learning intention
I understand the concept of wind energy, recognize its significance in sustainable energy production, and be able to identify real-world applications of wind turbines.
I have experimented with different windmill sail designs, made observations, and analysed data to comprehend the factors influencing windmill efficiency and how sail design affects wind energy capture.

Whole class activity:
in pairs, find other machines in the classroom - write them on a sticky and group them into categories on the board. Prize for the groups who find more than 4 different TYPES of machines.
Simple machines allow us to do more work with less effort - compare cutting a circle with scissors vs just hands.
In groups in 5 min brainstorm and list as many sustainable and renewable energy
