Other Guest interview, whole class Activities

  • Big Feet
    This is a fun whole class activity that illustrates how a small percentage of the global population have larger eco footprints than the majority.
    (From module Module 1: The Big Picture)
  • The Green House
    This downloadable activity allows pupils to make energy choices for the home to see how they raise or lower emissions.
    (From module Module 3: Energy)
  • Mystery Guest
    A visitor from the energy industry is invited to the class to be interviewed by the pupils.
    (From module Module 3: Energy)
  • The History of Stuff
    This group activity allows pupils to research how local trade and industry has changed over the years.
    (From module Module 6: Stuff)
  • Regional Planning – ‘Stuff’
    This group activity allows the pupils to create their own sustainable transport plans for the region.
    (From module Module 6: Stuff)
  • The Sustainable Regional Plan
    Pupils collate the work on regional planning in previous lessons, to create a comprehensive sustainable plan for the region.

Things needed for this Module...

Solar Power Cans:
  • 4 aluminium drink cans of which:
    • 3 are painted with matt black paint (or blackboard paint) of which:
    • 2 have been insulated with pieces of insulation that is safe to handle – sheeps wool for example covering the back half or two thirds of the can of which:
    • 1 is placed in a clear plastic bag or container  such as a clear 2l bottle with the bottom cut off
  • Thermometer
  • Recording sheet
The Green House:
  • Downloadable activity from CAT (coming soon)
Walk the walk:
Regional plan - energy:
  • Hopefully the mystery guest will be able to stay for this session
  • Maps and aerial floor photo mats if you have them
  • Variety of media for recording
Power Up! – Solar Power:
  • Whole class in groups
  • Small photovoltaic cells, motors, crocodile clips and propellers (available from the Centre for Alternative Technology shop and other education suppliers)
  • Clean floatable materials – eg plastic bottles (with lids), cartons and cups and containers, rubber bands
Power Up – Wind Power:
  • EPK20850
    ‘Wind Kit’ from the Centre for Alternative Technology
    (or a wind power kit from another education supplier)
  • Bits of corriflute plastic and/or other suitable scrap materials like thin card and plastic, scissors, tape.
  • Large electric fan with wide blades, the ones which come in cages designed to sit on the floor are best. (tall bathroom fans with thin blades will not work so well.)
Mystery Guest:
  • Mystery guest from the sustainable energy industry. This could be someone who works to install renewable energy systems, or an engineer who designs them. It could be someone from the council with responsibility for energy efficiency, or someone who promotes energy efficiency. Or it could be someone from a local group such as Friends of the Earth.

Power Up – Wind Power

Power Up – Wind Power

Download  | Print |

This group activity allows pupils to design and make their own wind turbines that generate electricity.

What to do:

The pupils will have already seen different types of wind turbine design on the slide show. You might want to extend this knowledge by showing them other types of design. (See extension ideas)

Set up the wind rig in advance according to the instructions, and connect a turbine that you have made to a voltmeter. Use a large electric fan to represent the wind. With pupils help, record the amount of electricity you have generated. In groups set the pupils the task of designing and building their own generators from corriflute plastic (that comes with the kit and can be ordered from education suppliers), or any other scrap materials. Remind them that they can experiment with numbers, shapes and sizes of blades. Each group will be given a hub, and some dowelling to attach their blades to the hub. When they are ready, they can bring their hubs to the test rig. If the turbine doesn’t turn, encourage them to work out why. They may not have angled their blades for example, so that the wind is just pushing against the turbine instead of turning it, or the blades may be too small and thin to catch the wind. With support, encourage them to experiment for themselves and improve on and develop their designs.

(The Wind Kit contains full instructions both for electricity and mechanical power generation.)
