Schools now place a greater emphasis on learning about alternative energy sources, including wind. In some areas, large wind turbines provide a portion of the energy to UK households. Providing a hands-on example for primary school pupils may help them better understand how a windmill or wind turbine works and how it can be used to create energy. This simple project is appropriate for students aged seven and older, and uses recycled milk cartons for construction.
- Skill level:
Things you need
- 2.25 litre (1/2 gallon) milk carton
- Wine bottle cork
- Double-sided tape
- Electric fan
- Construction paper
Use a pair of scissors to cut a wine bottle cork in half.
Place a milk carton on the work surface. Push a thumb tack through the back of the carton to the front, about 7.5 cm (3 inches) below the top of the container.
Push one half of the cork on to the back of the nail, over the nail's head. This will help hold the nail in place and prevent injury. The pointed end of the nail is the front side of the windmill.
Draw a large cross shape on the piece of cardboard, making each arm of the cross 2.5 cm (1 inch) wide.
Cut out the cross using scissors.
Push the pointed end of the nail through the centre of the cross. Push the remaining piece of the wine bottle cork on the pointed end of the nail. The cork helps secure the cross shape in place and prevents the likelihood of a child sticking himself with the end of the nail.
Draw windows, doors or decorations on construction paper. Glue them on to the windmill to decorate.
