How can we 'catch wind' so a windmill performs a helpful task?
How can we 'catch wind' so a windmill performs a helpful task?
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.
Knowledge & understanding
Brainstorming simple machines, renewable and sustainable energy.
Investigation Skills
Testing Sails Design Worksheet - on Google Classrooms.
Knowledge and understanding
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
Why did William build the windmill?
Investigation skills
How can we make a fair test?
What things can we change? (independent variables)
What things do we need to keep the same? (controlled variables)
Equipment
Fan
toy car
masking tape
measuring tape
scissors
blue tack
skewers
cotton reels
sail materials
In groups, discuss and design your sail. Fill out the Testing Sail Designs Worksheet.
Think about:
material
size
shape
Test out your sail on the sail car and record your results on the Testing Sail Designs Worksheet.
