How to build a wind turbine by the Australian Museum.
What you need; recycled bottle, thick wooden skewer, paper drinking straw, thumb tacks, a sharp pencil, cotton or string, sticky tape, scissors, ruler, hair dryer and thick paper or card.
Using the card, draw and cut three blades approximately 15cm long. Engineers and inventors look to the living world for design solutions. Look at the curved shape of bird and insect wings to inspire your designs.
Cut the card into a circle, approximately 5cm in diameter.
Cut 1cm slits around the circle three times at equal distances. Cut a 1cm slit in each blade.
Slot all the blades into the round circle.
Attach the circle of card to the wooden skewer with a thumb tack.
Using a sharp pencil, poke a hole at the top of the bottle on both sides.
Push the straw through both holes.
Push the wooden skewer through the straw.
Attach the end of a length of string to the wooden skewer using tape and twirl it around.
Test your wind turbine using a hair dryer or fan. Watch the string wind around to see how efficient your wind turbine is.
