which wind is used to generate mechanical and electrical energy.

What is Energy?Energy is the ability to do work, to make things happen, to cause change, or to start motion.
Energy can move (be transferred) and change (be transformed) but it cannot be destroyed.
EnergyHumans use energy to be active
- To walk, talk, play basketball etc. We use energy to power our appliances, vehicles, lights etc
Life as we know it would not be possible without energy production and consumption
Energy Energy is everywhere!Sometimes you can:
Hear energy (sound)Feel energy (wind)Taste energy (food)See Energy (light)
